The Hot Zone Questions 1, 2, 3

2009-09-08T17:50:00.000-07:00

1] I thought the book The Hot Zone was very interesting. I liked the fact that the book was very detailed and explained everything clearly. Some parts of the book was very gruesome, other then that it was a great book. I think we had to read the book before taking AP Biology because it went into dept about a variety of viruses.

2] a. A virus never really dies. Once the host is dead the virus finds a new host to live and infect.

b. A virus can spread through bodily fluids and through infected air.

c. Once you become infected with a virus you don't know you have it till three to seven days later.

3] The article is relevant to the story in The Hot Zone because they both talk about how a virus spreads and how the virus affects and spreads through monkeys. The article and the book talk about how Ebola started and the origin of the virus.

1. I thought the book was really good. At first i was a little nervous that i wouldn't like it. As i started to read it got better and better. I think one of my favorite things baout this book was how detailed it was. It really showed you exactly what was going on. The details helped you paint a picture in your mind.

2. a) When a person has become infected wiht ebola, their cells have been taken over by crystalloids. Crystalliods are diease forming and will make the cells explode eventually. When the book would talk about a person "bleeding out" this is what was really going on inside them.

b) Another fact i learned from this book is that viruses never truely die. When the host they are in die they wait to find a new host to take over.

c) One last fact that i learned which made me a little scared. A viruses can in fact be obtained from breathing it in from the air.

3. The article on malaria relates to The Hot Zone because the two diseases were given to humans from monkeys. In the book the first cases of ebola were found in monkeys back in the late 1960's. The first man to come down with the marburg agent worked with monkeys as living. In the article, it talks about how malaria is caused from a parasite which is common on chimpanzee's.

11

Spiders have segmented bodies. A spiders body is divided into two easily recognized parts, the prosoma,composed of the fused head and thorax and the abdomen.

12

Flowers are known to reproduce through asexual reproduction. Asexual reproduction is the process by which an individual inherits all of its chromosomes from a single parent and is genetically identical to the parent by the process of meiosis.

Hot Zone questions

2009-08-31T10:42:00.000-07:00

1. I thought the book was excellent. It was really interesting, and I couldn't put it down. What I like best is that while reading it, I was learning things I would've never known about ebola and marburg, and the other diseases involved with monkeys. I think we read it before AP biology to get an understanding of how biology works. It helped me understand how diseases work inside the body, and what they can do to you.

2. a) When someone has ebola, their cells are taken over by the disease forming crystalloids, and eventually explode. That causes the body to "bleed out" which means all of their organs bleed and don't stop until there is no blood left.

b) Ebola is a deadly disease, which can be transmitted through contact with infected blood. Once you are infected, there is no cure.

c) Biosafety level 4 procedure includes stages before you can actually enter the hot zone. Sharp objects are not normally used inside a hot zone becuase they can cause rips or tears in one's suit, which could cause that person to be infected. Someone in a level 4 hot zone must wear a biocontainment suit. The room is filled with negative air pressure so the disease cannot escape.

3. The article on malaria is relevant to the situation in the hot zone, because the disease originates in animals and can be passed on to humans. The animals starting with the disease are chimps, and in the hot zone monkeys are being tested for ebola. Both diseases have been around for many years. The diseases can last for a very long time, which is why they must take precautions so the disease doesn't inhabit humans. There are two different parasites, as there are different types of ebola. Also no one knows where malaria exactly came from, like ebola.

50. Endosperm

Endosperm is the tissue produced in the seeds of most flowering plants. It is the tissue containing stored food in a seed that surrounds the embryo and is eventually digested by the embryo as it grows at the time of fertilization.

49. Xylem

Xylem is the wood of a tree, made up of strong fibers, tracheids and vessels. It is vascular tissue designed to help transport water and minerals from the root to the leaves. This is a picture of the bottom of a tree. Xylem helps this tree's leaves recieve enough water.

48. Rhizome

A rhizome is a horizontal underground stem, with leaves and buds, that serves as a storage organ and a means of vegetative propagation. It is a horizontal underground stem of some plants that sends out roots and shoots from its nodes.

47. Biome

This is a picture from Shelter Island. Beyond the water is a forest, which is an example of a biome. A biome is aliving community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region. Biomes include: permanent ice, mountain, desert, grassland, scrub forest, chaparral deciduous forest, taiga, and tundra.

46. Radial Symmetry

This lemon is a picture of radial symmetry. Radial symmetry is a form of symmetry in which the parts of an organism are arranged concentrically around a central oral/aboral axis and more than one imaginary plane through this axis results in halves that are mirror-images of each other.

45. Dominant vs. Recessive

This picture shows a dominant gene vs. a recessive gene. Brown hair is dominant (D) over blonde hair (d).

44. Endotherm

43. Cambium

Cambium is a layer of active cells that separates the xylem and the phloem. These cells produce the new xylem and phloem that are represented by the annual rings of trees. This picture is part of a tree stump.

42. Evidence of different alleles for the same trait

Alleles are either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character. Some alleles are dominant over others. My mom's eye is brown and my sister's eye is blue/gray.

41. Adaptation of a Plant

Plants have adaptations to help them survive (live and grow) in different areas. In this picture, this plant adapted to conditions of growing in between concrete.

40. Auxin Producing Area of a Plant

Auxin is a plant harmone that stimulates growth. Auxin moves only downward but gravity does not cause its movement. It is generally produced by apical shoot meristems and developing leaves.

39. Mating Behaivor

I was being "very careful" when I took this picture of "mating behaivor." Mating is a very essential process for all living organisms on this earth. In order to keep a species alive, mating is necessary. Many animals exhibit different mating behaivors.

38. Pollinator

Although it is hard to see the bee in this picture, it is an example of a pollinator. The bee is an insect that carries pollen from one flower to another.

37. Modified Root of a Plant

This carrot is considered to have a modified root. A modified root is the usual underground portion of a plant that lacks buds, leaves, etc. These include carrots, turnips, and beets.

36. Modified Stem of a Plant

Modified stems located below ground are bulbs, corms, rhizomes, and tubers. This picture is an onion which is considered to be a bulb.

35. Genetic Variations within a Population

In this picture, you can see the same species of flowers. However, the physical colors of them are different. This shows a genetic variation.

34. Difference between Monocots and Dicots

In this picture, the grass is a monocot while the carrot is the dicot. A monocot is any of various flowering plants, such as grasses, orchids, and lilies, having a single cotyledon in the seed. A dicot has two cotyledons and the stem grows by deposit on its outside

33. Gymnosperm Cone

This is a picture of a gymnosperm cone. Their female sex germs reside in ovules, as in regular flowers, but the ovules themselves are not enclosed within the flower's ovaries, as they are among flowering plants

32. Flower Ovary

A flower ovary is an ovary in a part of the female reproductive organ of the flower or gynoecium. In this picture, I zoomed in so the inside of this flower's reproductive organs are visible.

31. Cuticle Layer of a Plant

This is a cuticle layer of a plant. The cuticle layer is a protective layer covering the outer cell layer (epidermis) of the green, aerial parts of land plants. Cuticles protect plants against various kinds of physical and chemical hazzards.

30. Spore

A spore is a haploid reproductive cell, usually unicellular, capable of developing into an adult without fusion of another cell. In this picture, the middle part of the flower contains the spores used for asexual reproduction.

29. Calvin Cycle

The Calvin cycle (or Calvin-Benson-Bassham cycle) is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. In this picture, you can see the dark spots or dark reactions of C3 photsynthesis on these leaves.

28. Parasitism

Parasitism is a living arrangement in which an organism lives on or in an organism of a different species and derives nutrients from it. In this picture, a fly feeds off of the microorganisms on this piece of dog feces.

27. Tropism

Tropism is a response to an external stimulus. This plant has the tendency to move towards a specific target (the sun). You can tell that it is growing more towards the left where the sun shines through the window.

26. Lipids for Storing Energy

Lipids are any group of organic compounds including the fats, oils, waxes, sterols, nucleic acids, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body. This picture displays a person and one of the "fatty" parts of the body.

30.

This tree trunk found in my backyard is an example of cambium. The vascular cambium is located in the vascular tissue in the trees. It is the source of the secondary xylem and secondary phloem.

29.

This is an example of lactic acid fermentation. Glucose, sucrose, and fructose are converted into cellular energy and the product, lactic acid. Cardiac muscle cells are highly soluble to lactate. That's why they always say milk does the body good!!

28.

This bread is an example of grain-based fermentation. Sugar is converted into alcohol using yeast or bacteria. The alcohol is baked out to make the bread.

27.

This flower, although hard to see, has pollen in the center. Pollen is a fine powder that consists of pollen grains, which produces the male sperm cells of plants. Each grain of pollen contains vegetative and generative cells.

26.

This is a picture of my little cousin's frogs. These frogs are examples of ectotherms because they are cold-blooded. They are dependent on environmental heat sources and have low metabolic rates.

25.

This is the cuticle of a plant found in my backyard. A cuticle is a tough but flexible outer-covering of any organism. The cuticle serves protection differs in structure and chemical composition. It is produced by the epidermal cells of leaves and the cuticle minimizes water loss.

24.

These are my father's two birds. They are examples of heterotrophs. They are consumers in the food chain because they cannot produce their own food. They eat nuts and seeds and break down complex organic compounds.

23.

Veins are examples of transport proteins. Transport proteins are proteins that moves ions and small molecules. They assist in the movement of diffusion or active transports.

22.

This is an example of an amniotic egg. This egg was hatched by a chicken and an amniotic egg is an egg produced by birds, mammals, or reptiles.

21.

This is a rhizome, which is a horizontal stem of a plant that is found underground. The rhizome is used by farmers and gardeners to propagate the plants in vegetative reproduction. Ginger, asparagus, and Carras are propagated this way.

20.

This is a blurry picture of a worm with a segmented body. Each segment bears the same structure so organs are equally divided between all the segments so it's not as dangerous if one segment gets hurt.

19.

This is my cousin Julia showing off her skeletal muscles. Regulatory proteins are proteins that regulate the contraction of muscles by controlling the interaction of myosin and actin. Calcium is the most important component of the reaction.

18.

There are six different kingdoms in biological classifications: plantae, protista, animalia, fungi, eubacteria, and archaebacteria. My cousin Julia is in the animal kingdom, along with many other mammals. The animal kingdom consists of multicellular and eukaryotic organisms.

17.

This is a picture of me and my cousin Johnny. His nose and ears are made up of a connective tissue called cartilage. Cartilage makes up the entire skeleton and provides support but is not as flexible as muscle and not as hard as bone. Cartilage also takes more time to grow and repair.

16.

This is a picture of my nail and is an example of structural proteins. This structural protein is called keratin and is found in hard or filamentous structures like nails, hooves, or animal shells.

15.

This is a plant in my backyard and is an example of a plant hormone called gibberellins. This hormone increases the developmental process of germination.

14.

This grass found in my aunt's backyard is an example of an autotroph. Autotrophs use the energy from the sun and water from my aunt's sprinklers to create their own food by the process of photosynthesis. They are producers in the food chain.

13.

This is a picture of my Begonia plant in my backyard. It is an example of a long-day plant meaning that in order for the plant to thrive, it should have sunlight for more than 6 hours a day.

12.

This small tree found in my aunt's backyard has bilateral symmetry. Bilateral symmetry means you can cut the tree vertically and each side will be the same as each other.

11.

This is a picture of a horseshoe crab found at West Meadow Beach. They are found swimming in the ocean and in most saltwater marshes but their adaptation is that they have legs that they can walk up onto the sand for mating season. They need to mate in the sand so the females can keep their eggs in the sand and protect it from predators.

10.

This is a picture of a razor clam found in a creek for my marine biology class. It has a fascinating analogous structure. Most mammals have "legs" used to move around and support itself. The razor clam uses its one leg (the long thing sticking out of the middle) to dig into the sand to a safe depth.

Hot Zone Questions 1, 2, 3

2009-08-31T06:19:00.000-07:00

1. The Hot Zone was, in my opinion, one of the best books I've read. This was mainly because it was something that was real and not a piece of fiction. I liked how it was suspenseful enough to get the reader involved in the story line and feel like they were experiencing what the characters were living through. I don't have many dislikes about this book, I thought it was a well written piece of literature. The explanations of the ebola virus were anything but boring because it is hard to believe something so small has the ability to destroy an entire human population. I think you had us read "The Hot Zone" before AP Biology because we were introduced to many biological terms and the life of a true "biologist."

2. Biological Facts:
1. Ebola has 3 types: Ebola Zaire, Ebola Sudan, Ebola Reston. What this virus does is enter the body (with an incubation period of 2-21 days) and attack every organ with congealed blood. This makes someone bleed out from every oriface of their body. If another person touches infected blood, they are easily effected.
2. A hot suite is a group of biosafety Level 4 laboratory rooms. A researcher must take many precautions before dealing with a hot agent. First, a researcher must change out of their clothes and put on a type of scrubs suit to change into a biocontainment suit. Negative air pressure is used in case of a leak so that air will flow into the zones rather than out having a disturbing effect on the normal world.
3. A crystalloid or "brick" is a pure crystal like block of packed virus particles that grows inside a cell. After a cell is infected with the ebola virus it bursts and develops crystalloids.

3.The following article, "First Origin of Malaria may have been found" relates to Richard Preston's "Hot Zone." Malaria, like Ebola, has been said to be around for many years, even ancient times. Both diseases jumped from animal to human and chimps are said to be the primary source. Some chimps harbor two parasites which come from a common origin. This is like how ebola has many different strains from a common origin as well. Lastly, there is always a growing understanding of malaria and ebola but no one can pin out it's exact source of development or how long it has been around.

Hot Zone: Question 1

2009-08-30T15:30:00.000-07:00

Tell me what you thought about the book, The Hot Zone. What did you like the best about it? What did you like the least? Why do you think I had you read it BEFORE you took AP Biology?

Hot Zone: Question 2

2009-08-30T15:15:00.000-07:00

Explain three (3) biological facts you learned from reading The Hot Zone.

Hot Zone: Question 3

2009-08-30T15:00:00.000-07:00

Read the following article on malaria from Newsday science section: First origin of malaria may have been found. Explain how this article is relevant to the story in The Hot Zone.
