AndreaW - Scavenger Hunt 40-50

50. Endotherm- This is a picture of me, Andrea, a Homo Sapien, at the Mendenhall Glacier in Juneau Alaska this summer. I am a warm blooded animal. My body regulates itself keeping a constant body temperature of 98.6 degrees F. This day the temperature in Juneau was about 82 degrees. I was therefore maintaining homeostasis by sweating in the sweatshirt.

49. Adaptation of an animal- Below is a picture of tadpoles and a frog. External fertilization occurs in an aquatic environment. As the tadpoles mature, these amphibians undergo a metamorphosis which transforms them from breathing through gills under water into a land animal with lungs to breath air. These pictures were taken at Clark Gardens in Albertson, Long Island.

48. Animal that has a segmented body. A praying mantis is an insect that has a segmented body. It has three body segments, the head, the abdomen, and the thorax. In an adult the abdomen is elongated and covered by the wings. It has a triangular head. It is a carnivorous insect and eats moths, beetles and bees and crickets. This praying mantis was found on my doorjam.

47. Endotherm- Below is a picture of a stray cat by my house. She is an edotherm which means that she is warm-blooded. This means that she can regulate her body temperature. Endotherms can maintain homeostasis by maintaining a constant body temperature.

46. Biome- Terrestrial Biome- Long Island Pine Barrens. This region is located in Suffolk County Long Island. It is an undisturbed region protected by conservancy laws. The climax community is the pine tree. It is an area of about 900 square miles that lies above ther aquifers that provide Long Island with its drinking water. This picture was taken on the Long Island Expressway around exit 71.

45. Ovary of a flower- This is a picture of a cucumber flower in my garden. After pollination and fertilization the ovary is the location of the developing fruit(it has seeds).

44. Ovary of a flower. Below is a picture of a flower on a zucchini plant in my garden. The ovary is located at the base of the flower in the carpel. The ovary is where the the ovules or seeds are found. This is the location where fertilization occurs after pollination. The pollen travels down into the ovary.

43. Exoskeleton- These crayfish have an exoskeleton. This is an external skeleton the protects and supports the animal. The ee exoskeleton of this crustacean is made of chitin a derivative of glucose. This picture was taken at Pykes Market in Seattle, Washington.

42. Xylem- is one of the two types of transport tissue in vascular plants. It carries the raw materials, water and nutrients,up form the roots up to the leaves where they can be used for photosynthesis (in a living plant).This is done by means of transpirational pull due to transpiration from the leaves.

41. Biome-Temporate decidous forest. The Catskill Mountains, upstate New York are a region of deciduous forests. Many deciduous forests can be found on the eastern half of the North America. The average temperature is 50 degrees F. and the average rainfall is 30-60 inches peryear. Trees in this region include elm, hickory, maple, aok, adn beech. This zone has 4 seasons. With the change in the amount of sunlight the leaves change color and then fall from the trees. Most plants in this region grow towards the sun instead of growing straight up.

40. Biome- Terrestrial grassland- Below is a picture of the Hempstead Plains. This region is located in Central Long Island inNassau County. Once the plains separated the north shore and the south shore of Long Island. Hempstead Turnpike now separates the plains from the south shore. THe plains extended from Queens to the Suffold County border. This region is dominated by grasses and ther herbaceous, non woody plants. Itexists in the temporate lattitudes in terrestrial climates. Rainfall is between 20 and 35 inches per year. This picture was taken in Eisenhower Park.
