(Odocoileus virginanus)‚ and human (Homo sapien) are all different. The coyote had the dental formula of 3-1-4-2/3-1-4-2 (x2)‚ which produced the total of 40 teeth. The deer had the dental formula of 0-0-3-3/3-1-3-3 (x2)‚ which equaled to 32 teeth. The human species had a smaller number of teeth with the dental formula being 2-1-2-2/2-1-2-2 (x2)‚ which produced a total of 28 teeth. The numbers of molars in the coyote upper and lower jaws were the same as the number of molars in the human (upper + lower jaws)

differences in the range of electromagnetic radiation detected by humans and other animals: Reasons for differences in detection between humans and other animals: The differences between human detection range and other animals detection range relates to their environment in which they live in and their way of life. The detection out of the visible spectrum is usually an adaptation for survival of the organism. Humans detection range of 380-750 nm (visible light) can only detect

1. Plant breeders wanted to produce a better variety of tomato by selective breeding. Two plants‚ of the varieties Tangella and Piranto‚ were crossed. (a) Some flowers of each variety were covered with cellophane bags. The diagram shows a covered flower and a brush. (i) Explain why some flowers were covered with cellophane bags during the selective breeding. .......................................................................................................................... ........

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
