Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
Adult frogs are on land and they have feet and a body
Tadpoles are in water and they are somewhat like a fish!
A. Neutral water
Less than 7 is acidic (which has 6 letters, 6< 7)
More than 7 is alkaline (which has more than 7 letters). Alkaline = basic
7 is neutral
Selective breeding is the traditional method for improving crops and livestock, such as increasing disease resistance or milk yield.
Genetic engineering is a faster way, which transplants genes for a desired characteristic into an organism. However, genetic engineering offers many potential benefits but carries the risk of unexpected harmful effects.
Ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA and similarities of embryos.
