How does natural selection change the frequency of genes or traits over many generations? biology students conducted an experiment mimicking genetic variation and coloration. students used different colored beans to represent animals that might be prey: mice, for example. a student in each group was the predator: a hawk. beans (mice) were randomly scattered on multicolored floor tiles and the hawk collected mice (beans) for 10 seconds. mice not eaten reproduced. three generations of data a shown in the table. which coat color provided the best protection from predators? a) red b) black c) white d) red striped

D) Red striped. If you check the data table, the population with the largest numbers after three generations is the red striped bean (mouse).

USATESTPREP explanation and answer

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
