If color is an inherited trait in beetles, and birds are more likely to eat brown beetles than green beetles, a. the frequency of the green allele will increase. b. the frequencies of the brown and green alleles will not change. c. this causes the population to evolve due to genetic drift. d. the frequency of the brown allele will increase. e. this causes the population to evolve due to gene flow.

Natural selection changes allele frequencies because some survive and reproduce more successfully than others.

When ash and dust begin to settle on the ground, they eventually become compacted by

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
