Buffer systems in the body maintain proper pH balance in order for life processes to proceed. Proteins found in the blood plasma are often used as buffers.
What makes a protein able to function as a buffer?
O The protein's molecular shape must enable it to bind with other proteins in the plasma.
O The protein must be capable of both accepting and releasing protons.
O The protein must maintain its ability to release various amino acids, thus changing its molecular shape.
O The protein must take on a conformation change according to the activity of the associated enzyme in regulating
the blood's pH.

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?

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.
