Answer:C

Explanation: Atmosphere is gases and biosphere is living things on earth's surface. Therefore we can eliminate a and b because those involve the hydrosphere. We can also eliminate d because nothing in there talks about the atmosphere. Carbon dioxide comes from the atmosphere and trees are part of the biosphere so that would have to be the answer.

Why does synthetically produced RNase refold incorrectly if the reducing agent is removed before urea removal?

<h2>Disulfide bonds interaction </h2>

Explanation:

The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"

In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a

GaryK [48]

Answer:

Bb X bb

Explanation:

It is given that the allele B for the black coat is dominant over allele b for a brown coat.

A dominant allele always leads to the expression of the dominant trait in the heterozygous condition.

When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait.

Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
The cross is shown in the punnett square.
