ivann1987 [24]

Answer:

Statement B is false.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of  polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.

The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare reces
Serhud [2]

Answer:

The correct answer would be - d. With the end of genetic isolation gene flow took place

Explanation:

It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.

Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.

Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.

Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts,
FromTheMoon [43]

Answer;

The second cell would not be able to produce as much food because it could not capture sunlight.


Explanation;

The first cell has multiple chloroplasts, and the second cell has very few which means the cell with more chloroplasts would make more food.

Chloroplast is an organelle is the cell where the process of photosynthesis (process in which plants make their own food) takes place.

A cell with multiple chloroplasts would make more food through photosynthesis compared to a cell with few chloroplasts.
