In a Section A, the number of seals are less in number. And In section B, number of seals are more in number.

Seals are pinnipeds, which are the only mammals that feed in the water and breed on land. They are divided into three different families: phocidae, which includes eared seals, otaridae, which includes non-eared seals, and odobenidae, which includes walruses.

Seals have a thick coating of blubber that protects them from the cold; a transparent membrane covers their eyes; their nostrils close; and their blood circulation to most of their organs is decreased while diving.

Seals have the ability to snooze underwater and even surface for air without waking up.

Answer:

The amount of air pressure can affect how far a soccer ball travels when kicked. In general, high-pressure systems are associated with dry and fair weather, which can lead to a harder and more predictable playing surface. This can make it easier for a soccer player to control the ball and kick it with more accuracy and force, resulting in longer distances. On the other hand, low-pressure systems are associated with storms and wet conditions, which can make the playing surface softer and less predictable. This can make it more difficult for a soccer player to control the ball and kick it with accuracy and force, resulting in shorter distances. Therefore, the air pressure in a particular region can have a significant effect on how far a soccer ball travels when kicked.

Answer:

It is a single layer of cells called meristematic cells that lies between the xylem and phloem. It is also called cambial zone.

Explanation:

A) change in the DNA nucleotide sequence, particularly at the nucleotides coding for the third position of a codon, can occur without changing the translated protein because the triplet code is excessive.

B) suggest about the relative advantages of searching for related genes based on nucleotide similarity vs protein similarity.

Protein clusters are expected to evolve and change more gradually than the characteristics that encode them. The majority of codons are adaptable in their nucleotide locations, which allows the DNA sequence to accumulate modifications without affecting protein structure. Given that amino acid modifications may alter the structure and functionality of the protein, protein groupings will grow and diverge all the more gradually. Since the succession of amino corrosives is essentially forced, natural selection will eliminate many deleterious amino corrosive modifications. As a result, the pace of advancement in the amino corrosive succession will slow down, and the amino corrosive arrangement will have more prominent grouping protection as compared to the nucleotide arrangement.

Hexokinases, phosphofructokinase-1, and pyruvate kinase, three enzymes that all catalyse irreversible processes, control glycolysis. In reaction to circumstances both inside and outside the cell, the glycolytic pathway's flow is modified.

Hexokinase catalyses the glycolysis process' initial exergonic step. The hexokinase reaction is not necessary, though, when the source of the glucose-6-phosphate is skeletal muscle glycogen as opposed to free glucose. Pyruvate kinase catalyses the final step in glycolysis, making it an unsuitable option to control the complete system. In Step 3, phosphofructokinase catalyses a highly exergonic reaction. This is after the entry of glucose-6-phosphate from glycogen but close to the beginning of the process, thus it can control the entire pathway.

Charles Darwin advocated the expression "natural selection", standing out it from counterfeit choice, which in his view is purposeful, though natural selection isn't.

Variety exists inside all populaces of organic entities. This happens mostly in light of the fact that irregular transformations emerge in the genome of a singular organic entity, and their posterity can acquire such changes.
