Answers

These are called specialized cells. That's because they have a specific function in the body and are not just generic cells used as building blocks of organisms. Many cells build together into a tissue, and numerous tissues build into an organ. Prokaryotic don't have a nucleus and are mostly bacteria.

In which part of the body is glycogen stored? liver blood pancreas exoskeleton

Answers

Answer:

The correct answer is -liver

Explanation:

Glycogen in the body is mainly stored in the liver and muscle tissue because of the action of insulin. They provide a source of energy which can be easily available in case of shortage of blood glucose in our body.

When glucose becomes deficient in the blood, level of glucagon hormone increases in the body which helps in release the glycogen from the liver in the blood in the form of glucose which provide energy to the body.

The liver can accumulate glycogen up to 5-6% of its fresh weight, therefore, the correct answer is first i.e., glycogen.

Glycogen is stored in the liver.

Explanation:

A mutation is a random change in a cell's genetic code due to a variety of causes. The change can be small and insignificant, or it can be major. Mutations can be passed onto offspring through reproduction, thus increasing the genetic variation within a population.

Please explain how treadmilling contributes to actin-based motility in crawling cells. Be specific in why both actin filament growth a d shrinkage are necessary.

Answers

The actin filaments in cell constantly grow and shrink. This occurs through addition or removal of subunits. The two ends of actin filament have different dynamics of addition and removal of subunits. That way, one end of actin filament will grow and one end will shrink so it seems like the filament is moving. This phenomenon, known as treadmilling is characteristic for both actin filaments and microtubules.
