Answer:

cell growth and manipulation

Explanation:

The nucleus of the cell controls cell growth and manipulation. This involves regulating gene expression, initiating cellular reproduction, and storing genetic material necessary for all of these tasks. In order for a nucleus to carry out important reproductive roles and other cell activities, it needs proteins and ribosomes.

Answer:

The nucleus of a cell controls all the functions of a cell.

Explanation:

The nucleus of a cell regulates the activities of the cell such as growth. It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and cell division. Only the cells of advanced organisms have a nucleus.

A human eats a meal and afterward their blood glucose levels rise. Explain how the human body responds to return their blood glu

Nookie1986 [14]

Answer:

Explanation:

The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.

Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).

Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two

Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.

postnew [5]

Tigers are a very important part of the food chain, but sadly they are going extinct. Their habitats are being destroyed, forcing the tigers to kill farmers livestock. In some countries tigers are still used for medicinal purposes, so they are often hunted for their teeth and pelts. Tigers may not seem important but they play a very important part on the food chain. Without these tigers the population of boars and other prey would sky-rocket and that would not be good for the environment.

Of the three primary germ layers, which is responsible for developing into nervous tissue?

nadezda [96]

Answer:

D. All three primary germ layers develop into some more type of nervous tissue

Explanation: All of the primary germ layers have specific nervous tissue development. a) Ectoderm - neuroectoderm (neural tube, neural crest). b) Endoderm develops into (among others): The digestive tract and its attached glands; the inner lining of some organs, such as the lungs, nervous tissue; epidermis . c) Mesoderm - notochord signals the ectoderm to develop the neural crest more
