The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.

Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).

This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.

CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.

For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.

Answer:

is it water?

Explanation:

As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.

Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.

The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

Answer:In fact, most of our organs have some turnover in cells, which explains why they're younger than our biological age. The human heart, skin, intestines, and even our bones are slowly replaced over time, meaning that a limited amount of damage can be reduced. However, this doesn't extend to limbs.

Humans have stem cells, but they aren't readily available to assist in healing. Because most other mammals are similar, they aren't very good at regeneration. Amphibians and some fish have more readily available stem cells, which are usually rather good at regeneration.(please mark brainliest <3)

Explanation:

Seawater has many different gases dissolved in it, specially nitrogen, carbon dioxide and oxygen. It exchanges these gases with the atmosphere to keep a balance between the ocean and the atmosphere.

An atmosphere is defined as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.

Dissolved oxygen and carbon dioxide are important for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis.

Cold water holds more gas than warm water and seawater with low salinity holds more gas than high salinity water. Deep water, that has a high pressure, holds more gas than shallow water.

Explanation:

"Blood from the heart is pumped throughout the body using blood vessels. Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart."

Basically, blood from the heart is taken away by arteries and then into capillaries, transferring oxygen to cells.

I hope I could help!

The circulatory system of human body brings about oxygen to the every cell by the help of blood. The heart of human body helps to pump up the blood with oxygen and makes it oxygenated.

A size of a human heart is a size of a human fist it has 4 chambers where with 2 auricles and 2 ventricles. The auricles receive the oxygenated blood and the ventricles get the deoxygenated blood.  

The human heart is bringing oxygen to the cells of the body where the oxygen combined with the Fe component that is iron of the blood and reaches every cell of the blood through the blood. Blood is transported to every cell of the body through the blood vessels.

Arteries carry the oxygenated blood and ventricles carry the deoxygenated blood where the blood that reaches the cellular level by the veins and the arteries along with the blood vessels that form a network.

Explanation:

The  primary purpose of the  systemic  circuit is for blood to release carbon dioxide and pick up oxygen

The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.

It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.

Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.

The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.

The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.

This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.

Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

Answer:

Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.

Helper T cells secrete cytokines to stimulate the proliferation of B cells.

Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.

Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.

They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

The child has a 1/4 chance of having albinism

Explanation:

I hope this helps!

For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.

This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.

Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.
