regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
Answers
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.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.
Answers
Answer:
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.
What is pulmonary system?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.

How many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
Answers
Explanation:
You multiply 40 by 60 to get 2,400
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.

a. keep body temperature the same as the external temperature
b. increase body temperature
C. decrease body temperature
d. regulate blood pressure
Answers
Answer:

Explanation:
this is because when you shiver your blood vessels contract which then increases your body temperature
If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.
What do you mean by Environment?An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.
The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.

What is a isotonic solution? How does it affect a red blood cell?
What is a hypertonic solution? How does it affect a red blood cell?
What is a hypotonic solution? How does it affect a red blood cell?
Answer plz!
Answers
Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks
Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
An isotonic solution is one wherein the solute concentration across the semipermeable membrane is the same resulting in an equilibrium state.
They do not shrink or swell in an isotonic saline solution, i.e., 0.9% w/v solution of sodium chloride
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
Now, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 2% w/v. The sodium chloride concentration of 2% w/v is greater than the RBC’s sodium content and hence the solution is hypertonic. This will result in shrinkage of the RBCs known as crenation
When a solution has a lower solute concentration than the solution present across the semipermeable membrane, it is known as a hypotonic solution. As a result, when a cell is placed in a hypotonic solution, an osmotic pressure gradient forces the solvent to move into the cell in order to attain equal solute
In another situation, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 0.1 % w/v. The sodium chloride concentration of 0.1% w/v is less than the RBC’s sodium content and hence hypotonic saline. This will result in swelling and eventually bursting of the RBCs which will result in the release of hemoglobin. This is known as hemolysis which is a very dangerous situation.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism
Answers
Answer:
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.
What is the probability that their first child will have 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.
Do both parents have to carry the albinism gene?
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.
