These 5 pictures can be related to finding the main message of the diagram. This diagram can be interpreted as the evolution of species on planet Earth because a dinosaur is shown first, a species that lived millions of years ago.

An image of the Earth is then displayed showing the familiar shape of the continents to demonstrate evolution on the Earth's surface.

Then show the grass because this represents the evolution of plant species that were expanding throughout most of the Earth.

Subsequently, a cow is shown as an example of the mammalian animals that exist today and finally the human who is the product of various evolutionary processes that resulted in the society and the world that we know today.

helper t cells secrete ________ to stimulate the proliferation of b cells.

Answers

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.

What are Helper T- 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.

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.

in humans, how does the circulatory system bring oxygen to every cell in the body?

Answers

Answer:

I found this in a science text, hope it helps.

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.

What is the size of a human heart ?

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.

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.

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.

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.

Why do parrots mimic people?

Answers

Answer:

Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.

Explanation:

Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.
