Why do some stars become red supergiants?

Biology
1 answer:
Shtirlitz [24]3 years ago
3 0

Answer:

Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

It should be C! (: Fate mapping because it is used do dermine tissue linage!
While Differentiation is used when one cell type changes from one cell to another.
When it comes to the process an undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation.

If you want to see something in fine detail, you should focus the light on which part of your retina?
Dmitry_Shevchenko [17]

If you want to see something in fine detail, you should focus the light the cornea. The lens works together with the cornea to focus light correctly on retina.

When light hit on retina special cells called photo receptors turn the light into electrical signals. The lens are the clear part of eyes behind the iris that help to focus light and image on retina to see something clearly.Lens is the important part of eye when it comes to focusing light so that we can see perfect clear image.

The retina is the most sensitive part which can effect by more light because retina convert incoming light into electrical impulse.

A person's blood type is determined by the:_______
matrenka [14]

Answer:

) Presence of specific glycoproteins on the cell membrane

Explanation:

When specif glycoproteins(antigens)  or antibody are present on a cell membrane of Red blood cell,they can  be used to identify the blood type.Antigens are substances capable of triggering an immune response in a cells.

In addition,they function in transport of molecules across the RBC. They help in the maintenance of the RBC,and aiding the arrest of cells capable of causing diseases to the body.

Therefore,they are good determinants of blood types,based on this two types of antigens present in a  blood type.

These two antigens  used for classification of blood types are the 1-the ABO antigens 2,the Rhesus antigens.

Essentially,when a WBC produces an antibody ,which is a molecule that defends the body,If this is not compatible,the antibody will recognize it as a foreign body and attack it.Thus such blood types are not compatible. Thus the antibody-antigen reaction are good for knowing and classify blood types.

Antigen can also be glycoprotein,carbohydrate or glycolipids.

Generally blood types are inherited from both parents.Therefore the antigen present on the RBC are combination of the alleles from each parent.
