The skeletal system supports body structures; muscular system carries out the nerve commands to produce movement.
Hope this helps!
Answer:
Adaptation
Explanation:
In this case predation is the selection pressure for natural selection in the mice population. Because the black mice stand out against the brown sand dunes backdrop, they are easily located and predated on by the hawks. Therefore, black mice have a lower chance (compared to brown mice) to reach reproductive age and pass down their genes to the next generation. With subsequent generations, therefore, there will be more and more brown mice in the population.
Answer:
"Activation of CD4+ helper T cells" is the correct choice.
Explanation:
- The major complicated of histocompatibility II seems to be the chemical compound for something like the T cells that presets antibodies.
- Antigens collected from those in the pathogens become transformed as well as inserted into a large histocompatibility system that's also distributed on either the cellular cell surface membrane representing antigen as well as the trigger is perceived by complicated systems of T cells as well as MHC II but rather contained throughout CD4 + support T cells.
A decrease in the paved surfaces on earth will increase amount of light reflected or increase albedo.
<h3 /><h3>What is a paved surface?</h3>
A paved Surface refers to a surface covered by concrete, asphalt, masonry, or a similar material.
Paved surfaces have low albedo, that is they have low light reflectivity.
<h3>What is the effect of paved surface of Earth on albedo?</h3>
Since paved surfaces have low albedo, a decrease in the paved surfaces on earth will increase amount of light reflected (albedo).
