Answer: Option B) Antigens
Blood typing is based on the presence of proteins known as antigens on the outer surface of the red blood cell plasma membrane.
Explanation:
Blood groups A, B, AB, and O are determined based on the antigen-antibody reactions between donor and recipient bloods.
For instance,
- Blood type A has antigen A on its plasma membrane
- Blood type B has antigen B on its plasma membrane
- Blood type AB has both antigen A and antigen B on its plasma membrane
- while blood type O has neither antigen A nor B on its plasma membrane
So, antigens is the answer
Answer:
One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
Explanation:
Prokaryotes taht obtain energy from sunlight are called PHOTOTROPH. These prokaryotes use energy from the sun to synthesize organic compound for food and to carry out other metabolic processes. The energy synthesized from the sun is in form of ATP.
Answer:
i am pretty sure its C
Explanation:
Meerkats are specially adapted to living in the harsh desert environment. Dark patches around their eyes help them be effective lookouts by reducing the glare of the sun, much like a baseball player who paints dark lines beneath his eyes. Their eyes also allow them to take in a wide angle view of the scene. This helps prevent predators from gaining an advantage by sneaking up.
Meerkats also possess special adaptations to help them burrow. Their eyes have a clear protective membrane that shields them from dirt while digging. Their ears also close tightly to keep dirt out.
These are just some fact for them where it says that they dig so probbably it is C.
<h2>Answer: </h2>
In real life examples cytoskeleton can be :
<h3>Explanation.
</h3>
If we take cell as a factory, then cytoskeleton is like a building frame of that factory because it provides mechanical support that enables cells to carry out essential functions like division and movement.
If we take cell a whole society then cytoskeleton is like roads to that society because it provides a path for the movement of other organelles and materials.
