I’m pretty sure A can receive A and O. O is a universal blood type that can donate to any other blood type. This is because O blood does not have signal proteins surrounding it, so blood cells from other blood types do not attack the O blood cells. A can also receive A, because the A proteins recognize the other A proteins.
<span>A zygote begins as a one-cell structure that is created when a sperm and egg merge.
In the embryonic development of people and different creatures, the zygote arrange is brief and is trailed by cleavage, when the single cell moves toward becoming subdivided into smaller cells. we can also define zygote as a cell that is formed when two gametes meet.

After a steroid hormone binds to its intracellular receptor, transcription of specific genes occurs. The activated receptor moves into the nucleus and binds to DNA
<h3>What is steroid hormone and intracellular receptor ?</h3>
Target cells have steroid hormone receptors in their nuclei, cytoplasm, and plasma membranes. They are typically intracellular receptors (often cytoplasmic or nuclear) that start the signalling processes for steroid hormones, which modify the expression of genes over the course of hours to days.
- By attaching to intracellular receptors, steroid hormones control cellular functions by changing the expression of specific nucleotide sequences. Since the majority of steroid receptors in target cells reside in the cytoplasm, they must enter the nucleus to change gene expression.

Answer:
I am not too sure but maybe A?
Explanation:
Because plants are part of the biosphere and land is part of the geosphere
I am sorry if it is wrong
Answer:
The slime molds are important to ecosystems because they act as decomposers which will release nutrients back into the environment. Earth basically depends on protists because they supply oxygen and are critical in the food chain.
