Proteins are made up of monomer units called amino acids
Answer:
cells can get energy from minerals
Explanation:
True
The drug that to a receptor in the nucleus. This binding makes on a gene to make a protein. This drug is actually lipophilic and hydrophobic, the correct option is A.
What is receptor?
In biochemistry and pharmacology, receptors are protein-based chemical frameworks that transmit and receive signals that can be assimilated into biological systems.
As the drug is crossing the lipid membrane so it should be lipophilic and hydrophobic to be able to bind the receptor as in the given situation.
Thus, the correct option is A.

Answer:
Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA. With blood donation, usually most of the white blood cells are filtered out.
Explanation:
because red blood cells don't have the DNA containing nucleus and mitochondria
A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.
Explanation:
- Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle.
- In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways.
- The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis.
- The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur..
