<span>A person who has rh- blood can develop rh agglutins through;
1. Pregnancy.
2. Transfusion.
3. Exposure to blood.
Agglutination is termed as clumping of particles. It is the process which occurs when an antigen is mixed with its corresponding antibody known as isoagglutinin.
When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.</span>
Answer:
c
Explanation:
catalysts are used up in a chemical reactiob
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
It's the phases of the mitosis cycle.

I'm pretty sure that these are correct.
Three examples are red blood cells, root hair cells, and sperm cell.
