Answer: Homeostasis
Explanation: The process of homeostasis is when self-regulation occurs in order to keep balance while adapting to changes.
In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.

So id say the answer is C.
Yes they had multiple tries. But it depends how they recorded the data because they used different wands
Answer:
from what we see from the graph when the children had the 1st vaccine antibodies in the blood raised. then the concentration of the antibodies depleted, after the children had the second dose of the measles vaccine again, the antibodies in the children's blood raised drastically then the first dose.
