Follicle cells in your scalp assemble proteins to build new hair. this most likely involves reactions.

Dehydration Synthesis Reaction

Explanation:

When water participates in a reaction as a product, the process is called a dehydration synthesis reaction, since atoms of H and O are removed from the molecule, which join together to form a water molecule. This occurs at the bonds between amino acids to form proteins. This also occurs when a cell gathers its proteins to create a structure in the body, an example of this occurs when the follicular cells of the scalp gather proteins to create new hair.

within 30 of the equator hope this

nucleus

would be most reasonable answer tbh
