Answer:

Melanin is responsible for black colour of hair.

Explanation:

Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.

Which of these statements is true about adaptive evolution? The ability to learn plays a key role in the process of adaptive evo
pentagon [3]
<span>The correct answer is "Sudden changes in the somatic cells of organisms play a key role in the process of adaptive evolution". Adaption in evolution is caused by sudden gene mutations that affect an organism's offspring and give it - potentially - a better chance of survival. For example, a giraffe who passed on a mutated gene for a slightly longer neck to its offspring gave its offspring a better chance of reaching untouched food, and thus a survival advantage.</span>

Choose the answer that places the following events of protein synthesis in the proper order.
Fofino [41]

A) 3,5,1,6,2,4 is the correct order for the  events of protein synthesis.

<h3>What is protein synthesis?</h3>

Protein synthesis (translation) is the process of creating a polymer of an amino acid chain that results in the production of a functional protein. It entails reading information from mRNA (messenger RNA) and assembling an amino acid chain. Ribosomes are the structures responsible for protein chain synthesis.

Protein synthesis is an important process because we rely on our bodies to build the proteins we require to perform important functions. Without protein synthesis, our bodies will be unable to produce hormones, enzymes, and even new muscle.
