The tooth enamel of apes is thinner compared to that of
hominids.
The tooth enamel is the hardest, most mineralized substance
in the body. It is the most visible part of the tooth and it covers the outer
layer of each tooth. The tooth enamel is composed of several proteins which
form a framework for the minerals that makes it hard. It plays a crucial role
in guarding the teeth from decay.
Answer:
No.
Explanation:
Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
