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>
<span>Adaptive evolution is always changing because the environment is changing continuously.
Hence,
The right answer would be :
</span><span>Adaptive evolution is a fluctuating change in a trait.</span>
Answer:
Here's a quick explanation
Explanation:
Oceanic crust is found under the oceans, (hence "ocean"ic) and are made of multiple layers on oceanic ridges.
Continental crust is found on the outer layer of the crust and makes up the earth's surfaces and continents.
Answer:
1600cm³
Explanation:
The volume of a cuboid can be calculated as follows;
V = L × B × H
Where;
L = length (cm)
B = breadth or width (cm)
H = height (cm)
However, in this question, the area of the book is said to be 400cm². Since area of a rectangle or rectangular-shaped object like the book is L × B, this means that the length and breadth has been combined in the area. Hence;
Volume of the book = area of the book (L × B) × Height of the book (H)
Volume = 400cm² × 4cm
Volume = 1600cm³
Therefore, the volume of the book is 1600cm³.
