Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
Answer:
Maybe it's because the temperature was lower than the room temperature!?
From what I can see in the picture, the cell appears that it would take up half of the microscopes view if it were to be pushed to the very edge on one side.
That would be the radius. The radius is half of the diameter, and half of 0.8 mm would be 0.4 mm. The length of the cell is about 0.4 mm.
Now for the width. Since the diameter of the FoV (field of view) is 0.8, we can see that the cell doesn't reach both sides of the circle it is in. It also doesn't appear to take up half of it. So, to get the aprox. width of the cell, we're going to half the radius.
Half of 0.4 mm is 0.2 mm, so the width of your cell is about 0.2 mm.
In artificial selection, nature provided the variation, and human selected those variations that they found useful
The correct answers are:
B. Warmer air promotes more evaporation.
D. Humidity refers to the amount of water vapor in the air.
E. Areas with a lot of surface water have higher humidity than drier areas.
The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.
The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.
