Answer:
Genetic drift
Explanation:
Genetic drift is a change in genetic allele frequencies of a population. Bottleneck effect, caused by disasters such as in this case, causes genetic drift in a very rapid way hence reducing variability in a population. Reduced genetic variability in a small population is especially threatening because the chances of population surviving environmental changes get slimmer. This is because natural selection acts of genetic variability to get a population to adapt to changes in the environment.
The dominant trait, think of it like big R dominating the smaller r.
Answer;
The above statement is true
Explanation;
-Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Its velocity is changing not because the magnitude of the velocity is changing but because its direction is.
The answer is forest fires.
