Acceleration is defined as the rate of change of velocity
Since velocity is a vector, it has both speed and direction.
So, if the object is travelling in a straight line at a constant speed, then it will not be accelerating. Both Magnitude and direction are constant.
However, if the object is travelling in a circle at a constant speed, then it'll be accelerating. An Object going in a circle is constantly changing it's direction, which means velocity is changing, so there is an acceleration caused by a net force.
Hope this Helps :)
Answer:
C. There is no genetic drift
Explanation:
A population is said to be in genetic equilibrium when the genetic variation of a population remains constant over many generations.
For a population to remain in genetic equilibrium it is necessary that external factors that disturb the equilibrium should not be present.
The external factors that are responsible for disturbing the genetic equilibrium are mutations, non-random mating, genetic drift and gene flow.
Genetic drift occurs when due to a chance event the allele frequency of a population either increases or decreases and this is usually common in small populations.
Thus, genetic drift should not occur so that the population can be in genetic equilibrium.
A centriole is a small set of microtubules arranged in a specific way
Answer:
A group of bacteria that accumulate in layers and secrete an protective extracellular material.
Explanation:
The biofilm is a natural way how the bacteria get together to survive in an ecosystem or in another living thing. They build little by little this kind of building with different layers of bacteria that secrets a polymer, this protection polymer could be useful to protect the colony or to be attach to another cell or to a tissue. In medicine and in veterinarian studies is interesting because can be useful to create a film to protect some injuries.
