The appropriate response is all of the above. Punctuated equilibrium is a hypothesis in developmental science which suggests that once species show up in the fossil record they will end up plainly steady, demonstrating minimal transformative change for the greater part of their land history. This state is called stasis.
Both parents must be carriers, which means they have the heterozygous gene (one uppercase letter & one lower case letter). They will still carry that mutated gene (because they have a lower case letter), and their offspring will have a 25% chance of getting a recessive disorder. The percentage is low but still possible.
Answer:
the rate of change of velocity with time is called acceleration.
it can also be defined as the increase in velocity per second.
The S.I. unit of acceleration is meter per second square or ms−2.
formula; a = Δv / Δt
where a is acceleration,
Δv is the change in velocity,
and Δt is the amount of time it took for that change to occur.

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
a. inheritance of natural variations
b. inheritance of acquired characteristics
c. natural selection
d. survival of the fittest
Inheritance of acquired characteristics. Thus, option "B" is correct.
<h3 /><h3>What is inheritance of acquired characteristics?</h3>
For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.
Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution
