The hedgehog ligans activate it
<span>Human genetic disorders can be caused largely by the change of the DNA sequence from its normal sequence. This can also be caused by a monogenic disorder, a mutation in a gene. So the best answer to this question would be letter B since nondisjunction causes chromosomal abnormalities.</span>
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

Explanation:
Answer:
The three R's – Reduce, Reuse and Recycle – represent the best strategy for conserving non-renewable oil, coal and natural gas. ... Increasing the reliance on renewable energy sources, such as solar, wind and geothermal generators, can also help conserve the dwindling supplies of fossil fuels that remain in the ground.
