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

I'm almost positive it is tissue because all organ have tissue but most have muscles, blood, veins
The end result of cytokinesis indicates the two cells with identical copies of DNA arise from a single parental cell.
<h3>What is Cytokinesis?</h3>
Cytokinesis may be defined as the process of separation of the cytoplasm at the end of mitosis.
Cytokinesis is the phase of mitosis which involves the overall division of cytoplasm and the construction of two copies of cells with identical DNA content.
It occurs after the process of karyokinesis, which results in the formation of two daughter cells from a single parental cell.
Therefore, it is well described above.

With less chlorophyll the cells would be less capable of performing photosynthesis, and because of this, the cells would produce less glucose as a product. Furthermore, if all chlorophyll was lost, the plant would die.
The independent variable in the hypothesis of an observed increased in sea turtle sickness once an increase in red tide can be seen would be the increase of red tide.
The reason for this is that red tide increases or decreases will happen independently of the amount of sea turtle sickness - therefore increasing sea turtle sickness will be dependent on the first variable. (independent one).
