<u>Answer:</u>
Photosynthesis and respiration are so interrelated with each other that one’s product are used as another’s reactant.
<u>Explanation:</u>
- Photosynthesis is a process used by organisms to convert 'light energy' into 'chemical energy', which is used as a source of energy for the organism.
- Respiration is a process in which glucose and oxygen is used to create ATP for the survival of the organism.
- During photosynthesis 'water and carbon dioxide' reacts in presence of light to create oxygen and glucose.
- Without photosynthesis and respiration life ceases to exist on earth.
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
