Answer:
A and D
Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.
If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:
- Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
- The normal synthetase might be present but not in an adequate amount.
Correct answer: A). Light slows down as it moves from the air in to the water, resulting in refraction, or a bending of light.
This is because as light travels through one media it travels in a straight line, however, when it travels from one media to another media it bends, light path bends because of the phenomenon of refraction of light.
The refraction takes place only at the boundary, as the light continues to cross the boundary, it travels in a straight line.
So, as the portion of the pencil is submerged in water, the light will travel from water to air.
Hence it appears to be broken because of refraction of light. So, the correct answer would be option A.
As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.
Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.
