The question is incomplete as it does not have the tiles which has been presented in the attachment.
Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
Answer:
• But they do not happen every full moon night because Earth's orbit around the sun is not in the same plane as the moon's orbit around the earth. Eclipse occur only if the the sun, the earth and the moon come to lie in a straight line.
Explanation:
• False.
Answer:
A. Alternative mRNA Splicing
Explanation:
The primary transcript of eukaryotes has introns and exons. The post-transcriptional modification includes splicing of introns and joining of exons to form a mature mRNA.
A single gene can specify two or more related proteins due to the process of alternative splicing of mRNA wherein exons are removed and joined in various combinations which in turn serve as the template for different proteins.
For example, if a primary transcript has 7 exons, the mature mRNA may have all 7 exons or some of them in various combinations. The resultant mRNAs with different combinations of exons would specify different proteins.
