Answer:
The correct answer will be option-B
Explanation:
The environment of the stomach is acidic in nature maintaining value less than seven as it kills the microbes and helps activate the pepsin to digest the proteins.
The acidic nature of the gastric juice does not affect the stomach as the mucosa layer of the stomach secretes mucous and the if the cells get affected then the cells are repaired by the process of mitosis taking in the epithelial cells.
Thus, Option-B is the correct answer.
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
The answer is: The <span>exocrine structure that is involved in the digestion of fat is </span>liver.
<span>>The liver plays an vital role in the digestion and processing of proteins, fat and sugar.
</span><span>>The liver plays a significant role in fat digestion as well as the production of fats needed for the function of different organs of the body</span>
The statement that organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to their offspring is false. Organisms pass their traits and adaptation abilities to their offspring. These organisms have also characteristics that are advantageous for reproduction in a specific environment and leave more offspring in the next generation. The process is called natural selection.
Answer:
E. 1/600
Explanation:
Hint:
The probability of fixation of a new neutral mutation is 1/(2N)
Given N as 300
= 1/(2×300)
=1/600
Therefore,
1/600 gives a sure fixation of one allele from the large population
