Answer: Option 'C' is correct.

Explanation:

Every cells change with ageing.

As cell age they tend to become larger and as the body ages it tends to have fewer cell dividing.

As the age of cells increases, cells become less able to divide and multiply.

Due to which when an middle aged or old aged person get wounded, their healing takes so much of time as compare to child because new cells do not develop easily in old age people. It takes time to develop new cell to heal their wound.

Hence, option 'C' is correct.

Answer:

option D, smaller; fewer cells dividing

Explanation:

With aging a cell's performance slows down and after a certain period of time it dies. In this way several cell die in an aging person , thereby making an organ less functional.

The number of living and functional cells in testes, ovaries, liver, and kidneys decreases markedly with aging.

As a cell dies, it shrinks and reduces in size thereby expelling liquid out of it.

Also the rate of formation of new cells reduces with progressing age.

Therefore, as a person becomes old the cell reduces their size and hence die. Also the cell division process becomes slow

Option D is correct

Reil [10]

Answer:

Enhancer sequence.

Explanation:

Enhancers may be defined as the transcription factors that are used to enhance or increase the activity of the gene. Enhancers bind with the transcription factors to regulate and increase its expression.

The mutation in the enhancers decrease the transcription of  of the other gene. These sequences lies far away from the transcription site but still known to increase the rate of transcription. Hence, the mutation has been done in the enhancer sequences.

Thus, the correct answer is option (b).

How many hydrogen atoms can bind to one carbon atom?
Damm [24]

I think that the question is not clear enough. Can you be more specific?

If your question was something like this: how many atoms of hydrogen can be around carbon, then the answer is 4. Carbon forms 4 bonds with other atoms.

Please note that carbon need not always form bonds to four atoms. A carbon could form a double bond with an oxygen and then two single bonds to hydrogen atoms. The carbon is only bonded to three atoms, but is forming a total of four bonds (1 double and 2 singles).
