True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.

2. If 10% of the bases in a molecule of DNA are adenine, what is the ratio of adenine to guanine in the same
sertanlavr [38]

Answer: Option D) 1:4

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.

Then, 10% + 10% + C + G = 100%

20% + C + G = 100%

C + G = 100% - 20% = 80%

Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%

Ratio Adenine to Guanine is 10% to 40%

or 1:4 in simplest form
