Need help with the question in the picture

The answer is k = −11

Explanation:

f(−2)= 0

f(−2)= − 8  −  24  −  2 k  +  10  =  0

2 k = -22

and finally; k= −11

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
