How many cells have been killed by the virus in this image?
A. 7
B. 13
C. 20
D. 29

The answer is A.7

Explanation:

(Dead cells are in black) (Infected are potato color with green inside them) (Healthy cells are potato color without green)

First, 13 is wrong because there are not yet 13 dead cells

Second, 20 is wrong because there are no 20 dead cells

Third, 29 is wrong because there are no 29 dead cells

So 7 is the only answer and it is correct

Hope this helps

b because they naturally adapt to their environment plz mark brainliest

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
