Answer:
Day 10
Explanation:
If the number of bacteria increases by a factor of two each day (i.e. it doubles), it will reach 5120 by day 10. At this rate, the colony likely started with 10 bacteria on day one and doubled each day to reach 320 by day 6.
Day 6- 320 bacteria
Day 7- 320×2= 640 bacteria
Day 8- 640×2= 1280 bacteria
Day 9- 1280×2= 2560 bacteria
Day 10- 2560×2= 5120 bacteria
Answer:
The answer is B

A mutation is a change in DNA, the hereditary material of life. ... So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
When plants do not get enough nitrogen, they are unable to produce amino acids (substances that contain nitrogen and hydrogen and make up many of living cells, muscles and tissue). Without amino acids, plants cannot make the special proteins that the plant cells need to grow.
