Answer 3

The process by which a modified stem or root of a parent plant grows offspring that remain attached is called vegetative reproduction.

Answer 5

Without external forces, the third generation of a bacterium and the original parent cell will have approximately 100% matching DNA sequences. Bacteria reproduce asexually through binary fission, which results in offspring that are clones of the parent cell.

Answer 6

An established bacterial community is exposed to a dark environment for several days. Bacteria that require light to reproduce will show _________ compared to bacteria that do not require light to reproduce. (1 point)
Responses

lack of growth
lack of growth

uncontrollable growth
uncontrollable growth

more growth
more growth

the same amount of growth

Answer 7

Bacteria that require light to reproduce will show lack of growth compared to bacteria that do not require light to reproduce when exposed to a dark environment for several days.
