Answer:
The correct answer is - Cyanobacteria; Horizontal gene transfer
Explanation:
According to the endosymbiotic theory it is believed that the eukaryotic plastids (mitochondria and chloroplasts) have developed from symbiotic bacteria, such as cyanobacteria and alpha-proteobacteria.
During this symbiotic process, some genetic material may have been move in between the symbiotic counterparts in a process called Horizontal gene transfer or lateral gene transfer.
thus, the correct answer- Cyanobacteria; Horizontal gene transfer
5) A. Half the density of the original block. (Because you're cutting it in half, each would be the same)
6) 250ml = 0.25 liters
1ml = 0.001 liter
250ml = 0.25 liters
