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

Several species of fish and marine life eat plankton. How is that diversity important to the ecosystem as a whole?
xeze [42]
Plankton is at the bottom of a food chain. Think of a pond. Mosquito larvae are in a pond. They eat the plankton. Small fish eat the larvae. Larger fish eat those smaller fish and the chain keeps going..BUTTT it all started with the PLANKTON. Without the plankton the whole food chain would be messed up and everything would start dying.. No plankton, no larvae, no small fish..and so on..

You cross purple-flowered and white-flowered pea plants, and all offspring are purple. how come? select one:
Vaselesa [24]
To solve this problem on genetic dominance, we will need a punnet square.

Let's let P represent purple-flowered and p represent white-flowered.

We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.

       <u>P</u>     <u>P</u>
p|    Pp   Pp

p |   Pp   Pp

As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.

Since each flower has a dominant and recessive allele, they are heterozygous.

Therefore, the solution to this problem is D.
