Answer
Protista
Explanation
process of elimination,
doesn't belong to archaea because it doesn't live in extremely harsh environments
doesn't belong in eukarya because thats a domain
doesn't belong in protobiont, they were very primitive
They are all chromosomal mutations but if i had to choose it would be A
They produce many fish with food which is positive, but the negative impact they can have is when there are too many nutrients available phytoplankton can grow out of control, in which they will produce harmful algae blooms that are toxic and can harm sea life.
<u>Answer</u>:
An observation that would allow for identification of the cell as an animal cell rather than a plant cell would be "the centrioles migrating".
<u>Explanation</u>:
Centrioles start moving towards the opposite ends of the cell, whereas the microtubules starts moving from the centrioles and gets attached to the centromeres of chromosomes. The microtubules that have been projecting from the centrioles on opposite poles of the cell are connected to individual centromere and further form into spindle fibers. After the accumulation of chromatin into chromosomes in prophase, resulting in the breaking down of the nuclear envelope, or membrane. In case of animal cells, the centrioles present at the nucleus starts to separate and go to the opposite poles of the cell. As the centrioles transfer, a spindle is seen to be formed between them.
True organisms that can’t live in the presence of oxygen are called “facultative anaerobes.”
