Answer:
Cheek cells lack a rigid cell wall and due to this their shape is not as well defined as a plant cell.
Explanation:
- Cell wall is the outermost structure in plant and bacterial cells.
- The plant cell wall is made up of cellulose and provide rigidity and shape to the cell.
- In animal cell, the cell wall is absent and the outermost part of the cell is the cell memrane.
- This is the reason that most animal cell lack rigidity and shape.
All of the statements above
except "most only thrive in narrow range of environments," is true
for the eubacteria. They are organisms that can be found in every habitat on
Earth. Some of these bacteria are responsible for the diseases that we contract
but they also play a large role in the Earth's ecosystems as decomposers and
heterotrophs. They have genetic structures that help them thrive and survive in
extreme environments.

Answer: don’t know really how to explain it but it’s geographic isolation
In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
Answer:
It is well-supported by evidence
