Answer: Anaerobic cellular respiration
Some prokaryotes—bacteria and archaea—that live in low-oxygen environments rely on anaerobic respiration to break down fuels. For example, some archaea called methanogens can use carbon dioxide as a terminal electron acceptor, producing methane as a by-product.

Answer:

Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:

The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:


Represent as percentage:

Waterfalls often form in the upper stages of a river where it flows over different bands of rock.
