Answer:

The correct answer would be fermentation and peptidoglycan.

Explanation:

Anaerobic prokaryotes perform fermentation to get energy. Fermentation can be defined as a metabolic process, which includes the breaking of large organic molecules into simple molecules in the absence of oxygen.

Thus, the correct answer is fermentation.

The cell wall of archaebacteria is build of polysaccharides and proteins whereas the cell wall of eubacteria is made up of peptidoglycan molecules. Peptidoglycan is not present in the cell walls of archaea.

Thus, the correct answer is 'peptidoglycan.'

If a given population of diploid organisms contains only three alleles of a particular gene (say, W1, W2, and W3), how many diff

Ugo [173]

Answer:

The correct answer is 6 genotypes

Explanation:

The most known case is two alleles of one gene (A and a), and we know the possible genotypes formed are three: AA, Aa, aa. Therefore, for a given number of alleles n, we calculate the number of possible genotypes as the sum of integers between 1 and n.

- For 2 alleles (n=2, the sum of integers between 1 and 2): Genotypes= 1 + 2= 3

⇒ For 3 alleles (n=3, the sum of integers between 1 and 3): Genotypes= 1 + 2 + 3= 6

So, we have 6 genotypes for 3 alleles (W1, W2 and W3) and they are:

W1W1

W1W2

W1W3

W2W2

W2W3

W3W3
