Answer:

The correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.

Explanation:

Bacterial cell wall is made up of peptidoglycan which contains NAG and NAM units joined together by β(1-4) glycosidic linkage but the cell wall of archaea are different from the bacteria and called pseudo-peptidoglycan.

The cell wall of archaea is also called pseudomurein which is also composed of two units, N-acetylglucosamine and N-acetyltalosaminuronic acid and these two components are joined together by β (1-3) glycosidic linkage which is different from linkage in bacteria.

Therefore the correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.

If two intermediate-colored chickens together produced 100 chicks, how many would you expect to be black?
sergiy2304 [10]

Answer: 25 of the chicks will be black

Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.

Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.
