Answer:

The correct answer is A) Have diverse cell wall compositions

Explanation:

Both bacteria and archaea comes under prokaryotes because they both lack a membrane-bound nucleus. The difference between archaea and bacteria is in their cell wall composition.

The bacterial cell wall is made up of peptidoglycan and the archeal cell wall is made up of pseudo-peptidoglycan. In bacteria, peptidoglycan contains N acetyl muramic acid and N acetyl glucosamine unit but in archaea, the N acetyl muramic unit is replaced by some other unit and the linkage of two units is also different in archaea. So the right answer is A.

Answer:

A) Have diverse cell wall compositions

Explanation:

The Archaea bacteria are the unicellular prokaryotes which share common features with the Eubacteria and the Eukaryotes.

Like Eubacteria the Archaea do not possess a well-defined nucleus, they reproduce by binary fission, use a variety of organic compounds as food but the difference between them is the composition of the cell wall.

The cell wall of archaea bacteria differs from that of the eubacteria as the cell wall of eubacteria contains the peptidoglycan whereas the archaebacteria do not possess peptidoglycan but a similar molecule with different sugar called pseudo-peptidoglycan.

Thus, Option-A is the correct answer.

The pancreas and the gonads are glands with double secreation. Explain why.

olganol [36]

Explanation:

Pancreas functions as both endocrine and exocrine gland. Hence, called as dual function gland or a mixed gland. Exocrine part of pancreas secretes digestive enzymes while, its endocrine part (islets of Langerhans) produce two hormones, i.e. insulin and glucagon.

A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a r

mel-nik [20]

Answer:

a) The correct answer is 1/2 or 0.5

Cystic fibrosis is a recessive disorder and her sibling has a disease but none of the parents had it. Thus, each of the parents must be the carrier of the disease, that is, both of them must be heterzygous.

So, if we cross Cc x Cc, it results in the genotype ratio of 1 (CC) : 2 (Cc) : 1 (cc)

Thus, 2 out of 4 would be the carrier of the disease.

b) 1/16

The probability of female to the carrier is 1/2

Same is the case with male partner due to the probability that he would be the carrier is 1/2

If both are carrier then, there is only 1/4 chances that the offspring will have the disease (as per cross shown above).

Now, the probability that the offspring will have the disease = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

So, $\frac{1}{2}x\frac{1}{2}x\frac{1}{4}$ = $\frac{1}{16}$

c) 1/8

The probability of female to be the carrier is 1/2

The probability male to be the carrier is 1/2

If both are carrier then, there is only 2/4 chances that the offspring will be the carrier of the disease (as per cross shown above).

Now, the probability that the offspring will be the carrier = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

$\frac{1}{2}x\frac{1}{2}x\frac{2}{4}$ = $\frac{1}{8}$

Weasels eat arctic hares which is the predator

aleksandr82 [10.1K]

The Arctic Hare's main predators are the Arctic fox, the weasel, snowy owl, and the lynx. Because hares provide food and fur for people, they are often killed by hunters. The Arctic Hare has no prey because it does not feed on animals.
