What are the 3 principles of heredity that Gregor Mendel discovered?

1 answer:

7 0

<span>Based on the information shared by the experiments of Gregor Mendel, the statement “traits are passed from parents to offspring independently of one another” is actually a theory and not a hypothesis or observation. It cannot be a hypothesis as it is already tested and proved. Hypothesis is something that has not been proved. An observation is something that has been observed, but never proved. Gregor Mendes proved this theory or hypothesis in the laboratory and so it is surely a theory. </span>

A large forest fire burns in Canada, dropping black carbon on Greenland. Which of the following is true

klemol [59]

In the case of the large forest fire burns in Canada, the option that is known to be true is option B: . The Greenland glaciers will melt faster.

<h3>How do wildfires affect glaciers?</h3>

A new study has shown that the exposure of glaciers to any kinds of wildfire smoke can lead to the glaciers melting faster than normal.

Note that this often affects mountain runoff that gives the main freshwater resources for all of life downstream.

Hence, In the case of the large forest fire burns in Canada, the option that is known to be true is option B: . The Greenland glaciers will melt faster.

A large forest fire burns in Canada, dropping black carbon on Greenland. Which of the following is true?

A. The Greenland glaciers will be protected from melting as the ash will insulate the ice.

B. The Greenland glaciers will melt faster.

C. The black carbon will not affect the Greenland glaciers.

D. It is unknown as to what effect the black carbon would have on the Greenland glaciers.

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).

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

Nitrogen makes up a significant part of which class of biological compounds?

disa [49]

Nitrogen is the most important constituent of the amino acids, which combine together to form peptides and proteins. Proteins are the building blocks and are involved in structure, functioning and regulation of various body parts. They are also present in the form of enzymes and are crucial.
