True or False: Earthquakes, Volcanoes, mid ocean ridges, deep sea trenches all occur at the edge of the plates or boundaries

Svetradugi [14.3K]

Answer:

so i wanna say ... true?

Explanation:

Most of the Earth's geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. At a convergent boundary with at least one oceanic plate, an ocean trench, a chain of volcanoes develops and many earthquakes occur.

inn [45]

All macromolecules have carbon atom and the hydrogen atom.

<h3>What are macromolecules?</h3>

The term macromolecules refers to the molecules that are composed of smaller units. These smaller units are called monomers. The macromolecules that we are concerned with here are the macromolecules that could be found in the human body.

The biological macromolecules are often very large as we can see. This is because the number of units that are joined to form the macromolecules are usually very much. There are thousands of monomer molecules that are joined together to give proteins, lipids, carbohydrates and the nucleic acid macromolecules.

All the macromolecules have the carbon atom and the hydrogen atom. These are found across all the macromolecules. The carbohydrates are reducing sugars thus they contain the carbonyl bond. The carbonyl group is absent in lipids, nucleic acids, proteins, and amino hence they do not undergo carbonyl reduction reactions.

Deciduous trees, such as maple and elm trees, regularly drop their leaves in a response to a change in the environment.

igor_vitrenko [27]

The correct answer would be C.seasonal changes in the amount of daylight. Since leaves require sunlight in order to perform photosynthesis to keep the tree alive, when seasonal changes occur where there is not enough sunlight throughout the day, trees go dormant for the season until conditions are right.

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).

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