Needs answers for both thanks

Answers

Answer:

The answer to the first question is A.

The answer to the second question is False.

Explanation:

An animal's fur color is like a human's skin color. If both parents are the same color, the children will have the same. If it is a mix, it will either mix the colors or just be one. So as both mice are white colored, the offspring will be white furred too.

Now for the second question. Once again, just like humans, mice inherit traits about the same. The traits from the parents will most likely carry on. There is also times where a new trait comes in. This is not very common but it happens occasionally.

why are advantageous traits more likely to be passed onto offspring

Answers

Answer: Variations of traits causes those better suited to the environment to survive and reproduce. ... Why are advantageous traits more likely to be passed onto offspring? Because they are more likely to survive and reproduce.

A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?​

Answers

Answer:

Because they don't have fertilizer.

Explanation:

Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.

A strand of DNA, GCT-AAT-GAT, unzips to make mRNA. What is the sequence of the complementary mRNA strand?

A. UAG-CCG-UCG
B. CGT-TTA-CTA
C. CGA-UUA-CUA
D. GCT-AAT-GAT

Answers

Answer:

C. CGA-UUA-CUA

Explanation:

The deoxyribonucleic acid (DNA) is a double helix molecule which is composed of four letters or 'nucleotides': guanine (G), cytosine (C), adenine (A) and thymine (T). The base-pair rules state that in the DNA double helix, G always pairs with C, while A always pairs with T. Moreover, during transcription, a base named uracil (U) replaces T in the resulting RNA sequence. Therefore, in this case, the complementary sequence (i.e., antisense strand) to the mRNA sequence is CGA-UUA-CUA.

Air tends to flow faster over ______ formations.
a. sheltered
b. medium-sized
c. shorter
d. taller

Answers

Answer:

d. taller

Explanation:

The air tends to flow faster over taller formations. Therefore option D is correct.

When air encounters different formations or obstacles, it can affect the speed and behavior of the airflow.

Taller formations, such as tall buildings, mountains, or cliffs, can create an obstruction in the airflow. When air encounters a taller formation, it is forced to flow up and over the obstacle.

As a result, the airflow can accelerate on the windward side of the formation and create faster wind speeds. This phenomenon is known as an acceleration zone or an area of increased wind speed.

Therefore, the correct option is d. taller formations. Taller formations can cause the air to flow faster due to the presence of acceleration zones or areas where the airflow is forced to speed up as it interacts with the obstacle.
