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
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.
The thermal energy of matter depends on its _________. a mass. b temperature. c number of particles. d all of the above.

Needs answers for both thanks
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.

How does the Earth's atmosphere interact with the sun's rays? A. The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth. B. The sun is outside of the atmosphere and doesn't interact with it at all. C. The atmosphere deflects the sun's poisonous elements. D. None of the above
Answer:
The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth
Explanation:
This is because the atmosphere also interacts sun radiations that comes in contact with through a process called molecular scattering. Light rays are very minute and there are alot of small molecules that float in the atmosphere and when light comes from the sun, the smaller molecules scatter the Ray's and it warm the Earth. Huge numbers of small molecules float in the atmosphere. There is a layer called ozone which absorb sun radiations.

Present one example of a human activity that threatens
ecosystems and biodiversity.
Answer:
One example is overpopulation. Meaning the more people there are in a place, the more room there needs to be. This then leads to deforestation, destroying animals habitats forcing them to leave. The more animals that leave, the less animal diversity there is.
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?
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.

Explanation:
John was able to move a small plastic ball by blowing on it. How does this show that matter is made up of particles?
The air coming out of John's mouth fills up the plastic ball.
The air particles change the shape and size of the plastic ball.
The ball is made up of particles that move and cause the ball to move.
The particles of air coming out of John's mouth pushed the ball.

In the diagrams of mitotic cell division shown, which structure is present in diagram B but in diagram A?
-centriole
-cell plate
-cell membrane
-cytoplasm
Answer:
-cell plate
Explanation:
Diagram A is an animal and diagram B is a plant cell. When dividing through mitosis plant cells form a cell plate during the mitotic phase. However, cell plates are not found in animal cells, as they do not have cell walls. Therefore, the answer must be cell plate.
