Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

What is the region that is located between Mars and Jupiter and is labeled A
in the illustration?
Solar System
А
O A. The Kuiper belt
OB. The asteroid belt
O C. The terrestrial belt
OD. The comet belt
Answer:
asteroid belt
Explanation:
region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.

Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?
A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.
Answer:
C!!
Explanation:
The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
Connect the importance between meiosis and the process of sexual reproduction. Is it possible to survive without your reproductive system? Explain.
Answer:
This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation. To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.
