(C) Placing plants in hypertonic environments and monitor their growth compared to plants placed in a hypotonic environment.


(D) Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.

Answers

Answer:

Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.

Explanation:

I did the quiz.

The experimental design that would provide students with information about how the presence or absence of enzymes affects organisms is as follows:

Monitor the energy level of earthworms where one group has very few mitochondria and therefore lower levels of ATP synthase.

Thus, the correct option for this question is D.

What are Enzymes?

Enzymes may be defined as biological catalysts that assist in increasing the speed of the biochemical reaction inside the body of living organisms. Such types of compounds regulate the process of biochemical reactions without being consumed in them.  

Among the options given above, the mitochondria is a type of cell organelle that produces energy in the form of ATP with the action of an enzyme known as ATP synthase.

If this enzyme is present in a normal amount, then the synthesis of ATP or energy is normal for the organism. But if this enzyme is lower than the actual level, it is found that mitochondria would not produce sufficient energy.

Therefore, the correct option for this question is D.

4. In gel electrophoresis, are the dna fragments attracted to, or repelled from the negative pole of the electric field?

Answers

In the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

What do you mean by Gel electrophoresis?

Gel electrophoresis may be defined as a technique that separates DNA, RNA, and proteins on the basis of their molecular weight.

As we all know, DNA fragments are negatively charged in nature, and hence they always move towards the positive pole of the electric field.

Therefore, in the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

Which of the following statements incorrectly describes nonspecific external immune responses?


A) The skin is a physical barrier and keeps pathogens from entering the body.

B) Nonspecific external immune responses are the second immune response against pathogens.

C) All of the statements correctly describe nonspecific external immune responses.

D) Mucus is a mechanical barrier where enzymes are used to kill pathogens.

Answers

It would be B because second immune response would be when white blood cells bind to a pathogen for the second time

Non-specific external immune responses are the first immune response against pathogens. Thus, the given statement B is incorrect.

The immune response elicited by external parts of the body are non-specific in action. These constitute the first line of defense. These include skin, tears, mucus, sebum, nasal hair, eyelashes, etc.

The skin is a mechanical barrier that prevents the entry of pathogens into the body. The skin secretes sebum which has a pH in the range of 3-5 which inhibits the growth of microorganisms.

The mucus entraps microorganisms and thus prevents them from entering inside the body. It also secretes lysozyme, which is a hydrolytic enzyme that kills the foreign invading pathogen.

How does humans affect the moth population?
How does the moth population be affected?

Answers

Answer:

Before the industrial revolution, there wasn't much pollution/soot, and the moths were mostly light colored. When humans started using machines for everything, soot coated the trees and the light colored moths were easier for birds (predators) to see. The moths became mostly dark colored, because it was better camoflauge.

Now that we have environmental restrictions, there isn't as much soot everywhere. Now moths are mostly light colored again, because the dark moths are easier to see.
