False. Wetlands and estuaries require protection just like every other ecosystem.
Habitat protectionWetlands and estuaries represent some of the major ecosystems in the world. They serve as habitats for important plant and animal biodiversity as well as offer some vital services for mankind.
Overexploitation or abuse of wetlands and estuaries will lead to the loss of important species and services to mankind. Thus, protecting them will not only protect the habitats of important species but will also protect the interest of mankind generally.

Are plant cells shaped so they can stack?
Answer: Yes
Explanation:
Plant cells come in all shapes and sizes. Some are round, some are brick shaped, others look like shoe strings. The one thing they have in common is a rigid cell wall. This means that they cannot change shape very easily. The straight, strong walls give the plant cells tensile strength and allow them to stack on top of each other. This enables plants to grow upwards.

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.
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.

PLEASE HELP!! ASAP favorable adaptations are genetic mutations that
A are acquired by increased use of an organ
B improve the organism’s chances of survival
C cannot be passed on to the next generation
D reduce the organism’s chances of survival
Answer:
[B] improve the organism’s chances of survival
Explanation:
Favorable adaptation are individual better suited to survive and reproduce in their environment. Meaning that will become more and more common in the population. Which also means they increase an organism's chances of surviving or reproducing, so they are likely to become more common over time.
Basically, improve the organism's chances of survival and reproducing. As a result we can see that the best answer choices is [B] improve the organism’s chances of survival

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

(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.
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.

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.
