Answers
Option C, polar covalent bond
It's between polar compounds
The weak, electromagnetic bond between polar molecules is polar covalent bond. Thus, option C is correct.
What is covalent bond?A covalent bond is defined as a chemical bond that includes the sharing of electron pair between atoms.
The pair of electrons are know as bonding pairs and the stable balance of attractive and repulsive forces between atoms.
The properties of covalent bond are mentioned below:
The covalent compounds have low melting points and boiling points.
The covalent compounds do not contain electricity.The covalent compounds are having lower enthalpies of vaporization and fusion.
The covalent compounds are easily catches fire and are more flammable than ionic compounds.The covalent compounds are very soft and flexible.
The physical properties of covalent compounds are that they have lower melting points and electrical conductivity.
Therefore, the weak, electromagnetic bond between polar molecules is polar covalent bond. Thus, option C is correct.

Answers
Answer: The cell membrane of a living plant cell ( selectively regulates the passage of substances into and out of the cell (option D). Explanation: The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.

Answers
Answer:
Explanation:
attempted to control their population growth
The fact that people have historically prioritized short-term benefits above long-term sustainability is a significant factor in how severely humans have impacted the ecosystem.
Thus, human actions like deforestation, pollution, overfishing, and the burning of fossil fuels have historically been motivated by short-term economic or resource requirements without taking the long-term effects on the environment into account.
The stress on ecosystems and natural resources has grown due to population expansion and rising demand. Unsustainable practises, insufficient regulation, and a lack of awareness have all contributed. To solve these problems, we need to adopt more environmentally conscious behaviors by raising public knowledge of environmental issues.

Answers
Answer:
I would go with B:
The body must maintain homeostasis so that the internal environment stays the same if the outside
Homeostasis is the process of a state of steady internal, mental, chemical, and physical conditions of the body.
The correct answer is:
Option B. The body must maintain homeostasis so that the internal environment stays the same if the outside environment changes.
Homeostasis can be explained as:
It is the self-regulating process in which the body tends to keep the internal, physical, and chemical conditions of the body in a steady and equilibrium state. It generally refers to the stable internal conditions or maintaining the steady phase of the body with respect to changes in the environment. Sweating is one of the processes in which the body tends to maintain homeostasis by releasing excess heat in the hot climate.
Thus, the correct answer is Option B.

How does the property of cohesion make farming possible?
Answers
Answer:
cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces to make the crops grow faster
Explanation:
Answer:
Cohesion is the forces holding water molecules together. This concept was covered when talking about properties of water and capillary action. You may remember capillary action is like when you have a little bit of water in the bottom of your cup but the water in the straw is a little bit higher than the water in the cup. Because water is polar - meaning it has a somewhat negative end and a somewhat positive end - it is attracted to other water molecules and other substances, such as the straw.
Cohesion
Now, you may be asking yourself: what does a straw have to do with xylem? Well, just like the water moving up the straw, water moves up xylem. The movement of water in plants is from the roots up through the shoot and out the leaves. Part of the reason for this movement of water is cohesion. The water molecules within the xylem tend to stick together, which allows them to help pull other water molecules up through the xylem - even against the flow of gravity.
When water is moving through the xylem, it is moving between different vessels or tracheids. It is very important that these elements are tightly held together because if there are air bubbles, the effects of cohesion are diminished. That is, if air bubbles get into the xylem, the water will no longer move up through these tubes. We can relate this idea back to our straw. If you have ever had a straw that has even a tiny hole in it, you know that it is very hard - even with the aid of suction - to get the water through the straw and up to you. This is what happens if air bubbles get into the tubes of the xylem.
So , indirectly cohesion helps in farming through xylem....

What happened to the cheetahs?
Answers
Answer:
Explanation:
The chief threats to the cheetah's existence are loss of habitat, poaching and hunting (their hide and trophies can command top dollar), and getting shot by livestock farmers. Decline of gazelles, wildebeests, impalas and other preferred prey species (also due to hunting and habitat loss) is a factor, too.
There are various subspecies of cheetah. So the cheetah's disappearance would have differing effects in each case. In general terms, however, the cheetah is a predator and hunter at the top of the food chain, so its disappearance would impact its prey and so on down the line.

5. What do porifera use their flagella for?
(1 Point)
O swimming
O eating
reproducing
Answers
Answer:
Porifera use their flagella to eating.
Explanation:
Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.
Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.
The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.
The other options are not correct:
Porifera is immobile, so the flagella do not participate in swimming.Flagella do not participate in the reproductive process of marine sponges.What are the advantages and disadvantages of gene therapy?
