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.

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....

Answer:

The correct answer is temperature.

Explanation:

I took the test.

The density-independent limiting factor is any force that affects the size and population, temperature, hence option b is correct.

In ecology, a density-independent factor is any force that has an impact on the size of a population of living creatures regardless of the population's density.

This term is also known as a limiting factor (the number of individuals per unit area). These density-independent causes include nutritional or food scarcity, environmental contaminants, and harsh weather.

Natural catastrophes, seasonal patterns, odd weather, and human activities are density-independent influences.

Therefore, in addition, catastrophes like fires, temperatures, and storms can have an effect on population increase, hence option b is correct.

Just like the dinosaurs

Answer:

Then I will probably cry. No I'm kidding, well, not kidding. Whatever. If lynxes went extinct there would probably be a large gap in the food chain, resulting in several other extinction events, and possibly overpopulation. Rabbits would likely thrive, seeing as they are the lynxes main food source, and the rabbits would eat too many plants, causing there to be no plants for the other animals in that environment. Many issues would be caused, and I will probably have a mental episode, because lynxes are my FAVORITE animal. Beautiful, cunning, and an apex predator. By far the most amazing animal on earth.

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.

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.

Homeostasis is a self regulating process that maintain a stability of internal body with respect to the changing external environment which ultimately maintain a steady state of the living system.

It maintain body homeostasis by regulating body temperature, blood pH, blood glucose level,  sodium, potassium and calcium ion concentrations.

Three mechanisms are involved in homeostasis such as Effector, Receptor, Control Center.
