What do you mean by ecosystem?

An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are interconnected through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into the plant tissue.

The term "ecosystem" was first used in 1935 in a publication by British environmentalist Arthur Tansley. The term was coined by Arthur Roy Clapham, who coined the word at Tansley's request.

The main ecosystem types  are forest, desert, rainforest, grassland, tundra, savanna, and mountain ecosystems.

What are three possible long-term consequences of two species occupying the same niche?

Answers

Answer:

one will become extinctone/both will adaptone will migrate to a new location

Explanation:

An ecological niche is the role species has in its environment. This includes how it survives, reproduces, finds shelter, and obtains good. It includes all its interactions with both biotic (living) and abiotic (non-living) factors.

When species occupy the same niche, it means they are competing for the same resources. This is not sustainable. Eventually, one of three things are likely to happen:

one species will die out (become extinct) because they are being outcompeted by the more successful species, and will struggle to survive without adequate food and sheltereither one or both species will have to adapt to occupy another similar niche by, for example, exploiting a new food source in the area.either one or both species will have to migrate to a new area to occupy a different geographical area and new resources.

The species that is being excluded from the niche can either adapt in the long term to occupy another similar niche, migrate to a new area, or it can die out.

Answer: The species that is being excluded from the niche can either adapt in the long term to occupy another similar niche, migrate to a new area, or it can die out.

Humans often invade spaces that were once isolated, such as beaches, affecting how animals produce offspring. Humans are overtaking the natural habitat of sea turtles, reducing the space where they deposit their eggs. Females will only deposit eggs on the land where they were hatched, and if that is taken from them they will never lay eggs. Which is NOT a step humans can take in helping sea turtles? A) Respect the areas that have been roped off for turtle eggs B) When turtle eggs are found, move them to a safe place C) When boating, try to avoid places where turtles swim and eat D) If found, do not disturb eggs or sea turtles that are laying eggs

Answers

Answer:

B) When turtle eggs are found, move them to a safe place.

Explanation:

Based on the given article, we can learn that human encroachment has decreased the private lands/ spaces for animals to reproduce properly. One such case is that of the sea turtles. As the females only "deposit eggs on the land where they were hatched", it is important to keep them safe and undisturbed.

Therefore, one step that isn't helping the turtles is to move the eggs to a safe place. This is because female sea turtles "will never lay eggs" if their eggs are ever taken away from the original place they were laid at.

Thus, the correct answer is option B.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?

A: it would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.

B It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.

C Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.

D Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Answers

Answer:

D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Explanation:

According to this question, some types of syrup contains an entirety of glucose molecules. Hence, eating a syrup like this will have no effect on the person's ability to exercise, however, since glucose is the simplest unit of carbohydrate food sources, it gets digested easily.

Originally, glucose molecules, which are products of digestion, enter into our cells to be used to synthesize energy. However, for a syrup already made up of glucose molecules, the digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the simplest form of carbohydrate, which is digested by the human digestive system. The syrups that are completely made of glucose molecules will not affect the person's ability to exercise.

The correct option is:

Option D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the primary source of energy in all living organisms.

If a person is consuming a syrup made up of glucose molecules, it will not affect the ability of a person to exercise.

The glucose is present in simpler form, which will be directly absorbed by the cells to carry out functions and yield energy.

Thus, the digestive system will work normally because the cells are supplied with glucose and it won't affect the ability of the person to exercise.

Therefore, option D is correct.

B. donating H+ to a solution when bases are added.

C. accepting H+ from a solution when acids are added.

D. both donating H+ and accepting H+.​

Answers

Answer:

Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).

Explanation:

A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.

The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.

The other options are not correct because:

    A. Buffers do not release H+ into a solution when acids are added, but accept them.

     B and C.  Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

Epithelial cells are the protective cells. They form the outer covering of the body surface which protects the body from any external danger.Cuboidal epithelial cells, as their name suggests, are shaped like cubes. These are typically found in tissues that secrete or absorb substances, such as in the kidneys and glands. Columnar epithelial cells are long and thin, like columns. These are usually found in places that secrete mucus such as the stomach.
