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.

Cell size and shape are important factors in determining the rate of diffusion. Think about cells with specialized functions, such as epithelial cells that line the small intestine or plant root hairs. What is the function of these cells? Sketch the shape of these cells. How does the shape of these cells relate to their function?
Answers
Answer:
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.

A. releasing H+ to a solution when acids are added.
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.

Answer:
[tex]\boxed {\tt B. \ Photosynthesis \ creates \ glucose \ using \ energy, \ a \ gas,and \ a \ liquid}[/tex]
Explanation:
Glucose is made in the process of photosynthesis. It is used in cellular respiration, but not made. So we can eliminate choices C and D.
Now, let's analyze the photosynthesis equation so we can pick between A and B.
6CO₂+6H₂O+light energy ⇒ C₆H₁₂O₆+6O₂
A gas (carbon dioxide), a liquid (water) and energy are used to make glucose and oxygen.
No solids are used, so we can eliminate choice A. We are left with choice B. Photosynthesis creates glucose using energy, a gas, and a liquid.

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 locationExplanation:
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.

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?
Answers
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

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.

Answers
Answer:
16. Carbohydrates
17. Lipids
18. Carbohydrates
19. Carbohydrates
20. Lipids
21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.
