What happens to a snail/slug if you pour salt on it? why would this happen?
Answer:
When you pour salt on a snail/slug the water is very quickly pulled out of the cells of the snail's body by a process called osmosis. As it dries out, the snail's body produces a slimy substance to protect itself. The bubbling comes from the slime and air being forced out of the snail's body as it shrivels up. If enough salt is poured on the snail it will die of dehydration very quickly.

How does surface area describe a cell?
Answer:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.

Answer:
B. exponential growth.
Explanation:
Since the conditions are ideal and the reproducing organisms increase in numbers with every generation this means that it is exponentially growing. It can't be carrying capacity. It is not a logistic growth. And they don't have competition here so it can't be competition.

In an experiment, a scientist isolates mitochondria from living cells and suspends them in two different buffered solutions. One solution is maintained at pH 4, while the other solution is maintained at pH 9. The
scientist finds that mitochondria in the solution at pH 4 continue to produce ATP but those in the pH 9 solution do not
The results of the experiment can be used as evidence in support of which of the following scientific claims about mitochondrial activity?
Mitochondria in a cell free environment are unable to convert thermal energy into ATP.
The electron transport chain pumps electrons from the cytosol to the mitochondrial matrix,
CATP production in mitochondria requires a hydrogen ſon gradient that favors movement of protons into the mitochondrial matrix.
D
ATP synthase molecules change their orientation in relation to the proton gradient across the mitochondrial membrane.
Answer:C
Explanation:
The scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
Cellular respiration is defined as a group of metabolic reactions by which cells can generate ATP (the energy coin of the cell), by using oxygen and the energy released in the chemical bonds of foods (e.g., glucose).Cellular respiration has three main types of reactions: glycolysis, the acid citric cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and oxidative phosphorylation occur in the mitochondria.During oxidative phosphorylation, the movement of electrons through a series of carriers is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.Subsequently, this proton (H+) gradient is then used to generate ATP by using an ATP synthase.In conclusion, the scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).

Answer:
Proteins
Explanation:
Enzymes are an example of a class of organic compounds called proteins.
PROTEINS:
Proteins are one of the four major biological molecules in nature (others being carbohydrates, lipids and nucleic acids). Proteins play vital roles in living organisms, which includes regulating biochemical reactions, repair of structures etc. Enzymes are biological catalysts that helps to regulate the rate of a reaction. Enzymes are proteinous in nature i.e. they are made of proteins.

Petroleum.
Explanation:
I was also thinking natural gas but petroleum has had more of an influence on transportation and has been used more.
Answer: D. Petroleum
Explanation: Petroleum, or crude oil, is another fossil fuel that has had a significant influence on human activity. Petroleum is a liquid found beneath Earth's surface. It can mined or drilled and refined into products including gasoline and diesel oil. It is the largest source for energy consumption in the United States. Hope this helps! ^_^
Why is there Cholesterol in your cell membrane?
Answer:
Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.
