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.

Discuss how the properties of water help Earth support life.
Water Property:
Importance to Life:
Polar molecule:
Hydrogen bonding:
Cohesion:
Adhesion:
Surface Tension:
Temperature Moderation:
Low density of Ice:
Universal solvent:
Answer:
One of water’s important properties is that it is composed of polar molecules. The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen. Thus, it is more likely that a shared electron would be found near the oxygen nucleus than the hydrogen nucleus. Since water is a nonlinear, or bent, molecule, the difference in electronegativities between the oxygen and hydrogen atoms generates the partial negative charge near the oxygen and partial positive charges near both hydrogens.
Explanation:
As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids. A polar substance that interacts readily with or dissolves in water is referred to as hydrophilic (hydro- = “water”; -philic = “loving”). In contrast, nonpolar molecules, such as oils and fats, do not interact well with water, as shown in. These molecules separate from it rather than dissolve in it, as we see in salad dressings containing oil and vinegar (an acidic water solution). These nonpolar compounds are called hydrophobic (hydro- = “water”; -phobic = “fearing”).
The properties of water help Earth support life helps in various ways. Most of the role of the water in supporting life is because of its molecular structure which causes its specific properties.
Water is a simple molecule made of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom.
Polar molecule: The charge difference between the positive charge on one side and the negative charge on the other side form an asymmetrical molecule called a polar molecule that interacts with different molecules. Hydrogen bonding: Due to hydrogen bonding water has various life-supporting properties by the interaction of various molecules. Cohesion: water molecules attract other water molecules in a property called cohesion that plants take up water at their roots and it affects boiling point regulates body temperature of animals. Adhesion: Attraction to other molecules called adhesion that helps in binding with different types of molecules Surface Tension: surface tension of water is similar to the cohesion Temperature Moderation: water's heat capacity or specific heat prevent immediate temperature changes Low density of Ice: helps ice to flow on water not to immerse. Therefore life under the ice can be maintained. Universal solvent: makes water dissolve with other molecules and make a life-sustaining force that helps cells transport and use substances like oxygen or nutrientsThus, water is essential for supporting life and survival.

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.

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.

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.
