Answer:

In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:

The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration

The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane

In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.

Answer:

Tomatoes are triggered to turn red by a chemical called ethylene. Ethylene is odorless, tasteless, and invisible to the naked (human) eye.

Explanation:

Answer: As the tomato ripens, its color starts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesizes a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant color of the tomato, red

Explanation: Microscopes often use a mirror to direct available light to the specimen platform, so if you don't have enough light it will be difficult to view your specimen and can cause eye strain.

Microscopes may malfunction if stored or used in a location exposed to direct sunlight. Also, direct sunlight may harm the observer's eye if it enters a microscope through the reflector.

For optical microscopes:

Light from outside is sent to the reflective mirror to illuminate the sample. Direct sunlight must be avoided. ... This inexpensive and readily available lamp, also called an incandescent lamp, is widely used in optical microscopes.

The evidence that was put forward by Richard Wrangham to support his hypothesis that intraspecies aggressiveness was common in the last common ancestor of chimpanzees and humans is that chimpanzees conduct raid against individuals in neighboring territories.

Intraspecies aggressiveness is the form of aggressiveness between humans beings and other animals. They're a threat of action that brings about harm.

Richard Wrangham put forward evidence to support his hypothesis that intraspecies aggressiveness was common as he stated that chimpanzees conducted raid against individuals in neighboring territories.

According to the properties of osmosis, the cell will burst. So the correct option is C.

Osmosis is the spontaneous diffusion or flow of water or other solvents over a membrane that is semipermeable and prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.

Previous researchers have conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposing directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process.

The Dutch-born chemist Jacobus Henricus van 't Hoff demonstrated in 1886 that osmotic pressure varies with concentration and temperature roughly as it would if the solute were a gas occupying the same volume if the solute is so dilute that its partial vapor pressure above the solution obeys Henry's law (i.e., is proportional to its concentration in the solution.

Therefore the correct option is C.

The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.

In atherosclerosis, the affected anatomical feature is the artery. This is a condition that causes the obstructions of blood flow through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to heart attacks, among other consequences.

In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the immune system to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, stiffening and disrupting the communication of the nerves with the central nervous system.

Answer:

diffusion

Explanation:

The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.

Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.

Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.
