Which of these is an example of nonpoint-source pollution?

Answer:

The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.

Explanation:

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins.

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Answer:

a. the climate

Explanation:

Comets are small bodies that go around/orbit the sun. A comet can also pack more damaging force than even an asteroid of the same mass. The dusty particles combined with ice and water, become the amazing beginning of a Comet.

When a comet or comets come within a certain distance of the Sun, they sublimate, which is another word for going from a solid-state to a gas without ever becoming a liquid.

Answer:

Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

Explanation:

Answer:

Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.

Answer: The answer is C

A prokaryotic cell usually lack a well defined nucleus. The correct option is C.

A prokaryotic cell is one that lacks a true nucleus and membrane-bound organelles.

The prokaryotic cell is the foundation of organisms in the domains Bacteria and Archaea.

Thus, the correct option is C.

Answer:

smooth and involuntary

Two layers of smooth muscle form the small intestine. The outermost layer is the thin, longitudinal muscle that contracts, relaxes, shortens, and lengthens the gut allowing food to move in one direction. The innermost layer is a thicker, circular muscle.

Also smooth muscle is not under our control so is called involuntary

Answer:

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur

Answer:

water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
