Facilitated diffusion is the process by which molecules move across the plasma membrane with the aid of membrane proteins like channels and carriers. These molecules move down a concentration gradient, which gives them the potential to diffuse into (or out of) the cell.
Passive transport is a subset of facilitated diffusion. Because the solution is travelling down the concentration gradient, assisted diffusion is still passive transport even when it incorporates transport proteins. The cell membrane can easily be traversed by small, nonpolar substances.image outcome.A case of enhanced diffusion is glucose transfer. The lipid bilayer of the membrane prevents glucose from passing through since it is a big, polar molecule. In order to pass through, it requires carriers known as glucose transporters.

Answer: c.The caterpillars gain energy directly from the orchids.
A food chain is a linear sequence of transfer of food and energy when one organism is consumed by another organism. A food chain maintains the balance of abundance of organisms forms on earth as one organism is fed by the other.
In the given food chain, the caterpillars gain energy directly from the orchids is the correct option because the population of caterpillars eat upon the orchid plants. The food in the form of orchid plants is necessary for obtaining energy by the caterpillars.
Answer:
~ Halon gas
Explanation:
~ Halon is a liquefied, compressed gas that stops the spread of fire by chemically disrupting combustion. ... Traditionally, to stop a fire you need to remove one side of the triangle - the ignition, the fuel or the oxygen. Halon adds a fourth dimension to fire fighting - breaking the chain reaction.
Answer:
it's the second one
Explanation:
because we hear extra noise
