Answer:
Movement of particles from a region of high concentration to a region of low concentration
Explanation:
- Diffusion can be defined as the movement of particles from a region of high concentration to a region of low concentration.
- Diffusion is a special type of diffusion that involves movement of solute molecules from a region of a high concentration to a region of high concentration until equilibrium is achieved.
- Diffusion is a passive transport of particles, which means it does not involve use of energy in the form of ATP like the case of active transport.
Answer:
Microbes are decomposers. They eat all dead and decaying material.
Answer:
Beryllium's atomic number is 4
Explanation:
<u>Reason</u>
- Beryllium has 4 protons, 4 neutrons, and 4 electrons.
- This makes it a nuetral atom meaning that it contains an equal amount of protons and electrons
- This means that beryllium has a atomic number of 4
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.
