Define the following:
A. Passive tranaport
B. Diffusion
C. Osmosis
D. Facilitated Diffusion
E. Active tranaport
F. Selectively permeable
G. Cellular respiration
Answers
Answer:
A. Passive Transport is migration of a molecule from one side of the cell membrane to the other, from an area of high electrochemical potential to a region of lower electrochemical potential.
B. Diffusion is an individual molecule of a material moving from a high-concentration location to a low-concentration area over a semipermeable barrier
C. Osmosis is the movement of molecules of water through a cell's partly permeable membrane from a liquid with a large concentration of water molecules to a solution with a lower concentration of water molecules.
D. Facilitated Diffusion are molecules that diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
E. Active transport is the transport of molecules across a cell membrane against a concentration gradient from a low-concentration region to a high-concentration region.
F. Selectively permeable is when some chemicals or ions pass across the membrane, while others are blocked.
G. Cellular respiration are organisms mix oxygen with food molecules, directing the chemical energy in these substances into life-sustaining processes while eliminating carbon dioxide and water as waste material.

Is diphenylmenthane a solid or liquid at room temperature
Answers
Answer:
diphenylmethane is liquid at room temperature.
Explanation:
It is a solid below room temperature and its melting point is at 22 degree celsius to 24 Celsius degree celsius.
Diphenylmethane is a solid at room temperature. Diphenylmethane is a non-polar compound.
Diphenylmethane is a colorless, crystalline solid with a melting point of 53 °C. It is a member of the diphenylmethanes, which are a class of organic compounds that contain two benzene rings joined by a single carbon-carbon bond.
Diphenylmethane is a non-polar compound, which means that it does not have any permanent dipole moments. This makes it difficult for the molecules of diphenylmethane to interact with each other, which is why it is a solid at room temperature.
If diphenylmethane were a polar compound, the molecules would be able to interact with each other through dipole-dipole interactions. This would make the compound more likely to be a liquid at room temperature.

what kind of state is a roller coasters are the best use of Newton's laws of motion
Answers
I am slightly unsure on the question, but if you are asking what kind of "statement" is "roller coasters are the best use of Newton's laws of motion" then the following should answer your question:
Answer:
An opinion.
Explanation:
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The statement, "Roller coasters are the best use of Newton's laws of motions" is an opinion because it is not based on any evidence, facts, or proof to back it up.
