One example of passive transport is diffusion, when molecules move from an area of high concentration (large amount) to an area of low concentration (low amount). Molecules are said to naturally flow down their concentration gradient
it involved in the transfer of genetic material from one cell to another.
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
For one thing based off of process of elimination we know that both plant and animal cells have a cell membrane, and a nucleus. Therefore we are left with cytoplasm and cell wall. According to the question we are most likely looking for something in the animal or plant cell that they don’t have in common with each other. Therefore, the answer is cell wall because an animal cell doesn’t have a cell wall, but a plant cell does. The cell wall can also make it more rigid!
