When the temperature of the human body falls to a level that is potentially fatal, the body's natural reaction is to keep the heart pumping. This means that circulation to other organs besides the heart is stopped. This is why limbs get frostbite in extreme cold.

Diffusion is essential for both animal and plant cells as it facilitates the movement of essential substances, such as oxygen, carbon dioxide, and nutrients, across cell membranes. This process helps maintain cellular homeostasis by allowing cells to acquire necessary materials and expel waste products. In plants, diffusion is crucial for gas exchange in leaves, while in animal cells, it supports vital metabolic functions. Overall, diffusion ensures that cells can efficiently obtain and regulate their internal environments.
Yes, large cells and small cells both carry out diffusion and osmosis, but the rates can differ. Smaller cells generally have a higher surface area-to-volume ratio, allowing for more efficient and faster diffusion and osmosis compared to larger cells. As cells increase in size, the volume grows faster than the surface area, which can slow down these processes. Therefore, smaller cells typically exchange materials more rapidly than larger cells.
Moat materials, or protective substances used in various applications, can enter cells through several mechanisms, primarily involving endocytosis and passive diffusion. Endocytosis allows cells to engulf materials by wrapping them in a portion of their membrane, forming a vesicle that transports the materials inside. Alternatively, some small, non-polar molecules can pass directly through the lipid bilayer of the cell membrane via passive diffusion. Additionally, specific transport proteins can facilitate the uptake of particular substances.
Diffusion and Convection. In molecular diffusion, the moving entities are small molecules. Diffusion is the thermal motion molecules at heated temperature. Diffusion rate is a function of only temperature, and is not affected by concentration. I do believe this answer is most likely wrong.
Temperature can influence the diffusion of materials in cells by affecting the kinetic energy of molecules. Higher temperatures increase the speed and energy of molecules, leading to faster diffusion rates. Conversely, lower temperatures decrease diffusion rates as molecules have less energy to move across cell membranes. Optimal temperatures promote efficient diffusion within cells.

Blood moves materials past cells, allowing for diffusion. It also moves cells themselves to places they are needed, as with immune system cells.
Diffusion is one of the processes of transferring materials within the cells of living organisms. An example of diffusion is the exchange of gases in the lungs.

Some ways in which material may move in and out of cells are diffusion and also osmosis.
