B has smaller cells but more surface area than A.
there are no slow moving photons, they move at speed of light.
volume increases faster than its surface area
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.

Because if they did not separate nutrients and waste could not move acroos the cell membrane quickly enough to send it throughout the entire cell. This would cause the cells to die. That is why they divide instead of growing larger.
Down the phloem
It has a larger ratio of surface area to volume A.S.Apex :)
The cell has more trouble moving enough nutrients & wastes across the cell membrane.
moving nutrients into the soil, it s a decomposer.
The heart is the prime motivation for moving blood round the body, with a section for oygenating it through the lungs, and a section for supplying nutrients to body parts.
I believe it was the cycle of biosphere nutrients, you may ask how I got this answer I really don't know and don't care, why because I said so bub.

In Delaware, the legal age of majority is 18. If you move out of your parents' house before turning 18 without their permission, they could report you as a runaway, and you may face consequences such as being returned home by law enforcement. It's best to discuss your situation with your parents and seek a resolution that ensures your safety and well-being.
