Which best explains the relationship between structure and function of the cell membrane ? a- the single layer membrane surrounding the outside of the cell allows for the east removal of waste. b- the lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell c- the fluids inside the membrane buffers the chemical reaction taking place inside the cell d- the lipids from the membrane provide energy for protein synthesis

Cells tend to have a relatively small and uniform size. why aren’t cells larger?

The endoplasmic reticulum (er) is an organelle in some cells. in these cells, it is continuous with the nuclear membrane and forms a large part of the cell\'s total membrane. sort the phrases below as describing rough er, smooth er, both, or neither. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.1) found in prokaryites and uekaryotys2) involved in protein synthesis3) involve in lipid synthesis4) contains molecular chaperones in lumen5) bound with ribosomes6) involved in toxin or drug metabolism7) large systemot internnected tubules,vesicles, and sacs8) "packages" enzymes in vesicles for secretion.

Immature bone cells, or osteoblasts, manufacture a protein called osteoid as well as several hormones. because of this, we would expect osteoblasts to contain numerous a) nuclei. b) ribosomes. c) lysosomes. d) golgi bodies.
