3 cups of sperm, and 4 cups of water in order to make the ratio 1:3.
Answer:
The presence of cholesterol in the plasma membranes of some animal cells <u>enables the membranes to stay fluid when cell temperature drops</u>.
Explanation:
Cholesterol is an essential lipid in the basic structure of cell membranes. The membranes must have a fluid structure so that the proteins integrated in them can move ''horizontally'' to interact with their ligands and with other proteins. With excess saturated fat the membranes become rigid, but only with the necessary unsaturated fat the membranes are extremely fluid, and very sensitive to changes in temperature. Cholesterol stabilizes the structure of the membranes; preventing the collapse and crystallization between lipid chains that would lead to loss of fluidity and excessive rigidity in the membrane. By decreasing the temperature; as temperatures drop, fluidity decreases, an effect that partially counteracts the presence of cholesterol.
The DNA in the nucleus and mitochondria are the same.
This is not exactly true, although they are similar. This is not a correct option.
The following three are correct options:
Mitochondria and chloroplasts grow independently from the cell.
This is true, and supports the idea that they previously existed as their own organisms.
Prokaryotic cells, mitochondria, and chloroplasts are all the same size.
All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.
Mitochondria and chloroplasts contain their own ribosomes.This is true as well.
