C. prokaryotes do not have a well defined nuckeus
Answer:
B
Explanation:
Cooling reduces the excitement of the molecules of the DNA hence allowing the hydrogen bonds between the base pairs of the two strands to form hence the DNA is considered to anneal. Heating disrupts the hydrogen bonds and causes the two strands to dissociate.
Answer:
regulates which materials enter and leave the cell
Answer:
The answer is B a net 2 ATPs are always generated per glucose regardless of its source
Explanation
Glycogen breaks down in the muscle so as to have enough glucose for muscle contraction and it produces 2ATPs
Glycogen also breaks down in the liver to release enough glucose which gets to the blood stream and is then taken up by other cells. It also produces 2ATPs at the expense of 6ATPs
Answer:
C. primary cell wall → plasma membrane → cytoplasm → vacuole.
Explanation:
Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.
