Answer:c. Separated DNA is attached to the cell membrane before the cell divides.
Explanation:
The prokaryotes are single celled organisms. These are simple organisms which reproduce through asexual mode of reproduction that is cell division. They do not posses well define nucleus. Thus the genetic material remain in the cytoplasm of the cell. On cell division the genetic material (DNA) is distributed into halves for development of two daughter cells. Due to lack of nucleus and it's associated membrane the separated DNA get attach to the membrane before the cell actually divides.
Answer:
d)Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered
Explanation:
Acetylcholinesterase also referred to as AChE, is an enzyme that catalyzes the breakdown of acetylcholine and some other choline esters in the body and this is achieved by breaking down the acetylcholine into its two component parts, acetic acid and choline.
A careful look at the chemical structure of acetylcholine and epinephrine shows differences in the chemical group present and therefore acetylcholinesterase cannot catalyze the break down of epinephrine.
This family trait that skips a generation comes from an autosomal recessive trait or as Mendel called as hidden non-dominant trait. Offsprings have a dominant and recessive trait which comes from both parents. Recessive trait appears only when two offspring with same recessive trait blends. This happens in self-fertilization. In the human population, marriage is prohibited between offsprings, thus having recessive trait is only imminent when cousins are married.
Each organelle has it's own specific function to help the cell survive. The
nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
Eukaryotes also have a golgi apparatus that packages and distributes
proteins. Mitochondria are the power house of the cell and provide the cell
with energy
The answer is d. b and c.
Bacteria are simple organisms with great biotic potential and the greatest metabolic diversity on Earth.
