Answer:
A. simple
Explanation:
Asexual reproduction is mainly used by bacteria or small organisms that are too simple to have created a mechanism for sexual reproduction. The advantage of sexual reproduction is the recombination--why do you think you're not an exact copy of your parent? That's because they didn't have you via asexual reproduction.
Why not B: This is the opposite.
Why not C: This isn't necessarily a requisite condition; many bacteria do not live underwater.
Why not D: This is certainly wrong. Bacteria are not extinct, and not looking to be so anytime soon.
It is polymerase chain reaction hope this helps
Think of it as a zipper. The top zipper is the leading strand, the bottom is the lagging, and the actual zipper thing is the helicase unwinding the 2 parts. You need the top and bottom strands to have a replication fork
Answer:
Hyperpolarization
Explanation:
When the membrane potential becomes more negative than the resting potential, the membrane is hyperpolarized. Hyperpolarization is inhibitory in nature and decreases the ability of the neuron to generate a neural impulse. During signal transmission at a chemical synapse, binding of neurotransmitters to the receptors stimulates the opening of ligand-gated ion channels. The flow of ions changes the voltage across the membrane and may cause depolarization or hyperpolarization. For instance, the opening of Cl– or K+ channels causes hyperpolarization.
