Hyperpolarization means that the ________. Group of answer choices membrane potential becomes more negative than the resting pot
gladu [14]

Answer:

Hyperpolarization means that the membrane potential becomes more negative than the resting potential.

Explanation:

The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.

When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.

Assume sexual reproduction occurs. What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes
Rudik [331]
<span>If the parent's reproductive cells or gametes contain 12 chromosomes each, the number of chromosomes in the zygote is 24. Fertilization is the fusion of two haploid gametes and results in the creation of a diploid zygote. If two haploid gametes containing 12 chromosomes each fuse, the zygote will have 24 chromosomes (12 + 12 = 24).</span>

under what circumtances would it be advantageous to a species to have new combinations of genetic traits
elena-14-01-66 [18.8K]

Answer:

Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection

A glucose molecule could be used as an example of potential energy, why is this true?
OlgaM077 [116]
The answer I believe is A EDIT: I changed my answer sorry for any confusion. It is A  because glucose is also stored away to be used as energy later on when needed.
