The growth of plant seedlings is usually

Biology
1 answer:
zhenek [66]2 years ago
7 0

Answer:

The correct answer is - A. phototropic and gravitropic.

Explanation:

A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.

The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

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.

Is infant circumcision ethically necessary?
Nostrana [21]
The answer is that infant circumcision is not ethically necessary. The reason to this is that there are no proof of evidence as to why it is ethically necessary for it to be done to an infant. It is also because other medical professionals thinks that doing circumcision in an infant will create issues in terms of their health, producing complications. That is why it is not ethically necessary for it to be done on an infant.
