How can you tell a vein from other structures in the leaf?

Biology
1 answer:
nevsk [136]3 years ago

You can tell the vein from the others by holding the leaf up to a light. This makes the leaf a bit see through and the veins will be clearly visible as they do not become semi-transperent. You can also put paper on top of the leaf and rub gently over the paper with crayon to see the veins. They will make darker or lighter lines on the paper depending on if you have the leaf facing up or down.

When a neuron is activated by a stimulus, its plasma membrane will change until it reaches a membrane potential of about 40 mV.
grandymaker [24]

Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.

Explanation:

The charge in plasma membrane occurs with diffusion and electric fields.

For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).

The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.

For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.

The like charges repel, and opposite charges attract.
