<h3>What is an electrical impulse?</h3>

An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.

In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.

Therefore, the correct option is A.

Do the light reactions of photosynthesis depend on the calvin cycle?

True [87]

Answer:

The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.

If you observed the sister chromatids separating during cell division, what phase of mitosis would you be observing?

Sidana [21]

This is the anaphase of mitosis. Anaphase is characterized by the separation of sister chromatids or "pulling away" of the sister chromatids from the metaphase plate to the opposite spindle poles. This is also the phase where chromosomes reach its maximum condensation meaning that the process of the reformation of the nucleus will be shorter and easier.
