Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears
Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
