A neuron has a cell body (soma), dendrites(inputs), and an axon (the output).

Neurons can send signals to one another across small gaps between them called synapses; if enough signals are received and go down the dendrites and reach a trigger point on the soma, a spike, or impulse, called an action potential will fire along the axon to its end, which will cause neurotransmitters to be released into a synapse, sending the signal onward.

Can you Briefly describe the physiological process of nutrition respiration and excretion in a sponge?

As water passes through the sponge particles are trapped and engulfed by choanocytes that line the body cavity. as water moves through the sponges, oxygen is diffused into the cells and carbon dioxide and other wastes such as ammonia is diffused out of the cells see explanation for solution.


Name and briefly describe three functions of proteins?

Proteins are an essential part of living organisms. Their functions include controlling growth, serving as enzymes to catalyze chemical reactions in the body, and as transport and storage molecules.


Briefly describe how a biological contaminant was able to get into groundwater wells at walkerton?

The biological contaminant, E. coli bacteria, likely entered the groundwater wells at Walkerton due to surface water runoff carrying manure from nearby farms contaminated with the bacteria. Heavy rainfall washed the E. coli from the manure into the groundwater supply, leading to widespread contamination.


Briefly describe what happens during prophase?

During prophase, the nuclear membrane breaks down, the chromatin condenses into chromosomes, and the centrioles move to opposite poles of the cell. This prepares the cell for cell division and the separation of genetic material.
