Chlorine is added in the water treatment process because it kills off all of the bacteria and bad things inside of the water that may not be seen. It doesn’t necessarily “filter” it out, it’s just because the organisms living inside of it die because of the chemical element.

When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!

What are 3 nonpolar molecules used in everyday life?
Tresset [83]
Three nonpolar molecules that are used in everyday live are carbon dioxide (CO2), methane (CH4), and ethylene (C2H4).

Ethylene is used to make plastic and ripen fruits and methane is used to produce electricity and power garbage trucks. Besides its usage in the crucial processes of photosynthesis and cell respiration that keep us alive, carbon dioxide is important in refrigeration and is also found in fire extinguishers.

Hope this helps!

A child is prescribed hematopoietic stem cell transplantation for severe combined immunodeficiency disease. what is administered
mezya [45]
The child is administered to use Intravenous immunoglobulin and Pneumocystis caranii pneumonia or PCP prophylaxis. These are used to improve humoral immunity in the child until the time when the transplant is performed.
The child is not recommended to use influenza vaccine in immunodeficiency disease reason being the possibility of acquiring influenza which is severe.
Again the child is not recommended to use varicella vaccine because it can lead to a risk of acquiring chicken pox.
For a child with PCP, we use Dapsone.
