Answer:

Option C, operate the automatic safety controls

Explanation:

A heat system must be inspected for the following automatic safety features -

A) automatic fire-extinguishing system - a system  that automatically detects a fire and discharges something to stop it

B) Automatic sprinkler system - A sprinkler system for fire-protection purposes

c) humidistat - to automatically control relative humidity

d) Automatic panel board

e) thermostat to  automatically  maintain temperature

f) an automatic water pump  for removal of waste water

Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. while for many this disorder
kap26 [50]

Answer:

low level of calcium would result in fewer signals sent between pre and post synaptic cells.

Explanation:

The calcium has a main role in signal transmission mechanism and here is the mechanism :

1-the impulse reaches the synapse (depolarization which is a voltage change).

2-the voltage gated calcium channels open and let calcium flow into the cell.

3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)

so it's obvious that if calcium concentration decreases, the signal transmission also decreases.

Alexeev081 [22]

Based on their function, you would expect melanocytes in the skin to have a higher than usual number of ribosomes.

Ribosomes are cell structures that functions as the site of biological protein synthesis. Ribosomes are present in all living cells where they produce proteins required for many cellular functions. Ribosomes join amino acids together in the order specified by messenger RNA molecules. Ribosomes are made up of two parts which are; the large subunits (which connect amino acids to create a polypeptide chain) and the small ribosomal subunits (which read the RNA).
