Answer:

K2S

Explanation:

Potassium has a ionic charge of +1 and sulfur has a ionic charge of -2. Swap charges so that Potassium has -2 and sulfur has +1. Drop the charges. It'll be K2 and S1. When doing the crisscross method, you drop the one. Therefore, it is K2S.

The output region is the site of ______________________.
tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.

What percentage of water is lost through the respiratory system?
HACTEHA [7]
<span>The normal daily input of water is about 2.5 L from beverages food, and metabolism. The normal daily output of 2.5 L consists of 1.8 L in urine, sweat, and feces, plus 0.7 L in insensible water loss. Insensible water loss is water that evaporates through the skin and from the respiratory tract. Insensible losses account for 0.7 L of water loss per day. The average human exhales an average of 0.35 L of water each day. This corresponds to about 14% of water lost through respiration.</span>
