In this question, you are asked to make 5% Calcium chloride(CaCl2) solution. For every 1000ml of water, the weight should be 1000grams. Then for 5% solution, the CaCl2 needed would be:
5% * 500 ml * 1gram/ml= 25grams
Calcium chloride is made from 1 calcium and 2 chlorine, so the molecular mass would be (1*40) + (2*35.5)= 111 gram/moles. Then, 25 grams of CaCl2 would be: 25gram / (111 gram/moles)= 25/111 moles.
Molarity unit is mole per 1000ml of solvent. So the molarity of the solution would be: (25/111 moles) / (500ml/1000ml)= 50/111M= 0.45M
The effect of the neurotransmitters tends to be fast, as in a case of external stimuli, which leads to a quick reaction of the body, towards that stimulus.
The effect of a hormone, however, is long-lasting, where hormones actually are working on the metabolic or structural situations, which are going to have a long-lasting effect on the body.

The strength of the gravitational force between two objects depends on two factors mass and distance. The force of gravity the masses exert each other increases the force of gravity decreases.
If the distance is doubled the force of gravity is one fourth as strong as before.

Explanation:
1) Olfactory nerves are responsible for our sense of smell while auditory nerves are responsible for our sense of hearing.
2) Olfactory nerves are the shortest nerves and are those that enter the skill through the cribform plate from the ethmoid zone while auditory nerves is one out of two parts of the vestibulocochleer which is described as a cranial nerve that's present in amniotes. The other part is the vestibular nerve.
