The two point discrimination test
is used to determine sensitivity to touch. This test is performed to evaluate the
ability of an individual to identify two close points on a small area of skin
and how well the individual can discriminate the points. The test can be done by
using calipers.

4.Answer: There are more molecules in a gram of water.
Explanation: Specific heat is the heat required by 1 gram of a substance to raise its temperature by .
As the specific heat of water (4.186 J/g°C) is more than that of ethanol (2.450 J/g°C) it means more energy is required to raise the temperature of a gram of water by 1°C. Which means the molecules are tightly bound and thus more molecules are contained in a gram of water.
Q= heat gained
m= mass of the substance
c = heat capacity

Explanation:
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.
To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.
In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.
- In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content. According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
- In basic solutions, the concentration of OH- ions is higher than that of H3O + ions. If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution. Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
