Explanation:
The solution of the lactic acd and sodium lactate is referred to as a buffer solution.
A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. In this case, the weak acid is the lactic acid and the conjugate base is the sodium lactate.
Buffer solutions are generally known to resist change in pH values.
When a strong base (in this case, NaOH) is added to the buffer, the lactic acid will give up its H+ in order to transform the base (OH-) into water (H2O) and the conjugate base, so we have:
HA + OH- → A- + H2O.
Since the added OH- is consumed by this reaction, the pH will change only slightly.
The NaOH reacts with the weak acid present in the buffer sollution.

Sunlight penetrates the top layers of the ocean, so photosynthesis occurs there.

i actualky dont know im sorry but when i figure out i will give it to you
Dalton theory is based on atomic theory and now is known as formula weight whereas Gay-Lussac measured the volume of the gases.
Now, Dalton verified the law of multiple proportions theory but he was not able to state the change in volume from 4 to 2 in case of nitrogen and hydrogen (at constant temperature and pressure) whereas Gay-Lussac verified the results and prepared gases theory by combining volumes of gases.
