Answer:

See the answer below

Explanation:

From the graph, the concentration of salt solution where the number of burst red blood cells equals the number of intact ones is 0.40 g/100 cm3<u>.</u>

<em>At this concentration, the percentage of burst cells is 50, meaning that the remaining 50% of the cells in the experiment remained intact.</em>

The totality of the concentrations of all the salt solutions used is:

0.30+0.35+0.40+0.45+0.50 = 2 g/100 cm3

Thus, the percentage of salt solution concentration when the number of red blood cells that burst is the same as the number of red blood cells that do not burst equals;

          0.40/2 x 100% = 20%

The products of the light reactions of photosynthesis are ______.
Pachacha [2.7K]

The correct answer is - B) ATP and NADPH.

The products of the light reactions of the process of photosynthesis are the ATP and NADPH. The small amount of ATP produced in this process and the energy carrier NADHP are crucial for the functioning of the organisms that use the process of photosynthesis, and the reason for that is that these two are used by the organisms to create glucose, or rather sugars, in the process called the Calvin Cycle. The glucose is what these organisms use as their food, a food they they manage to make themselves, thus making them producers. If the light is missing, then the process of photosynthesis can not be performed because the formation of ATP's will be stopped, as well as the formation of NADHP, so the organisms will not be able to produce their own food.

ollegr [7]

Answer:

the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance

Explanation:

It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant. Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed
