Answer:

The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Explanation:

In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  

These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.

Which choice ranks the elements hydrogen, carbon, nitrogen, and oxygen in order of decreasing dry mass in human cells a. O→C→H→N
True [87]

<u>Answer:</u> The order of decreasing dry mass in human cells is C→O→H→N

<u>Explanation:</u>

Dry mass of the element in human cells means the mass of elements which have lost all the water.

Human cells consist of many chemical elements. Some of them are: Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), calcium (Ca), sulfur (S), potassium (K), sodium (Na), chlorine (Cl), magnesium (Mg) and many more.

Most abundant element found in the human cells is carbon.

The composition of the dry mass of the elements in human cells are:

Carbon = 47 %

Oxygen = 30 %

Hydrogen = 9 %

Nitrogen = 8 %

Phosphorus = 3 %

Sulfur + Potassium + Calcium + Sodium + Chlorine + Magnesium = 2 %

Other elements = 1 %

The decreasing order of dry mass of elements in human cells is:

C>O>N>H

Hence, the order of decreasing dry mass in human cells is C→O→H→N

According to friedrich, when food and fluid intake is poor, starvation occurs before dehydration
Solnce55 [7]

The statement of Liz Friedrich is verified by evidence from research of a physiologic adaptation, during the vanishing development, the famine that averts any uneasiness as a outcome of the absence of food. Dehydration may result to hemoconcentration and hyperosmolality, with consequent azotemia, hypernatremia, and hypercalcemia. These metabolic fluctuations may create a soothing effect on the brain before passing away.
