The right answer is 2HgO → 2Hg + O2

Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.

In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.

A chloroplast has stopped producing atp and NADPH
ElenaW [278]

The question is incomplete, so the complete question is as follows:

A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?

a.The chloroplast has used up its supply of chlorophyll molecules.

b.Electrons have stopped moving through the electron transport chain.

c.The sun has risen and the chloroplast now can make more chlorophyll.

Answer:

b.Electrons have stopped moving through the electron transport chain.

Explanation:

ATP and NADPH are produced in the light dependent reaction stage of the photosynthesis that occurs within chloroplast grana.

ATP and NADPH are produced due to the movement of electron and proton (H+) in the electron transport chain, so if the movement of electrons will stopped in the electron transport chain, the formation of ATP and NADPH will also get stop.

Hence, the correct answer is "b".

Describe one way osmosis and osmotic pressure is important to medicine.
OleMash [197]

Answer:

Since the beginning of life of the first multicellular organisms, the preservation of a physiologic milieu for every cell in the organism has been a critical requirement. A particular range of osmolality of the body fluids is essential for the maintenance of cell volume. In humans the stability of electrolyte concentrations and their resulting osmolality in the body fluids is the consequence of complex interactions between cell membrane functions, hormonal control, thirst, and controlled kidney excretion of fluid and solutes. Knowledge of these mechanisms, of the biochemical principles of osmolality, and of the relevant situations occurring in disease is of importance to every physician. This comprehensive review summarizes the major facts on osmolality, its relation to electrolytes and other solutes, and its relevance in physiology and in disease states with a focus on dialysis-related considerations.
