What statement correctly compares the pH of water to that of other substances

1 answer:

7 0

Ph of water is typically a Ph of 7 AKA...or neutral.

The Ph scale goes from 14 being base to extremely acidic 0.
Typically a Ph lower than 7 is considered acidic.
7 is the neutral zone.

Water depending from where you get the liquid can range between
6.5 ph to 8.5.
Usually 7 neutral!

Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glu

Tanzania [10]

Answer:

(B) Interstitial fluid

Explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.

What stage of respiration immediately follows the process depicted below? Two pyruvate molecules undergo a chemical reaction, co

Nadya [2.5K]

Answer:

Electron transport chain

Explanation:

Cellular respiration is the process whereby glucose is broken down in the cell to yield energy in form of ATP. This process, which is important to the metabolic functioning of every organism, occurs in three major stages namely: glycolysis, kreb's cycle and electron transport chain (ETC).

According to this question, a stage of respiration is described as follows:

- Two pyruvate molecules undergo a chemical reaction, combining with coenzyme A to form two acetyl-CoA molecules.

- Two carbon dioxide molecules and two NADH molecules are formed as a result of this process.

The process depicted above is KREB'S CYCLE of cellular respiration, hence, the stage of respiration that immediately follows the process is called ELECTRON TRANSPORT CHAIN (ETC).
