Answer:A, C
Explanation:
Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
Answer: More water will be transferred from the nephron
The excretory system is the system in the organisms body which allows the excretion of unwanted waste metabolites from the body like nitrogenous wastes like ammonia, salts and excess of water. Water is the chief ingredient of blood it decreases the viscosity of blood and prevents it's clotting.
In the case of hypertension or high blood pressure the excretory system plays an important role by expelling more amount of water out of the body. Therefore, more amount of water will be transferred from the nephron to the urinary bladder. It is an internal control of the body. It increases the urge to urinate to expel the water and preventing the ill effects of high blood pressure.
Answer:
<u>In the mitochondrial matrix</u>
<u></u>
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into 
(carbon dioxide) and 
(water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
