Answer:

Explanation:

First of all, we need to understand what gravity is. Gravity in its simplest form can be best visualized as a force of attraction, that pulls all objects that have a mass towards itself.

It is usually exerted by an object with a larger mass and felt by objects with smaller masses.

Putting this into context, the earth exerts a gravitational pull on all substances with masses, which are around it. This includes the oceans, birds, airplanes, clouds, and even gasses in the atmosphere. The atmospheric gasses may be light enough to float, but they can't go very far, since gravity is constantly tugging at them. This keeps the gasses that make up our atmosphere, within a reasonable radius, which is very close to the earth. In a nutshell, gravity prevents them from floating away into outer space.

The following equation shows the equilibrium in an aqueous solution of ammonia: NH3(aq)+H2O(l)⇌NH4+(aq)+OH−(aq)NH3(aq)+H2O(l)⇌NH

yarga [219]

Answer:

c) H2O and OH−

Explanation:

Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.

When an acid donates a proton, it changes into a base which is known as its conjugate base.

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.

Thus, for the reaction,

$NH_3+H_2O\rightleftharpoons Nh_4^++OH^-$

The base is $NH_3$ and the conjugate acid of the base is $NH_4^+$ .

Also, The base is $OH^-$ and the conjugate acid of the base is $H_2O$ .

Correct option is :- c) H2O and OH−

The reactions of glycolysis occur in the cell's ________; the reactions of the citric acid cycle occur in the ________.

Reil [10]

Answer:

The reactions of glycolysis occur in the cell's cytoplasm; the reactions of the citric acid cycle occur in the mitochondria.

Explanation:

Explanations of some terms

Glycolysis

Glycolysis takes place in the cytosol of the cell's cytoplasm. Glycolysis starts when glucose diffuses into a cell through the plasma membrane down its concentration gradient. Glycolysis is a metabolic pathway present in all organisms: from yeast to mammals that involves the oxidation of glucose molecules, the single most important organic fuel in plants, and animals to pyruvate with the generation of ATP (Adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide + hydrogen)

Citric acid cycle

Citric acid cycle also known as the Krebs cycle plays a major role in the process of energy production and biosynthesis as it oxidizes glucose derivatives, fatty acids and amino acids to carbon dioxide.
