The ATP molecule splits off one of its three phosphates when a cell has to expend energy to complete a task, resulting in the formation of ADP (Adenosine di-phosphate) + phosphate.

That phosphate molecule's energy is no longer bound to it and can now be used by the cell to perform tasks. Energy is released and ATP is changed into adenosine diphosphate when one phosphate group is removed by breaking a phosphoanhydride bond during a procedure known as hydrolysis (ADP).

As with the removal of a phosphate from ADP to create adenosine monophosphate, energy is likewise released (AMP). Adenosine diphosphate (ADP) is a chemical that transfers and supplies energy to cells. The primary energy molecule that cells need to power their processes is adenosine triphosphate (ATP). The phosphate bonds between them contain energy.

The most likely causes of genetic variation are random mating, genetic mutation and genetic drift.

The changes which occur in the genetic sequence of the DNA of an individual are known as genetic variations. They play a very important role in the bringing about evolution and increasing the survival rate of organisms.

The most likely causes of genetic variation are random mating, genetic mutation and genetic drift. Genetic drift is a shift in the allelic frequency of a population which occurs due to a random chance. Random mating is the mating between two individuals which is not dictated by any social or genetic preference and genetic mutations are the change in the sequence of the DNA which might occur due to exposure to UV rays, chemicals or some errors in replication.

We will prove that the subset (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C) is included in (A ∪ B) - (B ∩ C) using an element argument.

Let x be an arbitrary element in (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C). This means that x belongs to either (A' ∩ B ∩ C) or (A ∩ B ∩ C). We will consider both cases separately.

Case 1: x belongs to (A' ∩ B ∩ C)

If x is in (A' ∩ B ∩ C), it satisfies three conditions: it is not in A, it is in B, and it is in C. Since it is not in A, x must be in B. Moreover, since it is in B and in C, it satisfies the condition (x ∈ B) ∧ (x ∈ C), which means it is in (B ∩ C). Therefore, x satisfies the conditions to be in (A ∪ B) - (B ∩ C).

Case 2: x belongs to (A ∩ B ∩ C)

If x is in (A ∩ B ∩ C), it satisfies three conditions: it is in A, it is in B, and it is in C. Since it is in A and in B, it satisfies the condition (x ∈ A) ∧ (x ∈ B), which means it is in (A ∪ B). However, since it is in B and in C, it also satisfies the condition (x ∈ B) ∧ (x ∈ C), which means it is not in (B ∩ C). Therefore, x also satisfies the conditions to be in (A ∪ B) - (B ∩ C).

In both cases, we have shown that x satisfies the conditions to be in (A ∪ B) - (B ∩ C). Since x was arbitrary, we can conclude that every element in (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C) is also in (A ∪ B) - (B ∩ C), proving the subset inclusion.

The vocabulary word that describes the phenomenon of water molecules sticking to the molecules of other substances is "adhesion."

Adhesion refers to the attraction or sticking together of different molecules or substances. In the case of water, it has a unique ability to form hydrogen bonds,, which allows it to adhere to various surfaces or molecules.

When water comes into contact with another substance, such as the surface of a solid or a solute dissolved in water, the water molecules can adhere to the molecules of that substance. This adhesion occurs due to intermolecular forces, specifically hydrogen bonding.

Adhesion is responsible for various phenomena, such as capillary action, where water can rise in narrow tubes against the force of gravity, and the ability of water to wet or spread across surfaces. It also plays a role in biological systems, where adhesion allows water to stick to cell surfaces or move through plant tissues.

In summary, adhesion is the term used to describe the sticking or attraction of water molecules to the molecules of other substances due to intermolecular forces, particularly hydrogen bonding.

The major organic product the Friedel-Crafts acylation reaction is attached in the image below.

The Friedel-Crafts acylation reaction is a commonly used organic reaction that involves the introduction of an acyl group (RCO⁻) onto an aromatic compound. The reaction is catalyzed by a Lewis acid, typically aluminum chloride (AlCl₃), and requires the use of an acid chloride or anhydride as the acylating agent.

The reaction proceeds through the formation of a complex between the Lewis acid and the acylating agent, which activates the electrophilic carbon of the acyl group. This electrophile is then attacked by the nucleophilic aromatic ring, resulting in the formation of a new carbon-carbon bond. The reaction can be used to synthesize a variety of aromatic ketones and other acylated products and has important applications in the production of pharmaceuticals, fragrances, and other fine chemicals.
