Theoxidizer that is added to hydrogen peroxide to increase its chemical action is known as the _____.
- A.
Generator
- B.
Penetrator
- C.
Activator
- D.
Accelerator
Correct Answer
C. ActivatorExplanation
Hydrogen peroxide is a powerful oxidizing agent, but its chemical action can be enhanced by adding an activator. An activator is a substance that increases the rate of a chemical reaction without being consumed in the process. In the case of hydrogen peroxide, an activator is added to increase its ability to break down into water and oxygen. This reaction is commonly used in various applications, such as hair bleaching or as a cleaning agent. Therefore, the correct answer is "activator."Rate this question:

The five main elements that make up the chemical compostion of human hair are carbon, oxygen, hydrogen, and:
- A.
Protein and amino
- B.
Cells and keratin
- C.
Elements and protein
- D.
Nitrogen and sulfur
Correct Answer
D. Nitrogen and sulfurExplanation
Human hair is primarily composed of protein, specifically a protein called keratin. Keratin is made up of various amino acids, which contain nitrogen and sulfur. These elements play a crucial role in the structure and strength of the hair. Nitrogen is necessary for the formation of amino acids, which are the building blocks of proteins, while sulfur helps to form disulfide bonds that contribute to the hair's strength and resilience. Therefore, nitrogen and sulfur are essential elements in the chemical composition of human hair.Rate this question:

The natural hair pigment found in the cortex layer of the hair is :
- A.
Melanin
- B.
Tissue
- C.
Protein
- D.
Brown
Correct Answer
A. MelaninExplanation
Melanin is the natural hair pigment found in the cortex layer of the hair. It is responsible for the color of our hair, skin, and eyes. Melanin is produced by specialized cells called melanocytes, which are located in the hair follicles. The amount and type of melanin determine the color of our hair, with higher levels of melanin resulting in darker hair and lower levels resulting in lighter hair. Melanin also provides protection against harmful UV radiation from the sun.Rate this question:

The division of a bacterial cell into two cells is called:
- A.
Spore growth
- B.
Decomposing
- C.
Mitosis
- D.

Correct Answer
C. MitosisExplanation
Mitosis is the correct answer because it is the process by which a bacterial cell divides into two identical daughter cells. During mitosis, the genetic material of the bacterial cell is replicated and then evenly distributed between the two daughter cells. This process allows for growth and reproduction of bacterial populations. Spore growth, decomposing, and fertilizing are not accurate terms to describe the division of a bacterial cell into two cells.Rate this question:

Colors with a predominance of red are considered to be _____ tones.
- A.
Warm
- B.
Cool
- C.
Neutral
- D.
Primary
Correct Answer
A. WarmExplanation

The nail should have between ____%and____% water content.
- A.
50% and 75%
- B.
5% and 10%
- C.
30% and 50%
- D.
10% and 30%
Correct Answer
D. 10% and 30%Explanation
The correct answer is 10% and 30%. Nails should have a water content between 10% and 30% to maintain their strength and prevent them from becoming too brittle or too soft. If the water content is too low, the nails may become dry and prone to cracking. On the other hand, if the water content is too high, the nails may become weak and susceptible to bending or warping. Therefore, maintaining a water content within the range of 10% to 30% is crucial for the optimal performance and durability of nails.Rate this question:

What product is used to open the cuticle of the hair fiber so that tint can penetrate it ?
- A.
Hair conditioner
- B.
Color filler
- C.
Alkalizing agent
- D.

- A.
Developer
- B.
Tint molecules
- C.
Alkalizing ingredient
- D.
Oxidizing agent
Correct Answer
C. Alkalizing ingredientExplanation
An alkalizing ingredient is responsible for raising the cuticle of the hair so that the tint can penetrate. This ingredient helps to open up the hair shaft, allowing the tint molecules to enter and color the hair effectively. By creating a more alkaline environment, the alkalizing ingredient helps to break down the natural barriers of the hair, making it more receptive to the tint. This process ensures that the tint can fully penetrate the hair shaft and provide long-lasting and vibrant color results.Rate this question:

Permanent haircolors contain uncolored dye precursors known as:
- A.
Color fillers
- B.
Developers
- C.
Toners
- D.
Aniline derivatives
Correct Answer
D. Aniline derivativesExplanation
Permanent haircolors contain uncolored dye precursors known as aniline derivatives. Aniline derivatives are compounds that are used in hair dyes to create the desired color. These derivatives react with the developer (usually hydrogen peroxide) to form colored molecules that penetrate the hair shaft and provide long-lasting color. Color fillers are used to fill in gaps in the hair shaft, developers are used to activate the dye, and toners are used to adjust the tone of the color. However, in permanent haircolors, it is the aniline derivatives that are responsible for the actual color formation.Rate this question:
