Questions and Answers

1.

Contain H and O in a 2:1 ratio.
- A.
  
  Carbohydrates
- B.
  
  Lipids
- C.
  
  Proteins
- D.
  
  Nucleic acids
- E.
  
  None
Correct Answer
A. Carbohydrates

Explanation
Carbohydrates are organic compounds that consist of carbon, hydrogen, and oxygen in a 2:1 ratio, with the general formula (CH2O)n. This means that for every one carbon atom, there are two hydrogen atoms and one oxygen atom. This ratio is essential for the formation of carbohydrates, which include sugars, starches, and cellulose. Lipids, proteins, and nucleic acids do not have this specific ratio of H and O atoms, making carbohydrates the correct answer.

Monomers do not contain N.
- A.
  
  Carbohydrates
- B.
  
  Lipids
- C.
  
  Proteins
- D.
  
  Nucleic acids
- E.
  
  None
Correct Answer(s)
A. Carbohydrates
B. Lipids

Explanation
Carbohydrates and lipids are organic compounds that are composed of carbon, hydrogen, and oxygen atoms. They do not contain nitrogen (N) in their chemical structure. On the other hand, proteins and nucleic acids are biomolecules that do contain nitrogen atoms. Therefore, the correct answer is carbohydrates and lipids, as they are the only options that do not contain nitrogen.

C12H22O11
- A.
  
  Carbohydrates
- B.
  
  Lipids
- C.
  
  Proteins
- D.
  
  Nucleic acids
Correct Answer
A. Carbohydrates

Explanation
The given chemical formula C12H22O11 represents a carbohydrate known as sucrose, which is a common type of sugar found in plants. Carbohydrates are organic compounds that serve as a major source of energy for living organisms. They are composed of carbon, hydrogen, and oxygen atoms in a specific ratio. Lipids, proteins, and nucleic acids are other types of biomolecules, but the given chemical formula does not correspond to any of them. Therefore, the correct answer is carbohydrates.

Fats, oils, and waxes.
- A.
  
  Carbohydrates
- B.
  
  Lipids
- C.
  
  Proteins
- D.
  
  Nucleic acids
- E.
  
  None
Correct Answer
B. Lipids

Explanation
Lipids are a class of organic compounds that include fats, oils, and waxes. They are characterized by their insolubility in water and solubility in organic solvents. Lipids are an essential component of living organisms and serve various functions such as energy storage, insulation, and protection. Therefore, lipids are the correct answer in this case.

Monomers made of sugar, N-base, and phosphate.
- A.
  
  Carbohydrates
- B.
  
  Lipids
- C.
  
  Proteins
- D.
  
  Nucleic acid
- E.
  
  None
Correct Answer
D. Nucleic acid

Explanation
Nucleic acids are polymers made up of monomers that consist of a sugar, a nitrogenous base, and a phosphate group. This description matches the given answer "monomers made of sugar, N-base, and phosphate." Carbohydrates are not composed of these specific components, lipids do not contain nucleic acids, and while proteins are made up of amino acids, they do not include the specific components mentioned. Therefore, the correct answer is nucleic acid.

6.

What is this?
- A.
  
  Protein polymer
- B.
  
  Protein monomer
- C.
  
  Carbohydrate polymer
- D.
  
  Carbohydrate monomer
Correct Answer
D. Carbohydrate monomer

Explanation
A carbohydrate monomer refers to a single unit or molecule of a carbohydrate. Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms. They serve as a major source of energy for living organisms. Monosaccharides, such as glucose and fructose, are examples of carbohydrate monomers. They can combine through dehydration synthesis to form larger carbohydrate polymers, such as disaccharides (e.g., sucrose) and polysaccharides (e.g., starch and cellulose). Therefore, the correct answer is carbohydrate monomer.

7.

What is this?
- A.
  
  Protein polymer
- B.
  
  Carbohydrate polymer
- C.
  
  Nucleic acid polymer
- D.
  
  Lipid polymer
Correct Answer
C. Nucleic acid polymer

Explanation
This question is asking for the identification of the given substance. The answer, "nucleic acid polymer," suggests that the substance is a type of polymer made up of nucleic acids. Nucleic acids are the building blocks of DNA and RNA, which are vital for genetic information storage and protein synthesis. Therefore, the correct answer implies that the substance in question is a polymer made up of nucleic acids, such as DNA or RNA.

  Lipid polymer
Correct Answer
D. Lipid polymer

Explanation
Lipids are a class of biomolecules that are insoluble in water but soluble in organic solvents. They are composed of fatty acids and glycerol and serve as a major structural component of cell membranes. Lipids can form polymers through the process of polymerization, joining together multiple lipid molecules to create larger structures. Therefore, the correct answer is lipid polymer.

  Lipid polymer
Correct Answer
A. Protein polymer

Explanation
Protein polymer is the correct answer because proteins are composed of long chains of amino acids, which are linked together through peptide bonds to form a polymer. Proteins play various essential roles in the body, including providing structure, facilitating chemical reactions, and serving as messengers.
