Which of the following is not a component of a cell membrane?

  1. Phospholipids

  2. Proteins

  3. Carbohydrates

  4. Nucleic acids


Correct Option: D
Explanation:

Nucleic acids are not a component of the cell membrane. The cell membrane is composed of phospholipids, proteins, and carbohydrates.

What is the function of the Golgi apparatus?

  1. Protein synthesis

  2. Lipid synthesis

  3. Carbohydrate synthesis

  4. Packaging and secretion of proteins


Correct Option: D
Explanation:

The Golgi apparatus is responsible for packaging and secreting proteins. It modifies proteins and lipids, and packages them into vesicles for transport to other parts of the cell or for secretion.

Which of the following is not a type of RNA?

  1. Messenger RNA (mRNA)

  2. Transfer RNA (tRNA)

  3. Ribosomal RNA (rRNA)

  4. Small nuclear RNA (snRNA)


Correct Option: D
Explanation:

Small nuclear RNA (snRNA) is not a type of RNA. The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

What is the function of the mitochondria?

  1. Cellular respiration

  2. Photosynthesis

  3. Protein synthesis

  4. Lipid synthesis


Correct Option: A
Explanation:

The mitochondria are responsible for cellular respiration, which is the process by which cells generate energy from glucose.

Which of the following is not a type of cell division?

  1. Mitosis

  2. Meiosis

  3. Binary fission

  4. Budding


Correct Option: D
Explanation:

Budding is not a type of cell division. Mitosis, meiosis, and binary fission are the three main types of cell division.

What is the function of the chloroplast?

  1. Cellular respiration

  2. Photosynthesis

  3. Protein synthesis

  4. Lipid synthesis


Correct Option: B
Explanation:

The chloroplast is responsible for photosynthesis, which is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Which of the following is not a type of tissue?

  1. Epithelial tissue

  2. Connective tissue

  3. Muscle tissue

  4. Nervous tissue


Correct Option: D
Explanation:

Nervous tissue is not a type of tissue. The four main types of tissue are epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

What is the function of the nucleus?

  1. Cellular respiration

  2. Photosynthesis

  3. Protein synthesis

  4. DNA storage


Correct Option: D
Explanation:

The nucleus is responsible for DNA storage. It contains the cell's genetic information.

Which of the following is not a type of organ system?

  1. Digestive system

  2. Respiratory system

  3. Circulatory system

  4. Endocrine system


Correct Option: D
Explanation:

The endocrine system is not a type of organ system. The four main types of organ systems are the digestive system, respiratory system, circulatory system, and nervous system.

What is the function of the kidneys?

  1. Filtering blood

  2. Producing urine

  3. Regulating blood pressure

  4. All of the above


Correct Option: D
Explanation:

The kidneys are responsible for filtering blood, producing urine, and regulating blood pressure.

Which of the following is not a type of organism?

  2. Animal

  3. Fungus

  4. Bacteria


Correct Option: D
Explanation:

Bacteria are not a type of organism. The three main types of organisms are plants, animals, and fungi.

What is the function of the heart?

  1. Pumping blood

  2. Filtering blood

  3. Producing urine

  4. Regulating blood pressure


Correct Option: A
Explanation:

The heart is responsible for pumping blood throughout the body.

Which of the following is not a type of ecosystem?

Correct Option: D
Explanation:

The ocean is not a type of ecosystem. The three main types of ecosystems are forests, grasslands, and deserts.

What is the function of the lungs?

  1. Breathing

  2. Filtering blood

  3. Producing urine

  4. Regulating blood pressure


Correct Option: A
Explanation:

The lungs are responsible for breathing, which is the process of taking in oxygen and releasing carbon dioxide.

Which of the following is not a type of biomolecule?

  1. Carbohydrate

  2. Protein

  3. Lipid

  4. Nucleic acid


Correct Option: D
