Biology

1. What is the scientific name for the tear gland?

Correct answer: A

Rationale: The lachrymal gland is the almond-shaped gland located above each eye, responsible for producing tears. Tears are a complex mixture of water, electrolytes, proteins, and other substances that help lubricate and protect the eyes from dryness and irritation.

2. A triangular scarf has sides measuring 10cm, 12cm, and 15cm. What is its perimeter?

Correct answer: C

Rationale: Simply add the lengths of all sides: perimeter = side1 + side2 + side3 = 10cm + 12cm + 15cm = 37cm.

3. Which of the following properties is NOT characteristic of a covalent bond?

Correct answer: B

Rationale: Covalent bonds are formed by the sharing of electrons between atoms. This sharing results in the formation of molecules with directional bonding, where the atoms are held together in a specific orientation. Covalent compounds generally have low melting and boiling points compared to ionic compounds, as the intermolecular forces in covalent compounds are weaker. Additionally, covalent compounds do not conduct electricity in the solid state because the electrons are localized between the atoms and not free to move and carry charge.

4. What happens to the density of a substance if its mass increases while its volume remains constant?

Correct answer: a

Rationale: Density is the ratio of mass to volume. If the mass increases while the volume remains constant, the density will increase as there is more mass in the same volume.

5. Which of the following is NOT a function of the skeletal system?

Correct answer: A

Rationale: The correct answer is A. The skeletal system provides support and structure to the body, allowing for movement and protecting internal organs. The production of red blood cells occurs in the bone marrow, which is a function of the skeletal system. Additionally, the skeletal system stores minerals like calcium, which play a crucial role in bone health and overall bodily functions. Insulation of the body is not a primary function of the skeletal system but is rather a function of adipose tissue and the integumentary system. Therefore, option A is the correct answer as it does not align with the functions of the skeletal system.

6. What is the functional group present in amines?

Correct answer: C

Rationale: Amines have the functional group -NHâ‚‚. The other choices are associated with different functional groups.
