Biology

1. What is the significance of studying pedigrees in human genetics?

Correct answer: B

Rationale: Rationale: Pedigrees are diagrams that show the relationships within a family and can be used to track the inheritance patterns of specific traits or diseases. While pedigrees can provide information on the inheritance of single gene disorders (such as identifying carriers of dominant genetic disorders, as mentioned in option C), their primary significance lies in studying complex traits with multiple contributing genes. These traits do not follow simple Mendelian inheritance patterns and are influenced by both genetic and environmental factors. By analyzing pedigrees, researchers can identify patterns of inheritance for complex traits, such as polygenic diseases or traits influenced by gene-environment interactions. Therefore, option B is the most appropriate choice as it captures the main significance of studying pedigrees in human genetics.

2. A solution is formed when:

Correct answer: A

Rationale: One substance dissolves in another. A solution is a homogeneous mixture where one substance (solute) dissolves in another (solvent).

3. Which functional group is commonly found in ketones?

Correct answer: B

Rationale: Ketones have the functional group -CO-, which is a carbonyl group. The other choices are associated with different functional groups

4. Which orbital can hold a maximum of 8 electrons?

Correct answer: C

Rationale: d orbital - Each d orbital can hold a maximum of 2 electrons, and there are 5 d orbitals, totaling 10 possible electrons.

5. What happens to the kinetic energy of an object when its mass is doubled?

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's mass when its velocity remains constant.

6. Which sentence uses the semicolon correctly?

Correct answer: B

Rationale: Option B joins two independent clauses related to the same event.
