Biology

1. Homologous structures are those that:

Correct answer: C

Rationale: Rationale: - Option A is incorrect because structures with the same function but different origins are analogous structures, not homologous structures. - Option B is incorrect because structures with different functions but the same origin are also not homologous structures; they are considered to be vestigial structures. - Option D is incorrect because structures that are identical in both appearance and function are not necessarily homologous; they could be the result of convergent evolution. Homologous structures are those that share similarities in appearance and function due to being inherited from a common ancestor. These structures may have undergone modifications over time to adapt to different functions in different species, but their fundamental similarities can be traced back to a shared evolutionary history.

2. Balance the chemical equation: C4H10 + O2 → CO2 + H2O. What is the coefficient for oxygen?

Correct answer: b

Rationale: The balanced equation is C4H10 + 6O2 → 4CO2 + 5H2O.

3. What is the difference between a prokaryotic cell and a eukaryotic cell?

Correct answer: B

Rationale: Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.

4. Where should a semicolon be placed in the following sentence? "He loves reading comics, playing video games, and spending time with friends"?

Correct answer: B

Rationale: Semicolons can join three or more items in a list, especially when the items themselves contain commas. Option (b) is the correct placement.

5. When an atom gains or loses electrons, it becomes a(n):

Correct answer: C

Rationale: Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion.

6. What happens to the momentum of an object when there is no external force acting upon it?

Correct answer: c

Rationale: In the absence of external forces, momentum remains constant due to the conservation of momentum.
