Biology

1. What tool helps scientists identify and classify organisms based on their shared characteristics?

Correct answer: C

Rationale: Rationale: A) Binomial nomenclature is a system used to give each organism a two-part scientific name (genus and species) but does not help in identifying or classifying organisms based on shared characteristics. B) Cladistics is a method of classification based on evolutionary relationships and shared characteristics, but it is not a tool used for identifying organisms. C) Dichotomous key is a tool that helps scientists identify and classify organisms based on their shared characteristics by presenting a series of choices leading the user to the correct identification. D) Domain-based classification is a system of classification that groups organisms into three domains (Bacteria, Archaea, Eukarya) based on molecular and genetic similarities, but it is not a tool used for identifying organisms based on shared characteristics.

2. What is the difference between constructive and destructive interference of waves?

Correct answer: B

Rationale: Constructive interference occurs when peaks of two waves overlap, resulting in a higher combined amplitude. Destructive interference happens when peaks and troughs overlap, cancelling each other out and reducing the overall amplitude.

3. Which type of cell has a nucleus but lacks membrane-bound organelles?

Correct answer: B

Rationale: The correct answer is B: Prokaryotic cell. Prokaryotic cells are characterized by having a nucleus, known as the nucleoid, which contains genetic material but lacks a membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Plant and animal cells (options A and C) are eukaryotic cells that have a nucleus and membrane-bound organelles. Fungal cells (option D) are also eukaryotic cells with a nucleus and organelles. Understanding the difference between prokaryotic and eukaryotic cells is essential in biology to grasp the diversity of cell structure and function.

4. A population refers to a group of organisms of the same:

Correct answer: A

Rationale: In ecology, a population is a specific group of organisms of the same species living in a particular geographic area at a given time. They share a common gene pool and interact with each other and their environment.

5. A common indicator used to distinguish between acidic and basic solutions is:

Correct answer: B

Rationale: Phenolphthalein turns pink in basic solutions and remains colorless in acidic solutions

6. Which sentence uses the colon correctly?

Correct answer: A

Rationale: Colons are used to introduce a list or explanation that follows an independent clause. Options (a) and (c) use the colon correctly.
