Explanation

Reproduction ensures the continuation of a species by passing genetic material to offspring.

It maintains biodiversity and helps species adapt to environmental changes.

Explanation

Enzymes (e.g., ribosomes, polymerases) catalyze the assembly of proteins from amino acids during translation.

While enzymes assist in building various biomolecules, their most direct and universal role is in protein synthesis.

Explanation

Mitosis Stages:

Karyokinesis: Division of the nucleus (prophase, metaphase, anaphase, telophase).

Cytokinesis: Division of the cytoplasm (occurs after karyokinesis).

Explanation

• Omnivores are animals that eat both plants and animals.
• They have adaptations that allow them to digest and extract nutrients from a wide variety of food sources, including fruits, leaves, insects, small animals, and even carrion.
• Examples of omnivores include humans, bears, pigs, chimpanzees, and raccoons.
• Only plants: Herbivores (e.g., cows).
• Only animals: Carnivores (e.g., lions).

Explanation

Active Transport:

Requires energy (ATP) to move molecules against the concentration gradient (low → high).

Example: Sodium-potassium pump in cells.

Explanation

Ecology involves the study of animals and their interactions with the environment.

It covers how organisms adapt, survive, and relate to each other and their surroundings.

Pronoun Shift: "I" → "he" (to match the subject "He").

Explanation

In past tense questions, the auxiliary verb "did" is used, followed by the base form of the main verb ("park").

Correct structure: "Where did you park the car?"

Explanation

The correct phrase is "afraid of", meaning to fear something.

Example: "She is not afraid of death."
