Explanation

Pinocytosis:

This term means "cell drinking" and refers to the process where a cell engulfs small amounts of extracellular fluid and dissolved substances. 

Explanation

Chromosomes are thread-like structures made of DNA and proteins, found in the nucleus of eukaryotic cells.

They carry genetic information and ensure its accurate distribution during cell division.

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.

Explanation

A biocatalyst is a protein that speeds up a biochemical reaction in a living organism, and the term "enzyme" specifically refers to a protein with this function. 

Explanation

A virus is an obligate intracellular parasite. 

Obligate intracellular parasite:

This means a virus must live inside a host cell to replicate and survive.

Viruses lack the necessary machinery to produce proteins or generate energy on their own, so they rely on the host cell's resources.
