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
Cell Wall Presence : Present in: Plants (made of cellulose), Bacteria (peptidoglycan), Fungi (chitin). Absent in : Animal cells (only have a cell membrane).

Explanation
Mitosis Stages: Karyokinesis : Division of the nucleus ( prophase, metaphase, anaphase, telophase ). Cytokinesis : Division of the cytoplasm (occurs after karyokinesis ).

Explanation
The liver is the largest gland in the human body. It is situated in the right upper quadrant of the abdomen , beneath the diaphragm , and above the stomach . The liver is reddish-brown . It is weighs approximately 1.5 kg . Additional information The pineal gland is the smallest gland. It about the size of a grain of rice . It weighs approximately 150 mg. It is part of the endocrine system.

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
He told me that he had been ill. Rules of Narration Change: Reporting Verb : " Said to " → " Told " (more natural in reported speech). Tense Shift : Past (" was ") → Past Perfect (" had been ") (since the original statement was about a past condition). 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."
