Biology

1. What is the basic unit of heredity?

Correct answer: C

Rationale: Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.

2. What is the difference between the atomic number and the mass number of an atom?

Correct answer: C

Rationale: The atomic number and the mass number are two fundamental properties of an atom. They provide important information about the identity and structure of an element.

6. Which organelle is responsible for breaking down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks?

Correct answer: C

Rationale: Rationale: Lysosomes are membrane-bound organelles containing digestive enzymes that break down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks. These enzymes help in the process of intracellular digestion and recycling of cellular components. The Golgi apparatus is involved in processing and packaging proteins for secretion or for use within the cell. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism.
