Q1. What is the function of the mitochondria in a cell?
Answer: The mitochondria are responsible for generating energy (ATP) through cellular
respiration.
Q2. Describe the difference between a hypothesis and a theory.
Answer: A hypothesis is a proposed explanation for a phenomenon, while a theory is a well-
substantiated explanation based on evidence and experimentation.
Q3. What is the role of chlorophyll in photosynthesis?
Answer: Chlorophyll absorbs light energy used to convert carbon dioxide and water into glucose
and oxygen during photosynthesis.
Q4. Name the four main types of tissue found in the human body.
Answer: The four types of tissue are epithelial, connective, muscle, and nervous tissue.
Q5 Explain the difference between asexual and sexual reproduction.
Answer: Asexual reproduction involves a single parent and produces offspring genetically
identical to the parent, whereas sexual reproduction involves two parents and produces
genetically diverse offspring.
Q6 What is the difference between a prokaryotic cell and a eukaryotic cell?
Answer: Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic
cells have both a nucleus and membrane-bound organelles.
Q7 Describe the process of osmosis.
Answer: Osmosis is the movement of water molecules across a semipermeable membrane from
an area of lower solute concentration to an area of higher solute concentration.
Q8 What is the function of the circulatory system?
, Answer: The circulatory system transports oxygen, nutrients, hormones, and other substances
throughout the body and removes wastes.
Q9 Define the term "acceleration" in physics.
Answer: Acceleration is the rate of change of velocity of an object over time.
Q10 Explain how fossils provide evidence for evolution.
Answer: Fossils are preserved remains or traces of organisms from the past that provide a record
of the history of life on Earth and support the theory of evolution by showing changes in species
over time.
Q11 What is the difference between a chemical change and a physical change?
Answer: A chemical change results in the formation of new substances with different properties,
while a physical change alters the form or appearance of a substance without changing its
chemical composition.
Q12 Describe the structure of DNA.
Answer: DNA (deoxyribonucleic acid) is a double helix molecule composed of two strands of
nucleotides that encode genetic information.
Q13 What is the difference between weather and climate?
Answer: Weather refers to the short-term atmospheric conditions in a specific area, while
climate refers to the long-term patterns of temperature, precipitation, and other weather variables
in a region.
Q14 How does the process of diffusion work in cells?
Answer: Diffusion is the movement of molecules from an area of higher concentration to an area
of lower concentration, driven by the concentration gradient.
Q15 Explain the concept of natural selection.
Answer: Natural selection is the process by which organisms that are better adapted to their
environment tend to survive and reproduce more successfully than those that are less adapted,
leading to evolutionary change.
Q16 What are the three main types of plate boundaries?
Answer: The three main types of plate boundaries are divergent boundaries (where plates move
apart), convergent boundaries (where plates move toward each other), and transform boundaries
(where plates slide past each other).
