Question 1: Which Organ Filters Urea from the Blood?

Options:
A. The liver
B. The kidney
C. The lung
D. The heart
E. Pancreas

Question 2: Which Disease is Caused by a Protozoan?

Options:
A. Cholera
B. Tuberculosis
C. Malaria
D. Tetanus
E. Measles

Correct Answer: Malaria
Explanation: Malaria is caused by a protozoan known as Plasmodium. Other examples of protozoans include Trypanosoma.

Question 3: What Type of Skeleton is Found in Earthworms?

Options:
A. Exoskeleton
B. Hydrostatic skeleton
C. Endoskeleton
D. Cartilaginous skeleton
E. Bony skeleton

Correct Answer: Hydrostatic skeleton
Explanation: Earthworms have slimy and soft bodies supported by internal fluid pressure, which is referred to as a hydrostatic skeleton.

Question 4: Which Part of the Brain Controls Breathing?

Options:
A. Cerebrum
B. Cerebellum
C. Medulla Oblongata
D. Thalamus
E. Hypothalamus

Correct Answer: Medulla Oblongata
Explanation: The medulla oblongata is the part of the brain that controls vital functions like breathing and heartbeat.

Question 5: What is the Mode of Nutrition in Fungi?

Options:
A. Autotrophic
B. Parasitic
C. Holozoic
D. Saprophytic
E. Chemosynthetic

Correct Answer: Saprophytic
Explanation: Fungi feed on decaying organic matter, making their nutrition mode saprophytic.

Question 6: Where Does Most Photosynthesis Take Place in a Plant?

Options:
A. Roots
B. Stem
C. Leaf
D. Flower
E. Fruit

Correct Answer: Leaf
Explanation: Photosynthesis is the process through which sugar or starch is produced from water, carbon dioxide, and sunlight in the presence of chlorophyll. The leaf contains abundant chlorophyll, making it the primary site of photosynthesis.

Question 7: What Best Describes Osmosis?

(The options begin but cut off. Let’s proceed with the text continuation.)

Options likely include:
A. Movement of solute from higher to lower concentration
B. Movement of water molecules through a semi-permeable membrane
C. Diffusion of gases
D. Active transport process
E. None of the above

Correct Answer: B. Movement of water molecules through a semi-permeable membrane
Explanation: Osmosis refers to the movement of water molecules from a region of lower solute concentration to a region of higher solute concentration across a semi-permeable membrane.
