8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
Question 1: Animal Tissues
The gap junctions in the animal tissues:
- A form the cement
- B facilitate the cells to communicate with each other by connecting the cytoplasm of the adjoining cells, for the rapid transfer of ions, small molecules and some large molecules
- C seal the tissues
- D secrete the enzymes
Answer: B. facilitate the cells to communicate with each other by connecting the cytoplasm of the adjoining cells, for the rapid transfer of ions, small molecules and some large molecules
Why: They are present in the cardiac muscle.
Question 2: Earthworm as a Representative Organism
The earthworm respires through the:
- A the tracheae
- B the lungs
- C moist skin
- D the gills
Answer: C. moist skin
Why: The respiratory pigment, haemoglobin, is dissolved in the plasma.
Question 3: Frog: Morphology and Anatomy
The frog's body is divided into:
- A the head and the trunk; there is no neck or tail
- B the head, trunk and tail
- C the head, neck and trunk
- D the head and the tail
Answer: A. the head and the trunk; there is no neck or tail
Why: The forelimbs have 4 digits and the hind limbs have 5 webbed digits.
Question 4: Animal Tissues
The cartilage is found in:
- A the skin
- B the tip of the nose, the outer ear joints, the vertebral column and the limbs
- C the skull bones only
- D the blood
Answer: B. the tip of the nose, the outer ear joints, the vertebral column and the limbs
Why: It resists compression.
Question 5: Earthworm as a Representative Organism
The gizzard of the earthworm helps to:
- A store the food
- B grind the soil particles and the decaying leaves to a fine pulp
- C secrete the enzymes
- D absorb food
Answer: B. grind the soil particles and the decaying leaves to a fine pulp
Why: The calciferous glands neutralise the humic acid.
Question 6: Frog: Morphology and Anatomy
The frog undergoes:
- A budding
- B no larval stage
- C metamorphosis, with the tadpole stage
- D direct development
Answer: C. metamorphosis, with the tadpole stage
Why: The tadpole is an aquatic larva that develops into the adult.
Question 7: Animal Tissues
The ligaments attach:
- A the muscle to bone
- B the skin to the muscle
- C one bone to another bone
- D the nerve to bone
Answer: C. one bone to another bone
Why: They are the dense regular connective tissues.
Question 8: Earthworm as a Representative Organism
The typhlosole in the earthworm intestine:
- A increases the effective area of the absorption
- B secretes the enzymes
- C stores the water
- D grinds the food
Answer: A. increases the effective area of the absorption
Why: It is a median fold of the dorsal wall.
