1. A hen sitting on eggs until chicks hatch out is an example of which characteristic of living things?
A. Excretion
B. Movement
C. Reproduction
D. Nutrition
Explanation: Reproduction is the ability of living things to produce new individuals of their own kind. The hen hatching chicks from eggs is an example of reproduction.
2. Plants get rid of excess oxygen and carbon dioxide produced during their life processes mainly through their
A. roots
B. stem
C. leaves
D. flowers
Explanation: Plants excrete waste gases such as oxygen and carbon dioxide mainly through tiny openings called stomata found on their leaves.
3. A small pepper seedling planted in a garden gradually increases in height and number of leaves over several weeks. This shows that the plant is capable of
A. respiration
B. growth
C. excretion
D. irritability
Explanation: Growth is a permanent increase in size and dry mass of an organism. The increase in height and number of leaves of the pepper plant over time is an example of growth.
4. The process by which living things break down food to release energy is called
A. reproduction
B. respiration
C. excretion
D. sensitivity
Explanation: Respiration is the process by which organisms break down food substances, such as glucose, to release energy needed for their life activities.
5. A student touches the leaves of a mimosa (sensitive plant) in the school garden, and the leaves quickly fold up. This shows that the plant has the characteristic of
A. excretion
B. sensitivity (irritability)
C. nutrition
D. reproduction
Explanation: Sensitivity, also called irritability, is the ability of living things to detect and respond to changes (stimuli) in their environment. The folding of the mimosa leaves when touched shows sensitivity.
6. When a student passes out urine after drinking a lot of water, this process is an example of
A. excretion
B. digestion
C. reproduction
D. sensitivity
Explanation: Excretion is the removal of waste products of metabolism, such as urine, from the body. Passing out urine is a common example of excretion in humans.
7. Which of the following is NOT one of the basic characteristics of living things?
A. Growth
B. Melting
C. Respiration
D. Reproduction
Explanation: Melting is a physical change that happens to substances like ice or wax when heated; it is not a characteristic of living things. Growth, respiration, and reproduction are all characteristics of living things.
8. A baby that grows into an adult over many years shows an increase in size and complexity of the body. This process is called
A. excretion
B. growth
C. respiration
D. irritability
Explanation: Growth involves a permanent increase in the size, mass, and complexity of an organism's body over time, as seen when a baby develops into an adult.
9. All living things carry out respiration mainly in order to
A. release energy from food
B. get rid of solid waste
C. produce new offspring
D. respond to light
Explanation: Respiration is the process by which living organisms break down food substances to release energy needed for their life activities.
10. When a goat quickly withdraws its leg after stepping on a sharp stone, which characteristic of living things is it showing?
A. Nutrition
B. Excretion
C. Irritability (response to stimuli)
D. Reproduction
Explanation: Irritability is the ability of a living thing to respond to a stimulus, such as pain from a sharp object. The goat's quick withdrawal is a response to the painful stimulus.
11. A cow chewing grass on a farm in order to obtain nutrients for its body is showing the characteristic of
A. excretion
B. nutrition
C. respiration
D. growth
Explanation: Nutrition is the process by which living organisms obtain and use food materials for energy, growth, and repair. The cow eating grass is obtaining nutrients through nutrition.
12. Which of the following is NOT one of the characteristics shared by all living things?
A. Growth
B. Respiration
C. Rusting
D. Reproduction
Explanation: Rusting is a chemical process that occurs in non-living materials like iron when exposed to moisture and oxygen. It is not a characteristic of living things, unlike growth, respiration, and reproduction.
13. Which of the following is an example of nutrition in living things?
A. A dog barking at a stranger
B. A hen laying eggs
C. A cat eating fish for energy
D. A snail moving slowly on a leaf
Explanation: Nutrition is the process by which living things take in and use food for energy, growth, and repair. A cat eating fish to get energy is an example of nutrition.
14. Which of the following is a non-living thing?
A. A mango tree in a school compound
B. A grasshopper on a leaf
C. A wooden chair in a classroom
D. A tilapia fish in a pond
Explanation: A wooden chair does not show any of the characteristics of living things, such as growth, respiration, or reproduction, so it is a non-living thing, unlike the tree, grasshopper, and fish.
15. A student accidentally touches a hot cooking pot and quickly withdraws his hand. This reaction shows the characteristic of living things known as
A. nutrition
B. irritability
C. excretion
D. reproduction
Explanation: Irritability (sensitivity) is the ability of a living organism to detect and respond to changes (stimuli) in its environment. Quickly withdrawing the hand from a hot pot is a response to a stimulus (heat).
16. Which of the following is a characteristic shown when a goat runs away from a barking dog in a Nigerian compound?
A. Nutrition
B. Movement
C. Excretion
D. Reproduction
Explanation: Movement is the ability of a living thing to change position or location. The goat running away from the dog shows movement, which helps it escape danger.
17. Which of these activities best demonstrates excretion in humans?
A. Passing out urine and sweat
B. Eating pounded yam and soup
C. Growing taller every year
D. Giving birth to a baby
Explanation: Excretion is the removal of waste products formed inside the body of a living organism. Passing out urine and sweat removes waste materials from the human body.
18. Which of the following objects found in a typical Nigerian classroom is a living thing?
A. A wooden chair
B. A potted flower plant
C. A chalk
D. A plastic ruler
Explanation: A potted flower plant is a living thing because it can grow, reproduce, respire and respond to stimuli, unlike the chair, chalk, and ruler which are non-living objects.
19. Which of the following best distinguishes movement in animals from movement in most plants?
A. Animals cannot move at all, but plants can move from place to place
B. Animals usually move their whole body from place to place, while most plants only move parts of their body such as leaves or shoots
C. Only plants can respond to light by moving
D. Animals and plants move in exactly the same way
Explanation: Most animals can move their entire body from one place to another (locomotion), while most plants remain fixed in one place but can move parts of their body, such as leaves turning towards sunlight.
20. A hen laying eggs which later hatch into chicks demonstrates which characteristic of living things?
A. Respiration
B. Reproduction
C. Excretion
D. Movement
Explanation: Reproduction is the ability of living organisms to produce new individuals of their own kind. A hen laying eggs that hatch into chicks is an example of reproduction.
