9.
Wind, water and animal are agents of ______________
Correct Answer
B. Dispersal
Explanation
Wind, water, and animals play a crucial role in the dispersal of seeds and spores. They help in carrying the seeds or spores away from the parent plant to new locations where they can germinate and grow into new plants. This process of dispersal increases the chances of survival for the seeds and spores as it allows them to spread out and colonize different areas. Therefore, the correct answer is dispersal.
10.
From which part of the plant sweet potato grows?
Correct Answer
A. Roots
Explanation

11.
Which disease caused by deficiency of iron?
Correct Answer
B. Anaemia
Explanation
Anaemia is a disease caused by a deficiency of iron. Iron is necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. When there is a lack of iron, the body is unable to produce enough healthy red blood cells, leading to symptoms such as fatigue, weakness, and pale skin. Therefore, anaemia is the correct answer for the disease caused by iron deficiency.
12.
Which disease is caused by deficiency of vitamin B1?
Correct Answer
A. Beriberi
Explanation
Beriberi is a disease that is caused by a deficiency of vitamin B1, also known as thiamine. This vitamin plays a crucial role in the metabolism of carbohydrates, and its deficiency can lead to symptoms such as muscle weakness, fatigue, nerve damage, and cardiovascular problems. Beriberi is commonly found in populations that consume a diet mainly consisting of polished rice, as the milling process removes the outer layer of the grain, which is where thiamine is primarily found. Therefore, the correct answer is Beriberi.
13.
Which food item has calcium?
Correct Answer
C. Milk
Explanation
Milk is the correct answer because it is a well-known source of calcium. Calcium is an essential mineral for the development and maintenance of strong bones and teeth.
