After fertilization, a fruit develops from which part of the plant?
- (a) Ovule Wall
- (b) Anther
- (c) Ovary
- (d) Sepals

Which disease is caused by the deficiency of Vitamin D?
- (a) Scurvy
- (b) Rickets
- (c) Night Blindness
- (d) All of these
- (b) Rickets
Rickets happens when there’s a lack of Vitamin D over a long period of time. Vitamin D is a vitamin that’s needed for the intestines to absorb calcium and phosphorus. Without enough Vitamin D, the bones can’t get the right balance of minerals, causing them to weaken. In adults, this condition is known as osteomalacia.
Scurvy comes about as a result of a lack of Vitamin C, also known as ascorbic acid.
Night blindness comes about as a result of a lack of Vitamin A, also known as retinol.
The largest famine hit Ethiopia in:
- (a) 1980
- (b) 1983
- (c) 1990
- (d) 1993
- (b) 1983
The 1983-1985 period saw Ethiopia face its worst famine in recent history. The number of casualties is estimated to vary widely, ranging from 300,000 to more than a million. The total number of those affected was about 7.75 million, with 2.5 million displaced within the country and about 400,000 fleeing the nation. Although a severe drought was the initial cause of the disaster, it was further compounded by civil strife and government actions.
The medians of a triangle cut each other in the ratio:
- (a) 4:1
- (b) 3:1
- (c) 2:1
- (d) 1:1
- (c) 2:1
In any triangle, medians intersect at a point that is called the centroid. The centroid divides a median into two segments, and the segment that connects the vertex to the centroid is twice as long as the segment that connects the centroid to the midpoint of the opposite side, or a ratio of 2:1.

Which among the following is responsible for the clotting of the blood?
- (a) Erythrocytes
- (b) Platelets
- (c) Basophils
- (d) White Blood Cells
- (b) Platelets
Platelets, or thrombocytes, are the primary actors that initiate clotting. The clotting, or coagulation, process is a complex of steps that revolves around a few fundamental components:
– Platelets: Platelets are small cell fragments that respond to a bleeding vessel by sticking together to create a temporary platelet plug.
– Clotting factors: These include proteins such as fibrinogen and prothrombin. Thrombin, which is an enzyme, is used to transform fibrinogen into insoluble fibrin threads that provide clotting support.
– Vitamin K: Vitamin K is an essential nutrient that allows the liver to produce some of the clotting factors that are required.
– Calcium ions: These ions act as an essential cofactor.
Mastication is called the process of:
- (a) Digesting
- (b) Grinding
- (c) Chewing
- (d) Swallowing
- (c) Chewing
Mastication refers to the process of chewing, which is the initial stage of digestion where food is physically broken down into smaller pieces by the teeth and mixed with saliva. This mechanical process forms a bolus, increases the surface area of food for enzyme action, and prepares it for swallowing.
