Yeast is essential in making of bread because it produces:

  • (a) Carbon dioxide
  • (b) Bacteria
  • (c) Oxygen
  • (d) Sugar
Check Answer
  • (a) Carbon dioxide
Explanation
  • Yeast is very important in the production of bread. Yeast ferments the sugar in the dough, producing carbon dioxide. The carbon dioxide produced gets trapped in the dough, causing the dough to rise. The dough becomes soft and fluffy.
  • It’s not correct to refer to yeast as “bacteria.” Yeast is a fungus. While bacteria are involved in fermentation in some food products, such as yogurt, yeast fermentation of sugar to produce carbon dioxide to make bread rise doesn’t involve bacteria. The substance that makes bread rise is carbon dioxide, not bacteria.

    After fertilization, a fruit develops from which part of the plant?

    • (a) Ovule Wall
    • (b) Anther
    • (c) Ovary
    • (d) Sepals
    Check Answer
    • (c) Ovary
    Explanation
    In flowering plants, fertilization triggers a chain of changes in the reproductive parts of the flower. The ovary, the swollen part at the base of the pistil, undergoes hormonal and cellular changes to develop into a fruit that protects the developing seeds and later aids in their dispersal.

    Which disease is caused by the deficiency of Vitamin D?

    • (a) Scurvy
    • (b) Rickets
    • (c) Night Blindness
    • (d) All of these
    Check Answer
    • (b) Rickets
    Explanation
    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
    Check Answer
    • (b) 1983
    Explanation
    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
    Check Answer
    • (c) 2:1
    Explanation
    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
    Check Answer
    • (b) Platelets
    Explanation
    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
    Check Answer
    • (c) Chewing
    Explanation
    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.
