General Science MCQs Answers
S1. Ans.(b)
Sol. The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation.
S2. Ans.(c)
Sol. Scurvy is caused due to deficiency of Vitamin C.
S3. Ans.(d)
Sol. Achras sapote is the scientific name of Chiku.
S4. Ans.(a)
Sol. Prawn belongs to the phylum Arthropoda
S5. Ans.(a)
Sol. The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure.
S6. Ans.(c)
Sol. Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans.
S7. Ans.(a)
Sol.The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
S8. Ans.(a)
Sol. A legume is a plant or its fruit or seed in the family Fabaceae.

S11. (a)
- Early blight of potato is a disease caused by fungus, alternaria solani. It results in the reduction of tuber yield.
S12.(c)
- Mycology is the study of fungus including their genetic and biochemical properties. Pier Antonio micheli is known as the father of the modern Mycology.
S13. (a)
- False fruit are those fruit which are not developed from ovary. Here apple is developed by thalamus. So it is considered as the false fruit.
S14. (a) oxygen liberate after the splitting of water molecule into hydrogen and oxygen. In the photosynthesis this liberate oxygen in atmosphere.
S15. (d)
- Glucose and fructose are primary unit of sugar and gets converted to alcohol by the process of fermentation. Enzyme Zymase helps in the process of conversion.
