1. Ans.(a)
Vermiculture is the process of managing and cultivating earthworms. Earthworms can help turning organic waste into nutrient-rich soil for your garden.
2. Ans.(d)
The scientific study of old age, the process of aging and the particular problems of old people is called Gerontology.
3. Ans.(d)
Genetics is the study of genes, heredity and genetic variation in living organisms.
4. Ans.(d)
The Mesozoic Era is the age of the dinosaurs and lasted almost 180 million years from approximately 250 to 65 million years ago. This era includes three well known periods, called the Triassic, Jurassic and Cretaceous periods.
5. Ans.(d)
Poison gland of snakes is homologous to salivary glands of vertebrates. Snake venom is actually the refined from of its saliva.
6. Ans.(b)
A succulent is a plant that stores water for times when water is not available to it. Succulent plants are generally found in arid environments such as deserts and semi-deserts.
7. Ans.(a)
Phloem transports food from the leaves to the rest of the plant while xylem transport water and solutes from leaves.
8. Ans.(a)
Pasteurization is the heat-treatment process that destroys pathogenic microorganisms in certain foods and beverages. It is named after the French scientist Louis Pasteur.It is used to stabilize and remove disease from milk.
9. Ans.(b)
Cockroach cannot survive in the water because its respiratory organ is trachea.
10. Ans.(d)
Spiny ant-eater is an egg laying mammal.
11. Ans.(c)
