  • Question 1
    1 / -0
    Apis is economically important as it produces
    Solution
    Apis mellifera and A. cerena  are the species of honey bee and are economically very important as they have the high yielding capacity. They are used for the production of both honey and wax. Honey is the complex substance made when the nectar and sweet deposits from plants and trees are gathered, modified, and stored in the honeycomb by honey bees as a food source for the colony. Therefore, the correct answer is option C. 
  • Question 2
    1 / -0
    Which of the following secretes honey?
    Solution
    Honey is a sweet food made by honeybees using nectar from flowers. The other main product of honey bees is beeswax. Hence, option A is correct.
  • Question 3
    1 / -0
    Mutation is a
    Solution
     A mutation is a permanent change in the sequence of DNA. Mutations can be caused by external (exogenous) or endogenous (native) factors, or they may be caused by errors in the cellular machinery. Physical or chemical agents that induce mutations in DNA are called mutagens and are said to be mutagenic. Exogenous factors: environmental factors such as sunlight, radiation, and smoking can cause mutations. Endogenous factors: errors during DNA replication can lead to genetic changes as can toxic by-products of cellular metabolism.
  • Question 4
    1 / -0
    Wool is obtained from the fleece of __________________
    Solution
    • Sheep is an animal that has a rich layer of wool over it. It is used for economic purposes. Many blankets, sweaters, jackets, etc are obtained from sheep wool.

    Solution
    Biofortification is the method in which the food is added or supplemented with the required nutrients. The staple crop like rice is fortified to produce the precursor of vitamin A. Golden rice is the transgenic rice in which beta-carotene synthesizing gene psy and crtl are incorporated by the help of genetic engineering. Beta-carotene is the precursor of the vitamin A. The consumption of the golden rice can help to prevent the deficiency disorders due to less intake of vitamin A. 
    Thus, the correct answer is option B. 
  • Question 10
    1 / -0
