Q6. The honey bees exhibit a type of dance to communicate the location of food. This is known as:
Solution
The honey bees exhibit 2 types of dance to communicate the location of food, the round dance and the tail-wagging or waggle dance.

Q7. Haploid plants are preferred over diploid plants for study of mutation because in haploids:
Solution
Haploids are preferred over diploids for mutation study because in haploids recessive mutation is easier. Most of the induced mutations are recessive and these have to be in double to be expressed phenotypically. Mutations are not seen in heterozygous conditions. So, in haploid plants, recessive mutation express immediately.

Q8. In order to obtained disease free plants through tissue culture methods the best techniques is
Solution
Healthy plants can be recovered from diseased plants by this method. Apical and axillary meristem is the only virus free part of a virus-infected plant. By removing the meristem and growing it in vitro, virus-free plants can be obtained

Q9. In crop improvement programmes, virus-free clones can be obtained through
Solution
Tissue culture technique can be utilized for the production of virus-free plants either by meristem culture chemotherapy or selective chemotherapy of larger explants from donor plants. Shoot apex consists of meristematic-cells, thus shoot apex culture is successful to obtain virus-free clones in crop improvement programmes
