Q8. The cone of Gymnosperms represent the
Answer : Option C
Explaination / Solution:
In gymnosperms, male and female cones are formed that produce male and female gametes.The strobili bearing microsporophylls and microsporangia are called microsporangiate or male strobili. The cones bearing megasporophylls with ovules or megasporangia are called macrosporangiate or female strobili. So, cone of gymnosperms represents the reproductive organs.

Histone proteins are the basic packer and arranger of chromatin.
Q10. The law based on theory of probability is
Answer : Option A
Explaination / Solution:
This law has emerged from the mathematical theory of probability. The pith and substance of this law is that the behavior of an individual event may be erratic and imponderable but when a large number of events of same category are considered, a stable behavior emerges.
