I+ OC L+ Constitutive
I+ OC L+, F’ Constitutive
I- O+ L+, F’ Inducible
Is O+ L+ no transcription
Is O+ L+, F’ no transcription
Answer:
The correct answer will be option-A.
Explanation:
The females carry two X-chromosomes in their cells but one of these X-chromosome gets permanently inactivated during embryonic development.
The X-inactivation is known as lyonization which ensures that only one functional X-chromosome should be present like in males. This process is a random process and therefore a female can have both the functional X-chromosomes and males can also have a functional X-chromosome.
Thus, option-A is the correct answer.

Answer:
Option (C)
Explanation:
Sedimentary rocks are those rocks that are formed due to the compaction and lithification of sediments.
When the rocks are weathered by the agents such as wind, water and ice, the sediments or the particles are carried from that particular area to a different place. The sediments are then continuously deposited in a different place. As a result of which the sediments are accumulated over one another, forming layers. These sediments over a due course of time undergoes compaction and solidification due to the weight of the overlying rocks. This is how the sedimentary rocks are formed. Some of the examples of sedimentary rocks are sandstone, limestone, shale, and mudstone.
Thus, the correct answer is option (C).
