There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, either solely, but usually by forming a particular tissue. Different tissues then combine and form specific organs, where the organ is like a factory where every type of cell has its own job.
In cell differentiation, the objective is to differentiate cells based on their functions and the organs they are going to form. In this exercise, the cells need to get on and off to define the type of the cell and its function. Hence options A, C is important for cell differentiation. Information from DNA is transferred to mRNA for cell differentiation; hence option D is also correct. While option B has no role in cell differentiation loss of DNA segment could cause mutation i.e. deletion.
Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are Gonadotropins stimulated in the gonads. In females, they are located in the ovaries. They are not needed for life yet important for reproduction. Progesterone which is being secreted in corpus luteum is needed for maintenance of pregnancy thus if a female has a low FSH and LH it will affect the chance of her be pregnant.
