Question

Choose the odd one in each of the following:
Relaxin; cervix dilates; amniotic sac ruptures; childbirth; the follicle.

Answer 1

Here the odd one out is 'follicle' as all other terms are related to childbirth and delivery.

An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle. Women begin puberty with about 400,000 follicles, each with the potential to release an egg cell (ovum) at ovulation for fertilization. These eggs are developed once every menstrual cycle.
