Question

what happens to the uterus and the released egg if fertilisation does not occur?​

Answer 1

If the released egg is not fertilised during a menstrual cycle, the inner lining of uterus breaks down and the secretion of oestrogen and progesterone stops. Because these hormones are no longer present, the lining of the womb starts to fall away and is removed from the body through menstruation.

Answer 2

Answer:

All mosquitoes breed in water. Hence, by keeping the surroundings clean and dry, we can prevent mosquitoes from breeding. We should not allow water to collect in coolers, flower pots, etc. We should wear full sleeves shirts in the evenings and at night. We can also use mosquito repellant creams and mosquito nets.
