For human female which of the following is incorrect?a)Menstrual cycle...
Menstrual cycle takes 28 days on an average:
The menstrual cycle typically lasts around 28 days, but it can vary from person to person. The cycle is measured from the first day of one period to the first day of the next. During this time, the body goes through hormonal changes that prepare the uterus for a possible pregnancy.
Menopause occurs at 45-55 years of age:
Menopause is a natural biological process that usually occurs between the ages of 45 and 55. During menopause, a woman's ovaries stop releasing eggs and she stops having periods. This transition is marked by a decrease in estrogen levels and can come with symptoms like hot flashes, mood swings, and changes in libido.
The eggs released during pregnancy die:
Eggs are released from the ovaries during ovulation, which is a part of the menstrual cycle. If an egg is not fertilized by sperm, it will disintegrate and be absorbed by the body. However, during pregnancy, the eggs do not die. Instead, one of the released eggs is typically fertilized by sperm and develops into an embryo, leading to pregnancy.
Menstruation takes 4 days on an average:
Menstruation, or a period, typically lasts around 4-7 days. This is the shedding of the uterine lining that occurs when an egg released during ovulation is not fertilized. The blood and tissue pass through the cervix and out of the body through the vagina. The duration and flow of menstruation can vary from person to person.
