Answer:

Reproduction in Australia

1. Fertilization:

  • Fertilization occurs when the sperm and egg come together inside the female's body.
  • The sperm is deposited into the fallopian tube, where it travels through the fallopian tube and into the uterus.
  • Fertilization can also occur in the ovary, but it is more common in the fallopian tube.

2. Ovulation:

  • Ovulation is the release of an egg from the ovary.
  • It occurs when the follicle ruptures and the egg is released into the fallopian tube.
  • Ovulation typically occurs 14 days before the start of a period.

3. Gestation:

  • The fertilized egg travels through the fallopian tube and into the uterus.
  • The embryo implants into the lining of the uterus, where it begins to grow and develop.
  • Gestation typically lasts for about 40 weeks.

4. Parturition:

  • At the end of gestation, the baby is born through childbirth.
  • The baby is then delivered through the vagina or an incision in the abdomen.

5. Lactation:

  • After childbirth, the mother produces milk to feed her baby.
  • Milk production is stimulated by hormones produced by the pituitary gland.
  • The baby nurses on the mother's breast to obtain nutrients.

Additional Notes:

  • Australia has a high rate of sexual reproduction, with an average of 2.5 children per woman.
  • The average gestation period in Australia is 37 weeks.
  • The average age of first pregnancy in Australia is 25.5 years.
