The cycle stops while a woman is pregnant. These are the main features of the menstrual cycle:
  • The start of the cycle, day 1, is when bleeding from the vagina begins. This is caused by the loss of the lining of the uterus, with a little blood. This is called menstruation or having a period.
  • By the end of about day 5, the loss of blood stops. The lining of the uterus begins to re-grow and an egg cell starts to mature in one of the ovaries.
  • At about day 14, the mature egg cell is released from the ovary. This is called ovulation
  • The egg cell travels through the oviduct towards the uterus.
  • If the egg cell does not meet with a sperm cell in the oviduct, the lining of the uterus begins to break down and the cycle repeats.
  • Fertilisation occurs in the oviduct.

Cartilage rings in the walls of the trachea help to keep it open and allow flexibility.
•The bronchi split into smaller and smaller tubes called bronchioles. These end in microscopic air sacs called alveoli. There is a muscular diaphragm below the lungs.

•Carbon Dioxide diffuses (moves) from a high concentration in the capillary to a low concentration in the lungs.
•Oxygen diffuses (moves) from a high concentration in the lungs to a low concentration in the blood capillary.

This is usually a green plant, because plants can make their own food by photosynthesis.

A food chain ends with a consumer, which is an animal that eats a plant or another animal. Here is an example of a simple food chain:

grass → cow → human

Take care - the arrow points to the organism that is doing the eating. If you get the arrows the wrong way round, instead of showing that humans eat cows, you are showing that cows eat humans, and that grass eats cows.

Polar bears are well adapted for survival in the Arctic. They have:

  • a white appearance, as camouflage from prey on the snow and ice
  • thick layers of fat and fur, for insulation against the cold
  • a small surface area to volume ratio, to minimise heat loss
  • a greasy coat, which sheds water after swimming.
