GCSE Biology AQA

Question 1 of 13

Medal-premium 1

Platelets are small fragments of cells. They help the blood to clot at a wound, preventing excessive bleeding and bruising.

Select one of the following:

  • True
  • False

Question 2 of 13

Medal-premium 1

Red blood cells carry oxygen from the lungs to all the cells in the body. They have a concave shape which means that they have a large surface area for absorbing oxygen. Red blood cells do not have a nucleus however they do contain haemoglobin. In the lungs, haemoglobin combines with oxygen to form oxyhaemoglobin. In body tissues, the reverse happens - oxyhaemoglobin splits up into haemoglobin and oxygen.

Select one of the following:

  • True
  • False

Question 3 of 13

Medal-premium 1

White blood cells are part of the immune system. They help to protect the body from infectious diseases by
a) engulfing pathogens and digesting them
b) producing antibodies which bind to antigens on the surface of pathogens and destroy them
c) producing antitoxins which counteract poisons produced by invading bacteria

Select one of the following:

  • True
  • False

Question 4 of 13

Select one of the following:

  • True

Question 5 of 13

Medal-premium 1

IVF ( in vitro fertilisation ) involves collecting eggs from a woman's ovaries and fertilising them in a lab using a man's sperm. They are then grown into embryos which are transferred to the woman's uterus. A disadvantage of IVF is that there is a risk of multiple births if more than one embryo grows into a baby, which can result in a higher risk of miscarriage.
