    Viruses reproduce inside body cells. Therefore, any attempt at treatment - such as antibiotics - would damage the body cells, and would struggle to reach the pathogens.

    The bacterium can now reproduce rapidly and because people with diabetes can't produce insulin, the bacteria produces it instead, giving the person insulin. This controls your blood sugar levels.

    sperm and egg removed from the prize animal (bull or cow for example), artificially fertilised to cause many embryo's to form, then inserted into a surrogate mother, all of the offspring are genetically identical to one another and therefore you have the ideal offspring.

    They change chemical reactions in the body and therefore the person becomes dependent on the drug and suffers from withdrawal symptoms. This is also due to drugs such as nicotine being highly addictive.

    I think you may have to be more specific:
    A recessive allele's characteristics (phenotype) are only shown if the person has two alleles whereas a dominant allele's characteristics are shown if they only have one allele

    Cholesterol is made in the liver. There are two types : HDL and LDL. HDL is good for the body whereas too much LDL is bad for the body. Cholesterol is needed to produce bile and build up the walls of the blood vessels.
