36How can cloned offspring be produced using embryo transplants?
- AAn unfertilised egg cell is taken and the nucleus is removed and a nucleus from an adult body cell is inserted into the empty egg cell. An electric shock is given to make the embryo divide. When the embryo is a ball of cells it is implanted into a surrogate mother to grow into a clone of the original adult body cell.
- BSperm cells are taken and used to artificially fertilise an egg cell. The embryo that develops is split many times (to form clones) before any cells become specialised. The cloned embryos are implanted into surrogate mothers to form genetically identical offspring.
- CPlant cells are taken and put in a growth medium with hormones to grow into new plants, which are clones of the parent plant.

- AVerdadero
- BFalso
38What was Charles Darwin's theory as to how evolution occurs?
- AIndividuals show variation and organisms with beneficial characteristics are more likely to survive and reproduce, passing on their genes and increasing population with this characteristic (natural selection)
- BIf an organism uses a characteristic a lot then, within its lifetime, it would become more developed - the acquired characteristics would pass on to the next generation
39A mutation is always beneficial to an organism
