Hello, I couldn't find a useful thread for this so I thought I'd create one where we can ask each other exam questions/ask for any help.

I'll start with:
Explain Adult Cell Cloning
Explain Darwin's theory of evolution

Adult cell cloning
1. Take an adult udder cell (skin cell) and extract its nucleus.
2. Take an egg cell and remove the nucleus to get an empty egg cell.
3. Fuse the empty egg cell with the nucleus with an electric shock
4. This produces a fertile egg cell.
5. This develops into an embryo
6. The embryo is then implanted into the uterus of the surrogate mother
7. The surrogate mother gives birth to a clone of the adult udder.

Darwin's Theory of Evolution
Darwin suggested that all living organisms have evolved from simple life forms. His theory was based on the process of natural selection.
Natural Selection
1. All individuals in a species show variation
2. Those how are well adapted to their surroundings will survive (Survival of the fittest) hence live longer
3. As a result they breed successfully
4. The offspring inherits the genetically information which has enables the individual to survive in its surroundings
5. The next generation of the species will inherit the advantageous feature needed for survival

I think it could be to do with evaluation about cloning, but no one knows. Your answers about cloning and Darwin's theory were great, by the way.

Hey you know for shoots growing upwards I thought higher concentration of auxin meant a higher rate of growth on the bottom causing shoot to grow up. However the emphasis was on higher rate of growth with a little bit of growth still on the top

However the specimen paper says growth occurs ONLY on the bottom can you help me I'm not sure

Growth only occurs on the bottom as the auxins are unequally distributed on the lower side. This causes the cells at the lower side to grow more do to a higher auxin concentration.
