This question requires a basic understanding of lung/chest/diaphragm anatomy.

The body actively tries to hold on to glucose provided it does not exceed a certain concentration in the blood. Glucose is a useful molecule. The graph shows how, up to a certain concentration, all glucose is returned to the blood.
This is a simple graph question. The trick is to realise that solvents T and S move in the direction of the arrows rather than indicating labels for the axes. This is apparent from the question if you read carefully!
This question is about skin grafting.
- Allograft = skin grapt between two mewmbers of a species.
- Autograft = skin graft from one individual to the same individual.
- Xenograft = skin graft between different species
The xenograft is rejected.
- The order of a reaction determines how much faster the reaction will go if the concentration of reactant is increased
- Rate = K[CO2]n
This question requires you to interpret the graph and to understand that Hb saturation is related to the animal’s size. The sigmoid shape shows that atoms 2 and 3 are lost more easily than 1 and 2.
- Meiosis is the process that creates sperm and egg cells.
- Sperm and egg cells have only half the genetic information of a normal cell, they are haploid.
- First the chromosomes replicate as usual.
- Then matched pairs align themselves at their centromeres, some dna may be passed between matched pairs (crossover).
- The cell divides.
- Finally the two daughter cells divide again, leaving one half complement of DNA in each of 4 cells.
