An organism has cell walls of chitin, no chlorophyll, stores carbohydrate as glycogen and reproduces by means of spores without flagella. What is its kingdom?
If seeds of an unknown species of plant are discovered, what assumption can be made about the species?

Isolated communities in rural Finland, Hungary and some of the Scottish islands have a high incidence of red-green colour blindness. Describe the inheritance of red-green colour blindness.
The human hand is an example of adaptive radiation. Outline adaptive radiation.
Explain how the human body defends itself against pathogens.
Cladograms can be created by comparing DNA or protein sequences. The cladogram on the left is based on DNA sequences and the cladogram on the right is based on comparing protein sequences.
What is the reason that cladograms based on DNA sequences are more reliable predictors of the phylogenetic relationship of species than cladograms based on protein sequences?
