group of organisms made up of one or more E cells

19
Q

A

shows the evolutionary relationships between organism

shown by phylogenetic tree

20
Q

What are the sources of evidence for species?

A

DNA
fossil records
homologous features
evolutionary history

21
Q

What is genera?

A

genus

22
Q

What do they mean by hierarchical?

A

larger groups containing smaller groups

23
Q

Why is using fluorescent markers on insects the measuring population size a good idea?

A

ensures no loss to predation as the mark is only visible in UV light

24
Q

When measuring a population size what do you have to assume?

A

the birth rate= death rate

no immigration
