A specie is a group of similar organisms who can breed with each other to produce fertile offsping.

How do you name a specie?
By using the binomial system.
3 of 23
What is the binomial system split into?
The generic name which is the genus the specie belongs to and the specific name which is what the specie belongs to
4 of 23
How are binomial names written?
If it's printed, you would use italics, if handwritten you would underline them. Generic is with a capital letter and specific is written with a lower case letter. If the specific is unknown then you write sp.

What is courtship behaviour?
Where an animal attempts to attract the opposite gender
6 of 23
How does courtship behaviour help achieve successful offspring?
- recognise members from their own specie, identify a mate able to breed, form a bond, synchronise mating.
7 of 23
Why do males use courtship behaviour?
To determine whether the female is at a receptive stage.If she responds with the appropriate behaviour, courtship continues and offspring is likely to be produced.

What is taxonomy?
Theory and practice of biological classification.
9 of 23
What are the two forms of biological classification?
Artificial classification and phylogentic classification
10 of 23
What is artificial classification?
Divides organisms according to their differences which are useful at the time eg. colour, shape - analogous characteristics
11 of 23
What is phylogenetic classification?
Based on evolutionary relationships between organisms and their ancestors. It classifies species into groups using shared features from ancestors. Also, arranges the group into hierarchy
12 of 23
What is the highest taxonomic rank?
Domain
13 of 23
What is a taxon?
A group within the phylogenetic classification
14 of 23
What are the 3 domains?
Archaea, bacteria and eukarya
15 of 23
What features does bacteria have?
no membrane bound organelles, ribosomes are smaller (70s), unicellular, cell walls made of murein.
16 of 23
What features does archaea have?
Different to bacteria as genes are similar to eukaryotes, no murein in cell walls,
17 of 23
What features does eukarya have?
They have membrane bound organelles, membranes contains fatty acid chains, ribosomes are larger than bacteria and archaea (80s)

What is biodiversity?
Describes variety in the world. Number and variety of living organisms in a particular area.
19 of 23
What are the 3 types of biodiversity?
species, genetic and ecosystem diversity.
20 of 23
How is species diversity measured?
It's measured using species richness.
21 of 23
What is species richness?
The number of different species in a particular community at a specific time.
22 of 23
What is the index of diversity?
quantitative measure that reflects how many different types there are in a set of data.
