what does genetic diveristy mean
the number of different alleles (the alternate forms of genes) of all genes and the frequency with which they appear.
1 of 56
What does gene pool mean
collective set of alleles found in a population
2 of 56
what conservation effort is this: species in obvious decline/impacted by human-kind
Historically
3 of 56
what conservation effort is this: Conservation genetics is the application of genetics to preserve species long-term, as dynamic entities capable of coping with environmental change.
new approach
4 of 56
what is the term for this definition: Number of different species represented in an ecological community, landscape or region
Richness
5 of 56
In global richness where is there higher richness
Equator
6 of 56
In global richness where is there lower richness
Poles
7 of 56
what is the term for this definition: Number of individuals from a particular species found in each sample taken
Abundance
8 of 56
what is the term for this definition: Assemblage (or association of populations) of two or more different species occupying the same geographical area and in a particular time
Ecological community
9 of 56
what is the term for this definition: A system that includes all living organisms (biotic factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit.
Ecosystem
10 of 56
what is the term for this defintion: A more diverse ecosystem has more ecological niches, more feeding relationships among organisms, more organisms that capture energy, & more species that recycle organic nutrients into inorganic forms.
Ecological complexity
11 of 56
what is the term for this defintion: Term relates to the structural components of an ecosystem (e.g. vegetation, water, soil, atmosphere and biota) and how they interact with each other, within ecosystems and across ecosystems. Supporting Functions, Regu
Ecosystem function

What is this method of determining the history of life: dating the rocks in which different fossils are found - because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.
Fossil record
13 of 56
What is this method of determining the history of life: Looking at DNA of living organisms: measure how different species are from each other at a molecular level, and estimate how much time has passed since a single lineage split into different species.

34 of 56
what are hox genes (homeobox)
group of related genes that control the body plan of an embryo along the head-tail axis. They are the blueprint for the animal body plan of an embryo.

are hox genes evolutionary conserved
Yes
36 of 56
How many species are there estimated to be
7.7 million
37 of 56
What does sessile mean
An organism is stationary (is often stuck/attached onto something)
38 of 56
What does motile mean
An organism can move around
39 of 56
