classification + biodiversity

eq

Domain, kingdom of humans , cellular basis for classification into kingdom

Domain: eukaryotes

Kingdoms: animal

Cellular basis of classification into kingdom: no cell wall

Domain, kingdom of yeast , cellular basis for classification into kingdom

Domain: eukaryote

Kingdom: fungi

Cellular basis for classification into kingdom: yeast has chitin cell wall

Using data state which site has greatest biodiversity

-species richness is the same for both sites

-one site is dominated by 1 species, the site that is more biodiverse has more evenness in the size of each population

Name the statistical test that could be used to compare biodiversity of the two sites

Simpson’s index

Results shown for monitoring two different sites along 2km stretch of coastline for phytoplankton , two sites show significant variation in distribution of phytoplankton , suggest improvement to sampling method to further investigate biodiversity along stretch of coastline

Sample in more locations along coastline , sample more than once a day (more frequently)

Increase sample size (use large diameter/ bigger net)

Chart shows average water temp at sampling site for different months, explain why monitoring takes place more frequently between march and sep

Average water temp is higher so there is higher reproduction/ growth rate of orgs

Analogous structures meaning

Analogous structures evolve separately , are different structures to perform a similar function

Arise through convergent evolution

Homolgus structures meaning

Evolve from a common ancestor, similar structure performing different functions

What are anologus features not considered as

Not Evidence of common ancestry, they arise through convergent evolution

Identify the domain in which giant pandas would belong giving reason

Eukaryote

Membrane bound organelles, DNA bound in nuclear envelope, 80S ribosomes

Define the term biodiversity

The number of different species (species richness) and the number of individuals of each species (species evenness)

Describe a suit ale method which would be used to collect the data needed to estimate plant biodiversity

Place 2 tape measures at right angles to form the axes of a grid

Use a calculator or computer to generate random coordinates

Place the corner of the Quadrat at the point indicated on the grid

Count the number of plant species and the number of plants of each species within each quadrat

Repeat and calculate a mean
