Science - Fractional Distillation, Microscopy & Magnification

How does fractional distillation separate a mixture of liquids

Heat to vapour, cool and condense using different boiling points

What are the limitations of a light microscope?

Limited magnification and limited resolution. Cannot see fine detail

Why are electron microscopes better than light microscopes?

Great magnification and greter resolution

What if the formula for magnification?

Magnification = Size of Image / Real Size of Object

What formula isolates Actual Size of Object

Actual Size of Object = Image size / Magnification

What formula isolates Image Size of Object?

Image size = Magnification x Actual Size

Define variation

Differences in characteristics between individuals

What are alleles?

Inherited genetic variants

An example of environmental variation?

Language spoken?

An example of a characteristic caused by a combo of genetics and environment

Height

How do most genetic mutations affect phenotypes?

Most have no affect on phenotypes

When can a new phenotype caused by a mutation be useful

To survive viruses, or changes in an enironment

How to convert millimetres (mm) to micrometres µm

x 1000

Units of sized used in microscopy smallest to largest?

millimetre - micrometre - nanometre

What is resolution?

Ability to distinguish between two separate points close together

In fractional distillation column where is the hottest and where is the coolest

Hottest = bottom Coolest = Top

Where do large molecules with high boiling points and small molecules with low boiling points go?

Large = They condense near bottom Small = Rise to the top to condense

Phenotype

Physical, observable characteristic like colour of eyes

Genotype

specific combo of alleles (genetic code)
