Investigating Flashcards
Variables to control consider all
- gender
- ethnicity
- age group
Fitness levels - no other medications
No. Of subjects per group
Same dosage and medication
Fluid intake/ diet
Previous medical history
Methodology
numbered steps/ logical sequence
- equipment used
- how variables have been controlled
- how results have been significantly measured
- number of trials and repitition
- should be detailed and include a diagram
Analysis and conclusions
Any noticeable trend in the results
-what happens to the dv as the iv increases or decreases
Give evidence to support
Reasons for outliers
- Dont forget to compare between the experimental and the control group
- do the results support/refute hypothesis
Secondary data
used to prove the accuracy of the investigation
- another person needs to have followed the same procedure and have come up with similar results.
Literature review
Looking if the experiment has been done before and this can help in developing the procedure and find secondary data which can support or provdide an alternative to the data collected in the current investigation
Homolougous chromosomes
pair of chromosomes identical in shape and size
Pure breeding
organisms that produce the same characteristics in each succeeding generation when bred amongst themselves ( homozygous)
Hybrid
an offspring that results from mating two individuals with different genetic constitutions ( heterozygous)
Dominant trait
characterisitc of shown by a hybrid
Recessive trait
the characteristic masked by the dominant trait
Genotype
Set of genes ( alleles that a perosn posseses
Allele
The alternative form of the gene
Phenotype
the physical characterisitc expressed by the perosn based on their genotype
Dominant recessive inheritance
