PRACTICAL SKILLS
Add the values, and divide by the number of values you have.
How do you calculate a mean?
The nucleus
Where is DNA stored in a cell?
Communicable
What is a disease that can be passed on to others?
Temperature, concentration and pH
What factors effect enzyme activity?
Double helix structure
What structure does DNA have?
To get reliable results/rule out anomalous results
Why might we repeat an experiment
Respiration
What process occurs in the mitochondria?
Bacteria only
What type of pathogen can be treated by antibiotics?
Something that speeds up a reaction without being used up. Enzymes are an example of these.
What is a catalyst?
complementary base pairing such as A-T and C-G
What is the term given to the way bases join together in DNA?
A number that does not fit the trend of results
What is an anomalous result?
Prokaryotic
What type of cell is bacteria?
Gonorrhoea
Name a sexually transmitted disease
The enzyme becomes denatured and no longer binds to the substrate
What happens when conditions are too hot for an enzyme?
hydrogen bonds
What type of bonds hold together the bases in a double helix?
Something you keep the same in an experiment
What is the control variable?
The site of photosynthesis in plant cells
What are chloroplasts?
Inject a small amount of dead or inactive pathogens
What happens during a vaccination?
carbohydrase enzyme
Which enzyme breaks down carbohydrates into glucose?
A different form of a gene
What is an allele?
So that we can see the structures
Why would you put stain on the slide before placing it under the microscope?
Mitosis
What type of cell division forms 2 genetically identical daughter cells?
Antibiotics
What treatment is there for bacterial infections?
The lock and key model
Which model represents the way enzymes and substrates work?
one forms 4 haploid daughter cells whereas the other forms 2 genetically identical daughter cells
How is meiosis different to mitosis?
