What is the male part of the flower?
Bonus 50 points if you can name the part on diagram correctly:
The Stamen
Remember MEN for the male part
200
The point mutation that results in an amino acid being changed to a stop codon.
Nonsense
200
Fungal pathogen that affects Eucalyptus plants
P. cinnamomi
200
A muscle or gland that produces a response in a negative feedback loop
Effector

What is it called when both alleles are expressed, creating a new phenotype?
Codominance
400
The type of cell divison that results in two daughter cells which have the same number and kind of chromosomes as the parents
Mitosis
400
Where do somatic mutations occur?
In non-reproductive body cells (somatic cells)
400
3 examples of barriers in the 1st line of defence
Skin, mucous membrane, cilia, stomach acid, alkali in small intestine, tears & sweat
400
What is Scurvy?
A disease caused by a lack of vitamin C in the diet, causing collagen to not be made properly.
400
What are two examples of agricultural transgenic species?
Golden Rice & BT Cotton
600
What produces the hormone HCG during pregnancy?
The blastocyst or embryo
600
An unpredictable chance event which results in changes in allele frequencies from one generation to the next
Genetic drift

How do you calculate prevalence?

What is the optic nerve?
Consists of bundles of sensory neurons; the image formed in the retina is turned into an electrical message and is transmitted as impulses to the brain
600
What is this technology called?
Bone Conduction Implant
800
What kind of inheritance is this?
Autosomal Recessive
800
Process of SCNT
1. Somatic cell is taken from an individual to be cloned
2. Nucleus is transferred to a donor egg that has had it's nucleus removed (enuculated egg)
3. Electricity fuses the somatic cell and enuculated egg together
4. Specific chemicals are used to stimulate mitosis
5. After mitosis occurs, it is implanted into a surrogate mother
6. Surrogate gives birth to an indentical clone.
800
What kind of pathogen is this?
Amoeba - Protozoa
800
Which visual disorder is this and what treatment is available?
Myopia
Glasses or laser eye surgery can be used as treatment
800
What treament is this an example of?
Bypass Surgery:
Veins from other parts of the body are removed and placed in an area to bypass the blocked artery. This restores blood flow around the blockage

Process of Budding
1. A bud develops on the surface of the year cell of the hypha
2. Nucleus of the parent cell divides; one of the daughter nuclei migrates into the bud and the other remains in the parent cell
3. The individual bud pinches off the parent cell and becomes an individual yeast cell

Process of recombinant DNA & Example
Example: Insulin (medical usage)
1. DNA fragment is isolated and grown in a lab
2. Plasmid vector is isolated from a bacterial cell
3. DNA and plasmid are treated with the same restriction enzyme, cutting them both at a recognition site, creating sticky ends.
4. Complimentary sticky ends attach to eash other through base pairings and DNA ligase is used to seal them both (annealing)
5. Plasmid is returned to the bacterial cell and then is allowed to reproduce in a fermenter with the selected DNA inside.

How do you identify the organism that causes a specific disease?
1000
What is the negative feedback loop when blood glucose levels decrease?
Alpha cells in the pancreas detect the change in BGL (receptor)
Alpha cells instruct pancreas to release glucagon (hormone)
Glucagon breaks down glycogen, so it can be released as glucose into the bloodsteam
BGL then increases (response)

What is Flystrike and the effects?
Flystrike is a disease that animals can receive that is caused by blowflies. It creates a strike in a sheep making a damaged wound, attracting other flies to the wound, allowing them to lay their eggs in said wound.
Effect: Cost Aus sheep industry $280 mil each year, loss of productivity from animal affected meaning less profit
