To grow bacteria on agar plates, what temperature should an incubator be set at?
25-40 degrees (anything warm without being too hot)

Which foundation best relates to the onset of puberty?
The driving force of all organisms is to survive and reproduce.

What is the endoplasmic reticulum physically connected to?
The nucleus
200
Which stage of mitosis sees the chromosomes line up in the middle of the cell?
Metaphase

What conditions do bacteria grow best in?
Warm and moist conditions.

When spreading an agar plate with a swab, do you have to cover the whole plate?
Yes
300
Which foundation best relates to the subconscious reflex that keeps us breathing?

What pushes a plant cell wall out to keep it rigid?
A full large central vacuole
300
Chromosomes are replicated (doubled) during which phase of mitosis?
Interphase

What would there be more of on Earth - bacteria, small multicellular organisms, or large multicellular organisms?
Bacteria
300
When measuring bacterial growth on an agar plate, what units is the growth given in?
cm3

Which foundation best relates to a sugar glider having webbed limbs that help them "fly"?
All natural structures aim to meet a function.
400
Are ribosomes only found on the rough ER?
No, they are also found in the cytoplasm
400
In cytokinesis, are the daughter cells identical or just a little bit different?
Identical
400
Where would there be more bacteria (theoretically):

On a dirty dish cloth that had dried.

On a dirty dish cloth that was still a bit damp.

The damp cloth

If a student was looking through a microscope (which has a 10x eyepiece) and used the 40x objective, what would total magnification be?
400x
500
What foundation best relates to the fact all humans (multicellular organisms) originally arose from a single cell?
Cells are the functioning units of all living things.
500
What are the levels of organisation in a multicellular organism?
Organelles -> Cells --> Tissues --> Organs --> Organ systems --> Organism
500
Draw the cell during telophase.
Answers will differ, but should show the cell beginning to narrow in the middle (peanut shape) and the chromosomes already at each end.

Two athletes were completing the same strenuous workout, but in different gyms.  Athlete 1 was working out in an airconditioned gym.  Athlete 2 was working out in an un-airconditioned gym.


At the end, they both throw their dirty gym clothes into a bag and take them home.  They arrive home 30mins later - which athlete had the most bacterial growth in their bag?

Athlete 1 - more sweat

A group of students were growing bacteria in a series of sugar solutions.  They put a different amount of sugar on each agar plate, and measured the growth over two weeks.  What was the independent variable in their experiment?
Sugar amount (variable that was changed).
