B Marsupials are most common in South America.
C Most of the world’s marsupials live in Australia.
D A horse is a common example of a marsupial.

The first level of organisation where biological life can happen is the ______________. (Choose from: atom, molecule, organelle, cell, tissue, organs, system, organism, population, ecosystem).
the cell
In a microscope, if light travels through a lens of magnification x10 and then through a lens of magnification x20, the overall magnification will be:
x200
The mitochondria in cells produce energy by a process called...
Respiration
Which two elements are needed for the mitochondria to produce energy?
Oxygen and Glucose
In which of these groups do you expect to find the greatest number of other animals?
A Class. B Family. C Order. D Phyla.
D Phyla.
Write the following in order from smallest to biggest: organism, cell, system, organ, tissue.
cell, tissue, organ, system, organism
Apart from the common light microscope, what's the other most frequently used type of microscope, and why would you use it instead of the light one?
Electron microscope. Used to look at even smaller things which cannot be seen with a regular light microscope.
Name 4 of the 7 characteristics of biologically living organisms
Any of the following: Is made of cell(s), Has DNA (genetic information), Homeostasis (maintains some body conditions stable), Reproduce, Grows (develops), Responsive (to environment), Energy (uses and transforms energy).
Which of the following is one of the biggest differences between plant and animal cells?
A The presence of a cell wall
B The position of the nucleus
C The presence of cytoplasm
D The presence of a cell membrane
A The presence of a cell wall
Name five of the seven levels of classification
Any five out of: kingdom, phyla, class, order, family, genus, species.
Explain what is meant by "multicellular organisms have specialised cells".
In multicellular organisms cells develop to perform specific functions or jobs, as opposed to unicellular organisms where the one cell has to perform all functions by itself.
The field of view (the diameter of the image in the microscope) gets smaller when the magnification
A) decreases B) increases
C) remains the same
B) increases.
The more we 'zoom in', the smaller the size of things we look at.
How are respiration and breathing different?
Respiration: production of energy, typically with the intake of oxygen and the release of carbon dioxide.
Breathing: the process of taking air into and expelling it from the lungs. It's the process by which some animals (terrestrial vertebrates) take in oxygen and exhale CO2.
Breathing provides what we need in order to respire.
Both ribosomes and golgi bodies deal with proteins in cells. What's different in their function?
Ribosomes: are the protein 'assembly line' or 'factory'.
Golgi bodies: 'processing' and packaged proteins to be used or 'shipped' outside the cell.
Which two of these plants are likely to have the greatest number of similar features? Explain why.
A Diospyros ebenum
B Diospyros virginiana
C Pinus virginiana
A and B because they have the same genus ('last name'), whereas the virginiana share the same 'first name', but not the same 'family name'.
