What is a pipette? How is it used?
It is a tool used for transferring precise amounts of liquid

Name three environmental factors that can affect development
Diet (alcohol, cigarettes), pollutants (oil, mercury, nitrates), predators, temperature, light etc
300
What type of organism is this?
Tardigrade
300
What are the two ways that plankton get their nutrients?
By creating it themselves (photosynthesis, chemosynthesis) or by eating other organisms (heterotrophic)
300
What feature allows some planktonic organisms to move around
Cilia or flagella

What is the best way for a pregnant person to prevent spina bifida in their baby?
Eat folic acid (vitim b9) before and during the pregnancy
400
What characteristics do scientists use to classify an organism as planktonic?
An organism is considered planktonic if it is carried by water movement and cannot swim against this movement.
400
How does an amoeba move?
By extending and retracting (pulling back) projections of its cell (called psudopods)
400
What makes some algae appear green
Chlorophyll
400
How does a light microscope work?
It uses lenses to bend light towards the eyes and makes the object appear larger than it is

Name three of the groups you could have encountered in your plankton tow
Algae, protozans, animals, monerans, arthropodds
500
Where do plankton digest their food
In food vacuoles (special sacs with digestive enzymes)
500
In a biology lab, what does it mean to "fix" an animal?
To "fix" is to euthanize an animal and preserve its current cell structure and physiology
