What is ecology
Ecology is the study of living things and their interaction with the environment
100
What is a macromolecule?
A molecule made of many atoms bonded together
100
What are cells?
The basic units of life
100
What is the plasma membrane?
A thin flexible barrier that protects the cell
100
When we are graphing information over time, what kind of graph do we use?
Line graph
200
What is a food web?
A connection of relationships that shows which animals feed on each other
200
What are the elements that make up all living things?
CHNOPS
200
What are two types of cells and define each
Eukaryotic cells are cells with a nucleus and membrane bound organelles, prokaryotic cells have no nucleus
200
What are the parts of the plasma membrane?
Phospholipids, cholesterol and protein
200
How do we phrase a hypothesis?
If - then - because
300
What is an invasive species and how does it damage the food web?
It is a species that is brought in from another area that harms an ecosystem
300
List and describe the four types of macromolecules
Carbohydrates - quick energy, protein - structure and function, lipids - energy storage, nucleic acid - genetic material
300
What are three things plant cells have but animal cells don't?
Chloroplasts, cell wall, large vacuole
300
What is one function of the plasma membrane
To protect the cell, to only let certain things in and out
300
What is the independent variable and what is the dependent variable?
Independent variable is what you change and dependent variable is what you measure
400
Explain three threats to biodiversity
urbanization, deforestation, invasive species, hunting, farming, elimination of food sources, disease
400
Describe the structure of monosaccharides and give an example
Ring structure made of CHO, glucose, galactose, fructose
400
What is the word for when the membrane only lets certain things in and out of the cell?
Selectively permeable
400
What three things do you have to have on a graph?
Title, label your axises, include a key
500
What is a keystone species and how does it keep the food web in balance?
A keystone species is a top predator in the food chain. It keeps the food web balanced. Without it, the secondary consumers eat all the producers and the food web collapses

Sphingosine-1-phosphate is an important biological model in HUMAN pericyte CELLs. What elements is sphingosine-1-phosphate made of?
CHNOPS
500
If a student finds a cell under a microscope and notes that it has a nucleus surrounding its DNA, what kind of cell is he looking at?
Eukaryotic
500
Describe the fluid mosaic model
The plasma membrane lets things move around in the phospholipid bilayer, and it is made of many macromolecules, making it a mosiac
500
Why did we need to do positive and negative tests in the macromolecule lab?
In order to figure out what a positive test looks like if there was starch/protein/lipid present and what it looks like if there was not the macromolecule present
