What is the name of a cylindrical instrument useful for measuring small volumes of liquids?
graduated cylinder
200
Which biome is characterized by the following plants and animals? spruce and fir trees, moose, beaver, wolverines, and lynx
boreal forest (taiga)
200
What are two functions of lipids?
store energy, act as hormones, components of cell membranes
200
Photosynthesis converts ___________ energy to ___________ energy.
light, chemical
200
In what (specific) phase of the cell cycle do cells replicate their DNA?
S
300
What is the difference between an independent and dependent variable?
independent variable is something the experimenter changes on purpose, dependent variable is something that changes in response to the independent variable
300
Using one of the two examples we learned about in class (sharks or sea otters), describe how removing just one species can destroy an entire ecosystem.
sea otters killed for fur-> in the absence of predators sea urchin population explodes -> sea urchins eat up all the sea kelp -> sea kelp demolished and entire ecosystem disappears sharks removed (for shark fin soup) -> larger fish species normally eaten by sharks population explodes -> they eat all or most of smaller fish species -> now larger fish species die because they have nothing to eat
300
What organelle produces proteins?
ribosomes
300
Which enzyme helps convert ADP to ATP?
ATP synthase
300
What are two things mitosis is used for?
healing/replacing damaged cells, growth, asexual reproduction
400
What is the difference between a theory and a law?
theory is an explanation of an occurrence supported by many observations and experiments over time (why), a law describes relationships under certain conditions in nature (what)
400
What are the three types of symbiotic relationships we learned about? Use + (helped), - (hurt) and 0 (neutral) signs to show what is happening to the organisms in these relationships.
mutualism + + parasitism + - commensalism + 0
400
What are 3 molecules found in cell membranes?
proteins, phospholipids, cholesterol
400
Where is the most ATP produced during respiration?
electron transport chain
400
What is the last step of the cell cycle called, which is the division of cytoplasm?
cytokinesis
500
Name 4 of the 7 characteristics of life.
-made of one or more cells -maintain homeostasis -display organization -require energy -grow and develop -respond to stimuli -reproduce
500
What is the difference between exponential and logistic population growth?
exponential occurs when there are no limiting factors, logistic occurs when there are limiting factors
500
What is passive transport?
the movement of substances through the cell membrane without the use of energy
500
What process do both types of anaerobic respiration always occur after?
glycolysis
500
Explain how a cell becomes cancerous.
exposure to certain substances (tobacco, UV rays, chemicals, etc.) or a genetic predisposition causes mutations in a cell's DNA causing it to bypass the normal controls in the cell cycle and grow and divide uncontrollably
