Unit 1
Give an example of a qualitative observation about this room and an example of a quantitative observation
answers vary
These are the two types of population growth
logistic and exponential
Why is water considered to be polar?
because of the unequal electron sharing in the covalent bonds of oxygen and hydrogen
This type of transport involves channels called aquaporins and is a type of facilitated diffusion of only water molecules
osmosis

Tuck
Give an example of a variable that would be controlled if we were testing how the amount of water influences plant growth
soil type
sunlight
nutrients
plant species
This is the pattern of population distribution likely seen with plants that have seeds dispersed by the wind
random distribution
What property of water explains that water molecules stick to each other
cohesion
What is the name of the model we use to describe the cell membrane?
fluid mosaic model
These organisms create their own energy from the sun
Autotrophs
On a graph, what variable typically goes on the x-axis?
the independent variable
the carrying capacity
What does an enzyme do?
speed up rate of reaction by lowering the activation energy
When molecules move naturally from areas of high concentration to low concentration are they moving WITH or AGAINST their concentration gradient?
with
What is the role of a buffer?
to resist change in pH of a solution
What characteristic of life is demonstrated in this example: When you touch a hot skillet, you pull your hand away
Response to Stimuli
Draw the graph showing logistic growth and label all three stages
stage 1- rapid growth
stage 2- growth has slowed
stage 3- growth slows and stays near carrying capacity
This type of reaction involves adding water to a polymer, thus breaking it into its monomer components.
Hydrolysis Reaction
This organelle maintains the cell shape with long protein fibers
cytoskeleton
What do we call the signaling molecule?
Ligand
