Population
What are the 2 types of population growth patterns?
Exponential and Logistic
What allows water to have amazing properties?
Hydrogen Bonds
What part of the water molecule is negative?
Oxygen
liquid to gas
Evaporation
Who is our current principal?
Ms. Clark
Define population
a group of organisms of the same species in the same place at the same time
Why is water polar?
electrons are not shared evenly within the covalent bonds of water, resulting in positive and negative regions
When water molecules are further apart what state is water in?
Solid State
What is the driving force behind the water cycle
the sun
What street is Mt. Hebron on?
Old Fredrick Rd
If the population's growth rate is 0.02, what is happening to the size of the population?
The population is increasing
Surface tension is an example of?
Cohesion
When water is the solvent, what is the solution called?
Aqueous
Evaporation of water from the stomata of plants
Transpiration
When did Mt. Hebron open
1965
Explain why most populations grows in an S shape curve?
Initially population grows rapidly because there is a great availability of resources. Then the population growth slows down eventually reaching its carrying capacity due to a limiting factor.
water molecules are not attracted to the oil molecules because they have no charge
Why is it harder to pick up a glass slide cover in water compared to a glass slide covered in alcohol.
Adhesion, water sticks to other surfaces
What process can wash pollutants into the rivers
runoff
Name a current chemistry teacher
Ms. Sankey or Ms. Lu
What is the logistic growth equation and what do the variables represent?
rmaxN (K-N/K)
rmax - growth rate
N - initial population
K - carrying capacity
What are the 3 categories substances that are water soluble?
ionic compounds, polar compounds, some proteins
Which 2 properties of water allows us to maintain homeostasis?
High Specific Heat and Cooling Agent
Water cycle is a closed system what does that mean?
no water enters from beyond the system nor leaves the system
Which team won the state championship every year between 1992 and 2007 except 1996?
Girls Lacrosse
