The carbon source of cellular respiration is carbohydrates in living organisms. The carbon sink of cellular respiration is CO2 in the atmosphere. What is the carbon source for photosynthesis?
Carbon dioxide in the atmosphere.
Ocean Acidification
Increase in carbon dioxide levels in aquatic environments resulting in increased acidity.
Carbon Footprint
Measure of greenhouse gases emitted from daily activities.
Polar Covalent Bond
A bond where the electrons are not shared equally.
Wetlands
An area which is home to standing water for notable parts of the year.
Which greenhouse gas can spend most of its time in the atmosphere?
Perfluorocarbons.
Slash-and-Burn Agriculture
Farming method that removes land in a place of food.
Measure of how much heat is trapped in the atmosphere from greenhouse gases.
Precipitation
Water that falls from the clouds in the atmosphere in the form of ice or liquid.
How does an atom becomes positively charged. How does it become negatively charged?
It becomes positively charged when it loses one or more electrons and therefore has more positive protons than negative electrons.
It becomes negatively charged when it gains one or more electrons and therefore has more negative electrons than positive protons.
(THINK OPPOSITE)
What impact does climate change have on land ice, runoff, and sea ice?
Climate change is making the ice melt into water and then the water is raising sea levels and or flooding will occur. Artic animals face lack of food and lack of a place to habitat.
Primary Producers
Organisms that fix atmospheric CO2 into organic carbon.
Industrialized Agriculture
Modern farming involved in producing food at the industrial level.
Surface Tension
The attraction of water molecules to each other that causes the surface of water to overfill a glass or form a droplet.
What is the main characteristic of lipid molecules?
They are hydrophobic, meaning they repel water.
Chloroplast
Site of photosynthesis.
Desalination
Removal of salt from seawater to produce drinkable water.
Define fertility rate. What does the fertility rate have to be to hold the population count steady? Explain why it is this number.
How many kids a person has is their fertility rate. 2.1 is the rate that fertility would need to be to remain steady. This is because it would cancel out mom and dad and make up for still births or infertility.
Tributaries
The streams and small rivers that join up to form a larger river.
List the hierarchy of organization beginning from the smallest and building up.
Atom - Molecule - Organelles - Cell - Organisms - Population - Community - Ecosystem
Cellular Respiration
Conversion of sugar to carbon dioxide, water, and ATP.
Equilibrium
Physical balance in opposite forces.
Hydrologic Cycle
The cycle that involves two major forces: heat energy from the sun that causes liquid water to change to water vapor and the gravitational pull of the Earth that brings water to the surface.
Water Table
The boundary between saturated and unsaturated ground.
List the three sources of energy that are classified as fossil fuels.
Coal, Oil, Natural Gas.
