Definitions Part 1
What is the increased concentration of a material as it moves up the food chain?
Biomagnification
Organic and Inorganic
Made by or comes from something that was living
Comes from nonliving sources
What is the Role of a lipid (Fats) ?
storage of unused chemical energy
What measures the amount of free hydrogen and hydroxide ions in the water?
PH
The unusable remains or byproducts of something is called what?
What is waste
What is the main source of fuel for energy in the human body?
Carbohydrate
Acid / Base
What has particles that create an element called hydrogen
What has particles that create hydroxide
Minerals you need a lot of are called what?
Macrominerals
What is it called when you mix and acid and a base together?
Neutralization
What is the difference between persistent and non persistent waste?
persistent waste is a long-lasting environmental contaminant, whereas non-persistent waste is easily degraded
What builds up and repairs muscles and other tissues?
Protein
Dispersion and Deposition
Pollution gets spread around by diffusion and wind.
Pollutants in the air are spread to the ground by precipitation
What is an important constituent of Blood?
Iron
What is one example of how humans offset the effects of acid rain
Liming, Scrubbers, Catalytic Converters
What is it called when some gases in the atmosphere trap heat which keeps the Earth at a specific temperature that allows for life?
Greenhouse effect
Taking in substances through eating or drinking is called what?
Ingestion
Groundwater pollution
Dangerous chemicals find their way into the water that fills the space underground. Due to a relatively low flow rate this can lead to high concentrations of pollutants.
How do humans absorb nutrients?
Digestive tract
Respiratory tract (after inhalation)
Skin
An antacid tablet is a mild base that reacts with the acid in your stomach to form compounds that are less upsetting to your stomach. What is this an example of?
Neutralization Reaction
What is the Paris Agreement ?
The Paris Agreement is an international treaty that aims to reduce greenhouse gas emissions and limit global warming
What is it called when chemicals get further from their source and become less concentrated?
Dilution
Surface Water Pollutants
Chemicals that find their way into rivers, lakes and oceans. Most often these chemicals are diluted because water flows and pollutants are spread out. What is this known as
What are the two minerals essential to maintenance of bones?
Calcium
Phosphorus
What is the difference in strength between one level on the PH scale Example the difference between 3 and 4?
10 times stronger or weaker
