Chemicals in the Environment
This process involves certain plants and bacteria converting N2 into other N-containing compounds so they can be used by organisms.
Nitrogen fixation
0-6.9
These are nutrients we need large amounts of
Macronutrients
The process plants use to uptake water into their roots
Osmosis
This refers to living things that tell us about the quality of a sample of water
Biological indicators
Nitrogen, Phosphorus, and Potassium
Neutralization reactions produce these 2 compounds as products
salts and water
Carbon
The substrate of mold growing on a slice of bread is
The bread
You would generally tend to see biodiversity in a water source increase when oxygen (increases/decreases)
Increases
This is a type of pesticide that targets plant pests.
Herbicide
This process of acid rain neutralization involves the use of calcium carbonate being reacted with emissions at the point-source of pollution (ie. the factory)
Scrubbing
This organic molecule is used for short-term energy use
carbohydrates
This process breaks down large molecules we eat into smaller ones using water
Hydrolysis
Find the ppm when there is 15mL of solute added to 900mL of a solution.
16666.6ppm
This is one of the pollutant compounds that is released by combustion reactions (car exhaust, fossil fuel heating, etc)
sulfur dioxide, nitrogen oxides, carbon dioxide
What are 2 properties of bases?
Slippery/soapy, bitter, pH of more than 7, react with metals
Proteins are made up of combinations of different types of this unit
Amino acids
This form of passive transport is used to move nutrients from an area of high to low concentration
Diffusion
Describe LD50
The dose of a substance that is lethal to 50% of a population
This chemical compound is also referred to as "sour gas"
Hydrogen sulfide
Describe how catalytic converters on cars help reduce emissions into the atmosphere.
They contain previous metals that react with chemicals in exhaust to neutralize them before they reach the atmosphere.
Biuret solution is used to test for this molecule
Protein
In this process of nutrient uptake, cells expend energy to move nutrients from an area of low concentration to an area of high concentration.
Active transport
A lake next to a farm has a large algae bloom. What is a reason this could have happened? (be specific!)
Nitrogen or Phosphorus runoff
