16 Questions
What is the neutralization equation for acid and base?
Acid + Base -> Water + Salt
What are the basic units of carbohydrates, lipids, proteins, and nucleic acids?
Monosaccharides, fatty acids, amino acids, nucleotides
What are macronutrients and how many are necessary for humans?
Nutrients needed in large amounts; 3
How do nutrients move in our bodies through the process of osmosis?
From a higher concentration to a lower concentration
What is the difference between organic and inorganic compounds?
Organic compounds contain carbon and hydrogen, while inorganic compounds do not.
What are macronutrients and how many are necessary for humans?
Macronutrients are nutrients required in large amounts, and humans need 3 of them.
How do nutrients move in our bodies?
By active transport
How does the pH scale work? What does it tell us?
The pH scale measures the concentration of hydrogen ions in a solution. A lower pH indicates a higher concentration of hydrogen ions.
Which stage of the nitrogen cycle involves the conversion of ammonia or ammonium into nitrite and then into nitrate?
Nitrification
What is the primary process that converts atmospheric nitrogen (N2) into ammonia (NH3) or ammonium (NH4+), making it available for plants' use?
Fixation
Where does nitrogen assimilation occur in the nitrogen cycle?
When plants absorb dissolved nitrogen compounds from the soil
What is the main source of ammonia or ammonium for the nitrogen cycle?
Organic nitrogen from dead plants and animals
What is the role of Nitrosomonas and Nitrobacter in the nitrogen cycle?
Absorbing nitrates and converting them into organic nitrogen
Which process releases nitrogen gas into the atmosphere, making it available for fixation to start the cycle again?
Denitrification
How does the nitrogen cycle indirectly relate to the oxygen cycle?
Nitrogen supports photosynthesis, indirectly linking it to the oxygen cycle
What is the consequence of disrupting the processes of the nitrogen cycle?
Negative impacts on ecosystems, agriculture, and human health
This quiz covers the steps of the nitrogen fixation cycle and the definition of vocabulary related to environmental science. It also explores acids and bases, including examples, the pH scale, acid/base indicators, and neutralization equations.
