Water
What does it mean that water is a good solvent?
water can dissolve just about anything
Is water a carbon compound?
No! There is no carbon in a water molecule (just H2O)
What is an abiotic factor?
a non-living variable that can affect a habitat
What are the names of the three ocean zones?
Sunlight zone, Twilight zone, and Dark zone
Define the word element.
It's the simplest form of matter.
Is water an atom, an element, or a compound?
compound
The building blocks of nucleic acids are called...
nucleotides
True or False: Extreme temperatures can limit the amount and kinds of living things in a habitat.
True!
Describe some creatures that can be found in the twilight zone.
Goblin sharks, lantern fish, anglerfish, very few (if any) plants, and other unusual looking creatures that might make their own light.
What are the two parts of a chemical reaction?
the reactants and the products
What percentage of water on the surface of the earth is freshwater?
less than 1%
These carbon compounds are good for long term storage of energy and made by cells
lipids
Does the amount of oxygen in the air increase or decrease as you move away from sea level (increase altitude)?
Oxygen decreases as altitude increases
Describe the temperature, pressure, amount of sunlight, and depth of the SUNLIGHT zone
the sunlight zone is from 0m-200m below the surface, it has the greatest amount of sunlight, the water temperature ranges from 0°C to 25°C, and it has the least amount of pressure.
What are the three most abundant elements in living things?
C (carbon), H (hydrogen), and O (oxygen)
This property of water means that it takes a lot of energy to raise the temperature of 1 mL of water by 1°C
high specific heat
The building blocks of these compounds are amino acids
proteins
What is the difference between a soil and a sediment?
Soils are made up of decaying plants and animals found on land habitats and small rock particles, and sediments are decaying plants and animals from aquatic habitats and small rock particles.
Sediments are submerged soils and can be transported by water.
Describe the temperature, pressure, amount of sunlight, and depth of the TWILIGHT zone
The twilight zone is 200m-1000m below the surface, there is very faint light, the pressure is medium-high, and the temperature of the water is between 20°C and 4°C.
What's the difference between a compound and a molecule?
a compound is two or more atoms from different elements joined together chemically, and a molecule is two or more atoms from the same or different elements joined together chemically.
In °C, what is the freezing point and the boiling point of water?
freezing point is 0°C, boiling point is 100°C
What are the two types of carbohydrates? Give an example of each.
Sugars (simple carbs, such as candies, syrups, natural fruit sugars) and
Starches (complex carbs, such as pasta, rice, potatoes)
List the six abiotic factors that can affect land and/or freshwater habitats.
Temperature, Precipitation, Sunlight, (Dissolved) Oxygen, Type of Soil (Sediment), and Other Chemicals
Describe the temperature, pressure, amount of sunlight, and depth of the DARK zone
The dark zone is 1,000m-10,000m below the surface, there is NO light, the pressure is super high, and the water temp is 4°C.
How does chemistry relate to biology?
chemistry is necessary to understand atoms, elements, molecules, and compounds, which are found in all living things
