Carbon
What is element that is fundamental to all life
100
Molecule with a positive and negative charged end has polarity.
What is polar molecule?
100
one hydrogen and two oxygen
What is the properties water has because it is a polar molecule.
100
Raised boiling point, decreased freezing temperate, and ability to create osmotic pressure. Fresh water does have these properties.
What are the colligative properties of seawater and does fresh water have these properties?
100
It forms layers and dense water is heavy and sink below less dense layers.
What is how and why is the ocean stratified by density?
200
The process of elements and compounds moving and forming organisms on Earth.
What is biogeochemical cycle.
200
The process of a cell moving materials from low concentration to high concentration.
What is is active transport.
200
Ice is less dense than water. Surface ice insulates the water below from further cooling.
What is why does ice float and how is this important to thermal conditions?
200
The amount of acid in the water. The deeper you go in water the lower the PH.
What is the factor that affect seawater's PH and why does PH change with depth?
200
They can maintain a core temperature.
What is advantage of being an endotherm?
300
CO2 is created by burning fossil fuels because carbon is part of all plants and animals.
What is the role of carbon in organisms.
300
The process of moving substances in or out of a cell by normal diffusion.
What is passive transport?
300
homogenous and hetergeneous
What is two kinds of mixtures?
300
Chloride sodium, sulfate, magnesium, bicarbonate, calcium, and potassium.
What are the most abundant chemical in seawater besides hydrogen and oxygen?
300
Scattering occurs initially when light reaches the waters surface, the water molecules absorb the energy.
What is how does water scatter and absorb light?
400
Organisms require nitrogen for organic compounds such as protein, chlorophyl, and acids.
What is the role of nitrogen in organisms.
400
Diffusion and osmosis regulate the salt intake and excretion in all marine animals, birds, and reptiles.
How can diffusion and osmosis affect marine organisms?
400
the state in which the molecules of a solute are evenly dispersed with the molecules of a solvent.
What is a solution?
400
Sea salts come from rain, runoff, erosion, and other natural forces. No the ocean is not becoming more salty.
What is where do sea salts come from? Is the ocean getting salter?
400
The weight of the water column above a given depth.
What is hydrostatic pressure?
500
Most sand is made of silica because it is a common component of rocks and minerals and does not break down easily.
What is the role of silicon in marine organisms.
500
The total quantity/concentration of all dissolved inorganic salts, brackish water.
What is salinity and the major sea salts?
500
Waves tides and currents mix waters of varying salinity to make them more uniform.
What is how does temperature and salinity affect seawater density?
500
Temperature dictates the rate of chemical reaction. The higher the temp. the more quickly the reactions take place.
What is how does temperature affect metabolism?
