Chemistry
Which change of matter forms a new substance?
Chemical change
Is a body of water healthy if it has a high or low turbidity?
What is a low turbidity.
Describe where, how, and the age of the crust at the boundary and further away.
What is at divergent boundaries in the ocean. Magma rises and forms new crust at the break in the boundary. The newest crust is at the fault and the oldest is farther away.
How do producers get glucose?
How do consumers get glucose?
bonus: what is the glucose used for?
Explain the difference between a biotic and abiotic factor within an ecosystem. Give an example of each
Biotic is living and abiotic is nonliving
Biotic: Plants and Animals
Abiotic: Rocks, Water
Which group does not bond with other elements because it has a full shell of valence electrons
Group 18, Noble gasses
How does temperature impact dissolved oxygen
When temperature increases, dissolved oxygen decrease.
Bonus 10- explain why
What are two ways paleontologist can find the age of fossil or rock?
What are absolute and relative dating
Explain the difference between a pandemic and an epidemic
Pandemic is widespread, epidemic is localized
What could the result of a consumer in a food web only having one source of food
If that food source becomes less or extinct that could negatively impact the species that feeds on it as it will have fewer or no alternatives
Give an example of a homogenous mixture and a heterogenous mixture
Answers may vary but homogenous is the same throughout (Milk) and heterogenous has distinct parts (salad)
What is the ocean/estuaries accounts for 97% of all water on Earth, Fresh water account for 3 %. Most freshwater is frozen in icecaps and glaciers, groundwater has the 2nd most amount of fresh water, and then surface water sources such as lakes, rivers, swamps,
Which type of rocks are fossils found in?
Why?
Sedimentary
Better at preserving organic matter due to the heat not destroying the fossils
What do viruses need in order to reproduce?
A host
Give two examples of a limiting factor
Sunlight, water, nutrients, space
What does the law of conservation of mass state?
Use shapes to represent a balanced chemical equation.
Describe the difference between point source and non point source pollution. Give an example of each.
Point Source Pollution can be identified easily and non point source pollution can not.
Point Source: Someone littering
NonPoint: Runoff from fertilizer from multiple farms
What does the law of superposition state. Is this relative dating or absolute dating?
What is younger fossils are found above older fossils in rock and sediment, relative dating
What is good hand hygiene, staying away from sick people, keeping areas/body clean...some bacteria but mostly viruses are prevented with vaccines.
To treat viruses one must allow the virus to run its course and rely on the immune system to defeat the virus. Most bacterial diseases have a specific antibiotic to treat the infection.
Give an example of an adaptation and how it could be both advantageous and disadvantageous in different habitats
Example: White fur coat in winter but if it doesn't snow the white fur coat makes it stand out and more vulnerable to predators
Describe each subatomic particle that makes up an atom.
Include: name, charge, location, mass
word bank: nucleus, electron, proton, neutron, positive, negative, no charge, 1 amu, 1/1840 amu, orbit, electron shell
What is protons are positive and are found in the nucleus mass of 1 amu, neutrons are found inside the nucleus with no charge and 1 amu, and electrons orbit the nucleus with a very small amu 1/1840 amu.
What causes algal bloom in a water system?
What can be a result of algal bloom?
What is an over abundance of nitrogen
The abundance of nutrients feed microscopic algae that steal the nutrients, block out sunlight, and once they die cause a severe lack of oxygen and a lot of turbidity.
What are the criterion for index fossils, and how do paleontologist use index fossils?
What is index fossils must be geographically widespread, lived for a relatively short amount of time, and be easily recognized. Index fossils are used to find the relative age of surrounding fossils/rock layers
Describes vectors and provide 2 examples
What is vectors are organisms that transmit diseases/parasites when biting a host. Examples: ticks and mosquitos
Describe the three symbiotic relationships.
Bonus: provide one example of each
