a. Ice caps
What does ppm stand for
Parts-per-million
What is the SI unit for force
Newton or (N)
What is an independent variable
A variable that isn't changed at all by the experiment
What produces more energy nuclear fusion or nuclear fission
Nuclear fusion
How do pesticides and runoff affect nearby rivers and lakes
the pesticides wash into the water ways, polluting them and killing fish
If a car goes 200 miles in 3 and 1/2 hours, what is its speed in mph
rounded to nearest tenth
57.1 mph
What are Mendelian Genetics used for
The inheritance patterns of single gene diseases
What are control groups used for
In experiments
How does the sun produce energy
Nuclear fusion
How will air pollution affect the food industry
Air pollution can directly contaminate the surface of bodies of water and soil. This can kill crops or reduce their yield
What is the formula for velocity
V=d/t where V is velocity, d is displacement, and t is time
Which Newton's law of motion was applied to the invention of seat belts.
Newton's 1st law
Determine the independent and Dependent variable:
John wants to determine the effect of a sterilizer on the growth of his grass.
IV: Amount of sterilizer DV: Growth of grass
What is a simple definition of artificial intelligence
Artificial intelligence (AI) makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks
Why do pesticides cause health affects to humans
Because of their acute toxic affects by their corrosive and irritant properties
If a see saw lever has a mechanical advantage of 1, where must the fulcrum be
The fulcrum must be exactly in the middle, so that moving one end will lift the other end by 1 meter
What is one of the 3 Mendelian genetics
The Law of Dominance and Uniformity, the Law of Segregation or the Law of Independent Assortment.
Is Amount of sunlight in a tree growing experiment an independent or dependent variable
Independent
What is CRISPR how will it change the future
CRISPR is a technology that research scientists use to selectively modify the DNA of living organisms. In the future this will be able to be used to prevent human babies from getting certain diseases and even change the way they look.
How do greenhouse gases contribute to global warming
they absorb the sun's heat that radiates from the Earth's surface, trap it in the atmosphere and prevent it from escaping into space
What is a mole ratio
The ratio between the amounts in moles of any 2 compounds involved in a balanced chemical equation.
Describe Isaac newtons 1st law of motion
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force
