Forces
A force that slows the movement of a sliding object.
What is friction?
An atom that is charged because it has gained or lost an electron
What is an ion?
The shape of DNA
What is a double helix?
Cycling of carbon between the atmosphere, biosphere, hydrosphere, and lithosphere
What is the carbon cycle?
This must be measurable, contain what you will be changing and what you will be measuring, be specific and have a question mark
What is a research question?
A type of friction that slows objects as they move through the air.
What is air resistance?
Ionic bonds are formed this way.
What is transferring electrons?
Adenine and thymine, cytosine and guanine
What is the base pairing rule?
A metal saucepan handle gets hot when placed on a hot plate
What is conduction?
The manipulated variable.
What is the independent variable?
A force that is transmitted through a cable, rope, wire or string when it is pulled tight by forces acting from opposite ends.
What is tension?
In an ionic bond, these elements are likely to gain electrons
What are non-metals?
Made up of a sugar, a phosphate and a base
What is a nucleotide?
The ‘trapping’ of some of the Earth’s infrared radiation in the atmosphere
What is the greenhouse effect?
Anything that can change or be changed
What is a variable?
A force that attracts any two objects with mass.
What is gravitational force?
The type of ion that is formed by the loss of one or more electrons
What is a cation?
The process of making a complementary mRNA copy of the DNA
What is transcription?
These carry impulses from the central nervous system to muscles and glands
What are motor neurons?
This is an experimental group that is purposefully added in experiments to be a comparison to the experimental group
What is a control group?
A force that the ground (or any surface) pushes back up with.
What is normal?
All atoms want is a full valence shell.
What is the octet rule?
Always masked in the heterozygote.
What is a recessive allele?
These are stored in the axon terminals of presynaptic neurons and are released into the synaptic gap.
What are neurotransmitters?
A measure of how close data points or measurements are to one another
What is precision?
