The periodic table is arranged in increasing _______ number
Atomic
Biologist who came up with natural selection (environmental factors acting on a population)
Charles Darwin
What is a light year?
The distance light travels in a year (light year is a distance not a measurement of time)
The other 2 cycles studied apart from the water cycle
Carbon and nitrogen
How far something is in a straight line
Displacement
What are the three subatomic particles in an atom?
Proton, neutron and electron
Breeding particular organisms with desirable characteristics to pass on to the next generation
Artificial selection/ selective breeding
Type of nuclear reaction that produces energy in stars
Nuclear fusion
Names of the 3 spheres in the biosphere
Lithosphere, hydrosphere, atmosphere
Any of Newton's 3 laws
1. An object at rest will remain at rest unless acted upon by a force/ a object in motion will continue to move at the same speed and direction unless acted upon by a force.
2. F=ma (Force is equal to the change in momentum per change in time/ for a constant mass, force = mass x acceleration).
3. For every action there is an equal and opposite reaction force.
Metal that is liquid at room temperature
Mercury Hg
In related species, characteristics that have the same basic structure e.g. human hand, whale flipper and bat wings (pentadactyl limb)
Homologous structures
White dwarf
Equation of photosynthesis
Carbon dioxide + Water ---> Glucose + Oxygen
Energy may be transferred from one object to another, but is never created or destroyed
Law of conservation of energy
Name for the last group (most right column) (not accepting group 8/18)
Noble/inert gases
The species AND location that Darwin observed to propose evolution by natural selection
Darwin's finches on Galapogas islands
The change in frequency of sound noticed when a fast loud object moves past an observer
Doppler effect
What is the cause of different seasons
Orientation of the Earth/ Earth's tilt and orbit
Formula for speed and calculate my speed if i travel 26km in 15mins
Distance/time = 26km/0.25h = 104km/h
Number of neutrons of Uranium
232-92 = 140
Pieces of evidence that support evolution (at least 3 of 5 to be correct)
fossils, comparative anatomy, DNA & protein sequencing, distribution of species and embryology
Describe two pieces of evidence that support the Big Bang Theory
Red shift and the cosmic microwave background radiation
Information scientists can gather about past conditions from ice cores
Composition of the air / temperature
