Q

Theory of evolution

A

Charles Darwin. Living things can change.

All vertebrates use same set of parts to build body.

All sexually reproducing organisms start as one cell. Common origin

All aerobic organisms use oxygen to get energy via respiration. Even use same enzymes

Lower rock layers are older. Fossils become fewer and simpler

Q

Atomic theory

A

All matter is made up of tiny indivisible particles called atoms.
Smallest object that retains properties of element.
Atoms are composed of electrons and nucleus
The nucleus contains protons and neutrons
Can it be created or destroyed

16
Q

Ion

A

an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. If an element has two electrons in outer shell it loses it to become 2+ ion

17
Q

Isotope

A

Isotopes are atoms with the same number of protons but a different number of neutrons. Can be unstable/radioactive

18
Q

period

A

Horizontal row on the periodic table. 7 periods. Amount of electron shells. Top has one going down to 7.

19
Q

group

A

Vertical row on the periodic table. They have similar chemical behaviour. Number of electrons in outer shell.

20
Q

Factors affecting rate of reaction

A

Temperature
Pressure
Concentration
Catalyst: a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

21
Q

Newtons laws + application to life

A

1) An object at rest will remain at rest and an object in 1) 1) motion will remain in motion unless acted upon by an external, unbalanced force.
2) F=ma
3) For every action there is an equal and opposite reaction

22
Q

life cycle of star

A

star nebula: average star-red giant- nebula- white dwarf

star nebula: massive star- red supergiant- supernova-neutron star or black hole

23
Q

formation of a star

A

1) clouds of dust and gas are disturbed by the gravity of a nearby phenomina
2) clumps of hydrogen form
3) enough hydrogen causes it to heat up and the gas fuses producing helium and energy. ignites

24
Q

Galaxy

A

a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.

25
Q

stars

A

A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.

26
Q

nebulae

A

A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases.

27
Q

apparent magnitude

A

Apparent magnitude is a measure of the brightness of a star or other astronomical object as seen from the Earth’s location.

28
Q

absolute magnitude

A

An object’s absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10.0 parsecs (32.6 light-years), without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust.

29
Q

Ohm’s Law

A

V=IR

voltage=current x resistance

30
Q

Aim

A

The aim was to conduct an experiment investigating music genres effect on an individual’s visual reaction speed. These genres include rap/hip hop, heavy metal, pop, classical

31
Q

Hypothesis

A

The hypothesis was that the genre of music classical will lead to the quickest reaction time. Pop will induce the second quickest reaction followed by rap/hip hop and then heavy metal

32
Q

conclusion

A

The aim was to conduct an investigation to discover how different genres of music, affect an individual’s visual reaction speed. The hypothesis stated that classical music would translate to quickest reaction speed. This would be followed by Pop with rap/hip hop and heavy metal with the slowest rate of reaction time overall. It was concluded that heavy metal improved reaction speed from the control and translated to the quickest time overall. This was followed by Rap/Hip hop, classical and lastly pop. Therefore, the hypothesis was rejected.

33
Q

Risks

A

glass cuts from smashed computer screen

damage to ear from loud music. tennitus or rupturing of eardrum

ability to carry out test due to offensive language

34
Q

control

A

reaction time test without music

35
Q

Indipendant variable

A

genre of music being played (with this comes different Tempos, tones and pitch. etc.)

36
Q

Dependant variable

A

Reaction speed of individual in milliseconds

37
Q

controlled variable

A

Volume of music, time listening to music, reaction time test used, computer used (different computers may have different reaction speeds), Randomness of music order to minimise the effects of common variables.

38
Q

Nucleotide

A

Made from sugar phosphate and nitrogen

3 makes 1 amino acid

39
Q

DNA format

A

Adenine
