271 Multiple choice questions
Term 1 of 271
What type of exercise are slow twitch muscles designed for?
Physical fitness
Aerobic exercise
Aerobic respiration
Resistance exercise
Term 2 of 271
Describe the function of the chloroplasts
Site of photosynthesis as they contain chlorophyll
Stores genetic material for the cell
Involved in protein synthesis
Responsible for cellular respiration
Term 3 of 271
What type of control is exhibited in cardiac muscle?
Hypnosis
Voluntary movement
Striations
Involuntary control
,Term 4 of 271
What are the two parts of a longitudinal wave.
The particles are displaced in the same direction that the wave travels.
Moles = mass ÷ relative atomic mass (molar mass)
Acetylcholine (a neurotransmitter)
Compression (squashed)
Rarefaction (spread out)
Term 5 of 271
What does EEG stand for?
Electromyelogram
Negative
Electroenchephalogram
It Shortens
Term 6 of 271
Describe the function of the nucleolus
Site of photosynthesis as they contain chlorophyll
Multi-lobed nucleus
enzymes found within the lysosomes
Provides rigidity and protection to the cell
Produces ribosomes and RNA
,Term 7 of 271
State the two factors that affect the strength of metallic bonding
A thick insulating layer around the axon
Site of photosynthesis as they contain chlorophyll
Size of ion
Charge on ion
Melting point increases Down the group
Term 8 of 271
Explain the trend in atomic radius across a period
When the neurone is not transmitting an action potential. During this time the K+/Na+ pump
is at work
Melting point increases across the metals and then decreases throughout the non-metals
Greater nuclear charge (more protons)
Same number of electron shells
Same amount of electron shielding
Allows for more oxygen to be carried in the cell
Term 9 of 271
How fast do electromagnetic waves travel in a vacuum?
To push through the protective layer of the egg cell
In a transverse wave the displacement is at right angles to the direction of the wave travel.
All electromagnetic waves travel at the same speed in a vacuum. 3 x 10^8
Stores water and chemicals for cell use. Also maintains turgor of cell
, Term 10 of 271
What is Refractive Index?
The ratio of speed of light in a vacuum to its speed of light in the medium.
Wave motions that store energy rather than transferring energy to other locations.
A measure of how well an atom attracts a bonding pair of electrons in a covalent bond
When a more reactive element takes the place of a less reactive element in a molecule
Term 11 of 271
Explain the trend in atomic radius down any group
Higher energy levels are filled. The orbitals in higher energy levels are further from the
nucleus
Atoms gain protons as you go down a group
The atomic radius remains constant down a group
Atoms lose electrons as you go down a group
Term 12 of 271
Define the term oxidation
A reaction involving elemental oxygen is a redox reaction
Oxidation is the process of forming new compounds
Oxidation is the decrease in oxidation state
Oxidation is loss of electrons
