Study Notes

Multiple Choice

Infectious diseases are caused by pathogens, while non-infectious diseases are not.
AIDS, Cholera, and Influenza are examples of infectious diseases.
Lung cancer is a non-infectious disease.
The image above depicts a bacterium.
The immune system destroys pathogens by engulfing them with macrophages.
Chickenpox is caused by a virus with an incubation period of approximately two weeks.
The best strategy for preventing tetanus infections is washing wounds with soap, as it is caused by a bacterium found in soil, dust, and manure.
A person approaching a plane mirror at 2 m/s approaches their image in the mirror at 4 m/s.
The speed of the person and their image is doubled.
The image formed by a plane mirror is virtual, upright, and laterally inverted.
A blurred image can be focused by moving the screen away from the lens and object OR by using a lens of shorter focal length.

Disease

Clostridium tetani, the bacterium that causes tetanus, multiplies anaerobically in deep tissue wounds.
Tetanolysin is the toxin produced by Clostridium tetani and causes tetanus.
Antibiotics like Metronidazole or Penicillin are recommended for treating tetanus.
The recommended antibiotic must be effective against the specific bacterial species involved.
Tetanus toxoid is a type of vaccine.
Vaccinations are effective in preventing tetanus.
An epidemiological study conducted in Sydney identified a trend of increasing emergency department visits related to traumatic brain injuries among 5-17 year-olds playing contact sports.

Optics

A ray diagram showing an observer viewing the image of an object O in a plane mirror should illustrate the object, the observer, the mirror, and the reflected rays forming the image.
When a convex lens forms an image, either a real or a virtual image can be formed.
The real image is formed on the other side of the lens from the object.
The virtual image is formed on the same side of the lens as the object.
Converging lenses converge light rays, while diverging lenses diverge light rays.
In a ray diagram for a convex lens, the focal point is the point where parallel rays of light converge.
The image formed by a convex lens can be magnified or diminished depending on the position of the object relative to the lens.
The eye's cornea and lens refract light to focus an image on the retina.
The retina contains photoreceptor cells, which convert light energy into electrical signals.
The optic nerve transmits these electrical signals to the brain.
The cornea is the transparent outer layer of the eye which refracts light.
The iris is the colored part of the eye which controls the amount of light entering the eye.
The lens is a transparent structure that focuses light.
The image formed by the eye is real, inverted, and diminished.
The image formed in a plane mirror is virtual and upright.
Myopia occurs when the eye is too long or the lens is too strong which means the image is formed in front of the retina.
Concave lenses are used to correct myopia.

Chemical Reactions II

Complete combustion occurs when there is sufficient oxygen.
Incomplete combustion occurs when there is insufficient oxygen.
CO2 is produced during complete combustion and causes global warming.
CO is produced during incomplete combustion and causes carbon monoxide poisoning.
Methane (CH4) and Ethane (C2H6) are examples of organic compounds, and burn with a blue flame in a Bunsen burner.
The Bunsen burner uses a fuel gas such as natural gas, propane, or butane.
The fuel gas burns with a yellow flame when there is insufficient air.
The fuel gas burns with a blue flame when there is sufficient air.
A pale blue flame is produced when the air hole is half open, while a pale blue flame with a distinct inner cone is produced when the air hole is fully open.
The pale blue flame with an inner cone is hotter than the former.

Electrical Circuits II

The potential difference across a resistor is measured in volts.
The unit for current is Amperes.
The resistance of a resistor is measured in Ohms.
The current flowing through a resistor is directly proportional to the potential difference across it.
Ohm’s Law is used to calculate the relationship between potential difference, current and resistance.
Energy is measured in Watts.
The power dissipated in a resistor is the rate at which electrical energy is converted into heat energy.
Power is calculated by multiplying the potential difference and the current.
In a series circuit, the current is the same at every point.
In a parallel circuit, the potential difference is the same across each component.
When resistors are connected in parallel, the total resistance is always less than the smallest individual resistance.
The combination of resistors can be used to create circuits with specific resistances.
The total power in a parallel circuit is equal to the sum of the powers dissipated in each branch of the circuit.
The same amount of current flows through each resistor in a series circuit.
The current flowing through each resistor in a parallel circuit is different.
The equivalent resistance of a series circuit is the sum of all the resistances in that circuit.
The equivalent resistance of a parallel circuit is the reciprocal of the sum of the reciprocals of the resistances of each branch of the circuit.
