1

Blood pressure is generally highest in which of the following?

60% Answer Correctly

veins

arteries

heart

capillaries


Solution

Arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood.


2

Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:

58% Answer Correctly

1 m/s to a mass of 1 kg

1 mph to a mass of 1 kg

1 m/s2 to a mass of 1 kg/s2

1 m/s2 to a mass of 1 kg


Solution

Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.


3

Which of the following is not a characteristic of the Sun?

52% Answer Correctly

is composed of hydrogen and helium

makes up over 99% of the mass of the solar system

formed 2.6 billion years ago

is a yellow dwarf star


Solution

The Sun is a G-type main-sequence star (G2V) but is informally known as a yellow dwarf star. Composed of 73% hydrogen and 25% helium, the hot plasma that makes up the Sun reaches 9,900°F (5,505°C) at the surface. It formed approximately 4.6 billion years ago and makes up 99.86% of the mass in the solar system.


4

Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following? 

66% Answer Correctly

conduction

reflection

convection

radiation


Solution

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.


5

Which of the following members of the food chain are most alike?

65% Answer Correctly

producers and tertiary consumers

herbivores and autotrophs

scavengers and decomposers

primary consumers and omnivores


Solution

Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
