corruption
Essential baseness, depravity.
Automotive Information

Control arms connect a vehicle's suspension to the frame. The connection to the wheels is through:

ball joints

Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.

Word Knowledge
The words to the song are elusive, as the singer tends to mumble.

General Science

Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.

negative, positive

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

General Science

Cellular fermentation takes place:

anaerobically

If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.

Arithmetic Reasoning

Convert x-3 to remove the negative exponent.

\( \frac{1}{x^3} \)

To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.

Shop Information
combination wrench

This tool is a(n) __________.

combination wrench

Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.

Mechanical Comprehension

Lisa lifts a 25 pound box from the floor onto a loading dock 4 ft. off the ground. Sam slides the same box along a ramp to move it up another 4 ft. onto a flatbed truck. Who has done more work?

They have done an equal amount of work

Work is force multiplied by distance. Because both Connie and Sam moved the same weight the same distance they have done an equal amount of work. Sam employed the mechnacial advantage of an inclined plane so he exerted less effort to do the work but the amount of work done was still the same.

General Science

Which of the following represents the largest value?

1 ML

Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.

General Science

Which is the proper order of Earth's atmospheric layers from the surface up to space?

troposphere, stratosphere, mesosphere, thermosphere

The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
