both dominant and recessive alleles

A person's genotype is their genetic makeup and includes both dominant and recessive alleles. Phenotype is how the genes express themselves in physical characteristics.

Word Knowledge

Darren dreaded carpooling with the egotist Shelly, who talked about herself nonstop.

Self–important person.

Arithmetic Reasoning

The __________ is the greatest factor that divides two integers.

greatest common factor

The greatest common factor (GCF) is the greatest factor that divides two integers.

Mechanical Comprehension

The mechanical advantage of a wheel and axle is equal to the:

ratio of the diameters of the wheels

A wheel and axle uses two different diameter wheels mounted to a connecting axle. Force is applied to the larger wheel and large movements of this wheel result in small movements in the smaller wheel. Because a larger movement distance is being translated to a smaller distance, force is increased with a mechanical advantage equal to the ratio of the diameters of the wheels. An example of a wheel and axle is the steering wheel of a car.

Mechanical Comprehension

If A = 9 ft. and the green box weighs 30 lbs. what is the torque acting on the A side of this lever?

270 ft⋅lb

For a lever, torque is weight x distance from the fulcrum which, in this case, is: 30 ft. x 9 lbs. = 270 ft⋅lb

General Science

A large naturally occurring community of flora and fauna occupying a major habitat is:

a biome

A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).

General Science

The most diverse kindgom of life is which of the following?

protists

Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)

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.

Arithmetic Reasoning

What is c⁵ x 4c⁷?

4c¹²

To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:

c⁵ x 4c⁷
(1 x 4)c^{(5 + 7)}
4c¹²

Math Knowledge

Solve 3b + 2b = 9b - 9y + 8 for b in terms of y.

1\(\frac{5}{6}\)y - 1\(\frac{1}{3}\)

To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.

3b + 2y = 9b - 9y + 8
3b = 9b - 9y + 8 - 2y
3b - 9b = -9y + 8 - 2y
-6b = -11y + 8
b = \( \frac{-11y + 8}{-6} \)
b = \( \frac{-11y}{-6} \) + \( \frac{8}{-6} \)
b = 1\(\frac{5}{6}\)y - 1\(\frac{1}{3}\)
