Tertiary consumers eat which of the following?

59% Answer Correctly

primary and secondary consumers

decomposers

all of these

producers


Solution

Tertiary consumers eat primary consumers and secondary consumers and are typically carnivorous predators. Tertiary consumers may also be omnivores. Examples include wolves, sharks, and human beings.


2

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

52% Answer Correctly

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

is a yellow dwarf star

is composed of hydrogen and helium

formed 2.6 billion years ago


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.

50°F is how many °C?

72% Answer Correctly

58

122

-10

10


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


4

In a eukaryotic cell, which organelles deal with proteins?

63% Answer Correctly

all of these deal with proteins

ribosomes

endoplasmic reticulum

Golgi apparatus


Solution

The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles. Ribosomes produce proteins, endoplasmic reticulum helps synthesize proteins and fats, and Golgi apparatus prepares proteins for use.


5

When light travels between two substances it bends. This is called:

74% Answer Correctly

conduction

refraction

convection

reflection


Solution

Because different materials have different refractive indices, light changes speed when passing from one material to another. This causes the light to bend (refraction) at an angle that depends on the change in refractive index between the materials. The greater the difference, the higher the angle of refraction.
