The large intestine does which of the following?

82% Answer Correctly

breaks down proteins

processes the physical waste produced by digestion

breaks down starches

breaks down fats


Solution

The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.


2

Blood pressure is generally highest in which of the following?

61% Answer Correctly

arteries

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.


3

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

52% Answer Correctly

is composed of hydrogen and helium

formed 2.6 billion years ago

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

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

Which of the following states of matter exists at the highest temperature?

68% Answer Correctly

gas

none of these

liquid

solid


Solution

Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.


5

Traits represented by genes may be which of the following?

82% Answer Correctly

all of these

recessive

dominant

expressed


Solution

The traits represented by genes are inherited independently of each other  (one from the male and one from the female gamete) and a trait can be dominant or recessive.  A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
