S


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.


2

A dominant trait will be expressed when paired with:

75% Answer Correctly

a gene

a dominant trait

a recessive trait

a chromosome


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.


3

Which of the following temperatures is least like the others?

43% Answer Correctly

32°F

0K

absolute zero

-273°C


Solution

Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.


4

This skeletal system is common in arthropods like insects, spiders, and crustaceans.

81% Answer Correctly

vertebrate

bone

exoskeleton

endoskeleton


Solution

An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.


5

Traits represented by genes may be which of the following?

82% Answer Correctly

all of these

recessive

expressed

dominant


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.
