1

An endoskeleton (internal skeleton) is a charateristic of __________ animals, including humans.

85% Answer Correctly

sentient

arthropod

vertebrate

spiny
Solution

An endoskeleton (internal skeleton) is a charateristic of vertebrate animals, including humans.

2

A dominant trait will be expressed when paired with:

74% Answer Correctly

a dominant trait

a recessive trait

a gene

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

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

75% Answer Correctly

a food chain

a biome

a community

a population
Solution

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

4

Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?

63% Answer Correctly

isotopes

ions

products

reactants
Solution

The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.

5

Traits represented by genes may be which of the following?

82% Answer Correctly

all of these

dominant

recessive

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.
