Question Bank for Grade 10 Science

A change in the inherited characteristics of an organism over time is ________

• evolution.
• development.
• growth.
• ancestry.

The most recent ancestral form or species from which two different species evolved is known as ________________________.

• a common ancestor.
• an embryonic stage.
• development.
• evolution.

In stage one (top row) of these embryos, most of the embryos________

• look very similar.
• have very different features.
• show different stages of development.
• have only a tail if they are non-human.

What type of evidence is represented in the picture above:

• Fossils

• Biogeography

• DNA

• Homologous Structures

What type of evidence is shown in the image above?

• Fossils

• Homologous Embryology

• Homologous Structures

• Molecular Biology

What type of evidence are shown in the picture above?

• Fossils

• Comparative Embryology

• Homologous Structures

• Vestigial Structures

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural environment

• The organisms shown have similar structures and different functions which suggests they may have developed from a common ancestor

• The organisms shown have the same genetic diseases

• All vertebrate species have identical forelimbs

According to this data, the unknown species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

Body parts similar in structure and origin is an example of

• evolution

• embryology

• homologous structures

• variation

The LEAST evolved organism is found in

• Layer 1

• Layer 2

• Layer 3

• Layer 4
