Unit 3 Variation and inheritance

An illustration and a dichotomous key are given. What is the correct classification for this organism?

• Class Insecta

• Order Araneae

• Order Amblygygi

• Order Scorpiones

Differences between members of the same species are called

• predators

• selections

• traits

• variations

Which of the following is an example of Inherited variation?

• Eye colour

• Skin colour

• Blood type

• All of the above

All living things that are best adapted to their environments will be more likely to survive. This idea is known as _____________________ ____________________.

• Adaptations

• Evolution

• Natural Selection

In 1859, Charles Darwin proposed a theory based on the concept of natural selection. His theory explains the evidence of the gradual changes of all organisms over millions of years. This theory is known as the Theory of __________________.

• Mutation

• Natural Selection

• Evolution

• Adaptations

A characteristic that a living thing gets from its parents

• inherited trait

• physical behavior

• learned behavior

• acquired trait

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection

• inbreeding

• artificial selection

• outbreeding

What process is being shown in this image?

• Variation

• Selective Breeding

• Natural Selection

Domesticated dogs are an example of:

• Natural Selection

• Selective Breeding

What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Lights moths will change their color to match dark moths.
