Unit 3 Test Review - Natural Selection

What is natural selection?

• a living individual that can carry out life processes

• Process by which an organism that better adapts to their environment survive and reproduce

• Process by which a community better adapts to their environment to give traits to one another within their generation.

• the time between when an organism is born and when they reproduce

What is a common concern associated with GMOs?

• They are less resistant to pests

• They are more expensive to produce

• They may cause allergic reactions

• They have a shorter shelf life

Any inherited trait that gives an organism an advantage in its environment is called ___.

• a mutation
• an adaptation
• evolution
• natural selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Which of the following statements best describes what will most likely occur to the moth populations in the image?

• The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.

• The light moths will change their wing color to match that of the dark moths.

• The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.

• The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.

The purpose of selective breeding is to

• get bigger animals

• get smaller animals

• create animals with desirable traits

• create animals with bad traits

Increasing helpful traits to an organism is one way a breeder may use selective breeding.

• True

• False

Over time, honey suckle flowers develop a sweet smell to attract pollinators. This is an example of

• selective breeding

• extinction

• natural selection

• evolution

Selective Breeding is

• making organisms reproduce during times of stress

• a process to create an organism with desired traits from parents with those desired traits

• natural method of producing offspring with desired traits

• creating a new species

Organisms within a population have genetic differences in their traits called.

• Genotypes
• Variation
• Natural Selection
• Heterozygous
