1.
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.

evolution

population
5.
What is natural selection?
a)
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
b)
When individuals survive and reproduce at a higher rate than others in the same population due to some environmental pressure

Process by which populations have become adapted to their environment over time
d)
Specialized structures and behaviors that aid in survival
6.
What are adaptations?
a)
Sharp reduction in population size due to an environmental disaster, often results in loss of variation
b)
When individuals survive and reproduce at a higher rate than others in the same population
c)
Process by which populations have become adapted to their environment over time

Specialized structures and behaviors that benefit the organism and aid in survival
7.
If an organism has a vestigial structure, that structure likely once had a function in a(n)

Some animals are able to see in ultraviolet (UV) light. Bees for instance can see Green and Blue and UV, but no Red, but butterflies and birds can see Red, Green, Blue and UV. Why would a plant need these special ultra violet markings?

Blue mussels with thick shells grow in larger colonies than mussels without thick shells.
c)
Blue mussels with thick shells catch more food per day than mussels without thick shells.

Superbugs survive antibiotics and reproduce

We have always had the same amount of superbugs; modern media just discusses them more.
d)
There is no reliable data on the origin of super bugs.
20.
Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?
a)
Individuals will only create offspring well-suited to the climate change
b)
The individuals would produce more offspring

Individuals better suited to the new climate will help less-suited individuals survive
