mutation

camouflage

adaptation

Which organisms are most likely to survive?

the best adapted

the fastest

the strongest

the most domesticated (tamed)

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

Dark moth

Light moth

Both will be equally successful

Neither will be successful

These moths are all the same species. The differences between their wings is an example of ________________

Natural Selection

Variation

Homeostasis

Extinction

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

artificial selection

inbreeding

outbreeding

Evolution works by

individuals changing to suit their environment

Individuals learned new traits and pass them on

sudden change in the environment cause a species change

small changes pass down through many generations

Mutations are important because they bring about

death of the organism in which they develop

genetic variation needed for a population to evolve

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

Natural selection results in change in a population's _____________ traits over time.

inherited

acquired

Individuals undergo evolution.

True

False

10.

The ability of an organism to survive and reproduce in its specific environment

diversity.

evolution

adaptation

fitness

11.

Which of the following is a factor in natural selection?

Individuals of species compete with one another to survive.

All species are genetically diverse.

Individuals better able to adapt to changes leave more offspring.

All are correct

12.

A/an ________ is an injection of a weakened form of a pathogen to help the individual gain immunity from a disease.

Virus

Vacuum

Vaccine

Antibiotic

13.

You are a doctor and Little Billy is in your office with the flu. His mother wants you to prescribe an antibiotic. Which would be the best response?

"Absolutely, get that kid an antibiotic!"

"Actually, he just needs to take a painkiller."

"Unfortunately, antibiotics do not work against viruses like the flu."

"Give him a vaccine and he will feel better right away!"

14.

What do viruses need to reproduce?

they need genetic material

They need a host cell

They need bacteria

They need insulin

15.

What is the first step to both cycles?

The virus attaches to a host

the virus injects genetic material

the host gets sick

the cell is destroyed

16.

When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?

lytic

lysogenic

cell cycle

DNA replication

17.

What is shown here?

Lysogenic Cycle

Lytic Cycle

Binary Fission

Conjugation

18.

What process is this?

phagocytosis

lytic cycle

lysogenic cycle

formation of antibodies

19.

What happens in the lysogenic cycle?

Virus goes in and leaves the host cell

Virus quickly kills the host cell

Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time

Bacteria injects DNA into a host cell

20.

Fully grown parent cells split into two halves resulting in two daughter cells with the exact DNA as the parent.

Binary Fission

Budding

Fragmentation

Vegetative Reproductions
