Introduction to Biology

1. Ultimately, all scientific knowledge comes from:
experimentation
observation
textbooks
both experimentation & observation

2. A hypothesis must be:
proven correct
testable
observed
experimental

3. A scientist testing the affects of a chemical on apple yeild sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent variable in the experiment?
the chemical
the number of apples
the first orchard
the second orchard

4. The orchard sprayed with the chemical yeilds an average of 60 apples per tree, the other orchard yields an average of 40 apples per tree. Based on the data, the scientist would:
report his data
test the chemical on other plants
determine that the chemical increases apple yield
determine that the results were inconclusive

5. In order for the apple tree experiment to be valid scientifically, both orchards must:
receive the same amount of sunlight
receive the same amount of water
have the same species of apple tree
all of these

6. Theories help scientists to:
explain large bodies of data
prove hypotheses
determine truth from lies
propose new ideas about how the world works

7. If a theory is challenged by new evidence, which of the following could occur?
the theory could be altered
the theory is accepted, not the evidence
the evidence is wrong
a vote is taken on whether to accept the new evidence

8. All living things must:
move
have two parents
eat food
maintain homeostasis

9. The mechanism by which evolution occurs is called:
creationism
natural selection
interdependence
metabolism

10. The smallest unit capable of carrying out life functions is:
a cell
tissue
DNA
blood

Quiz Viruses

%CODE1%

Name:

Viruses

True/False

Indicate whether the sentence or statement is true or false.

Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction.

Some viruses have a membranous envelope surrounding the protein coat that helps them gain entry into host cells.

Viruses consist of RNA or DNA surrounded by a coat of protein.

Prions are the smallest known particles that are able to replicate.

A virus can only reproduce by controlling a cell.

Once a virus enters either a lytic or a lysogenic cycle, it cannot change to the opposite type of cycle.

Prophages and proviruses can both enter lytic cycles and destroy host cells.

People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system.

Smallpox is caused by bacteria.

10.

Chickenpox and shingles are caused by the same virus.

a.	lytic	c.	neither lytic nor lysogenic
b.	lysogenic	d.	lytic and lysogenic

18.

A prophage differs from a provirus in that

a.	a prophage contains DNA, while a provirus contains RNA.
b.	a prophage is formed during a lysogenic cycle, while a provirus is formed during a lytic cycle.
c.	a prophage contains DNA found in the infecting virus particle, while a provirus contains DNA produced from viral RNA.
d.	a prophage becomes integrated into a host cell’s DNA, while a provirus cannot become integrated into a host cell’s DNA.

19.

Which of the following is not a virus linked to cancer?

a.	Ebola	c.	hepatitis B
b.	human papillomavirus	d.	Epstein-Barr

20.
