Three types of mutations.

What are insertion, Deletion, Substitution

100

A group of organisms that can reproduce with one another and produce viable offspring.

What is a species.

100

The role or function of an organism or species in an ecosystem. Also described as the habitat or specific area where an organism inhabits.

What is an ecological niche.
100

Give two types of symbiotic relationships.

- Mutualism

- Commensalism

- Predation

- Parasitism

100

A claim that states that the independent variable affects the dependent variable.

What is the alternative hypothesis.

200

What process can potentially occur in all species of living organisms and ultimately leads to an increase in genetic variation.

What is mutation.

200

Organisms of the same species which live in a particular geographical area.

What is a population?

200

Removal of this species can result in ultimate collapse of an ecosystem.

What is a keystone species.

200

Predation is usually short term for two reasons. What are these two reasons.

A species either dies or moves away.

200

Why is GFP expressed by E.coli cells after transformation with the pGLO plasmid.


Hint: Don't whine. THINK ABOUT WHAT IS CONTAINED IN THE pGLO PLASMID.

Presence of arabinose activated the ara operon regulatory sequences.

300

Universal stop codons.

What are UAA, UGA, UAG

300

External conditions such as resource availability, predators, or environmental conditions that affect an organism's ability to survive.

What are selective pressures?

300

The type of growth that is experienced when invasive species are first introduced to an environment. *Answer must include reasoning*

What is exponential growth due to lack of predators and outcompeting natural inhabitants.

300

Give two fundamental theories that show evidence for the claim that all organisms share an evolutionary ancestor as described in the endosymbiotic theory.

What are:

- triplet codons in the genetic code

- glycolysis and cellular respiration

300

In our E. coli experiment, what scientific principle gave E. coli the antibiotic resistance when plated on ampicillin.

What is transformation of the pGLO plasmid.

400

The protein expressed by a mutant allele is 2020 amino acids shorter than the wild-type protein. What would explain why a shortened protein is produced.

A premature stop codon caused translation to end early.

400

Topsoil is the fertile material vital to life. This method leads to topsoil depletion, increased used of fertilizer and loss of biodiversity. Polyculture agriculture is a potential alternative.

What is monocropping.

400

What is the equation for logistic growth rate?

rmax(N)(K-N/K)


rmax - growth rate per capita

N - initial population

K - carrying capacity

400
List 4 mechanisms of evolution.

Genetic drift

Gene flow

Natural selection

Mutation

400
In our experiment where we transformed E.coli bacteria to contain the pGLO plasmid, what should we see on a control plate that shows nontransformation in the presence of ampicillin.

*Hint: This question is not referring to bacterial growth, rather it is referring to contents on the plate

What is LB agar with ampicillin and no plasmid added

500

Explain how functional RNA is made in eukaryotes.

Portions of RNA known as intervening sequences (introns) are removed.

500

Enzymes are catalysts within the body. Essentially, they work by lowering this reacting energy.

What is activation energy.

500

A population contains four trophic levels. Assuming that at the secondary level, there are 50,000 kJ of energy. How much energy should be available at the fourth trophic level.

500 kJ of energy

500

What evidence supports that evolution has occurred between ANY group of organism.

*Hint - emphasis on the word any.

What is change in allele frequency.

500

In our experiment, what procedure did we follow to ensure that transformation had occurred.

*Hint: Points will not be awarded for obvious end result answer containing the word glow.

Spread initial colonies from plate onto ampicillin containing plates and then tested for fluorescence.
