The study of life.

What is biology?

100

Classify the following genotypes.

Gg

Hh

Tt

Aa

What is heterozygous?

100

These scientists discovered the structure of DNA.

Who were Watson and Crick?

100

This scientist proposed the theory of natural selection.

Who was Darwin?

100

Put the following terms in order from MOST SPECIFIC to MOST BROAD.

community, ecosystem, species, biome, biosphere, individual

individual, species, community, ecosystem, biome, biosphere

200

Describe 2 difference between eukaryotes and prokaryotes.

Eukaryotes:  linear DNA, DNA in nucleus, have a nucleus

Prokaryotes:  circular DNA, DNA in cytoplasm, nucleus absent

200

Classify BOTH of the following genotypes.

Row 1:  AA, GG, TT, HH

Row 2:  aa, gg, tt, hh

Row 1: homozygous DOMINANT

Row 2: homozygous RECESSIVE

200

Describe the difference between transcription and translation.

Transcription produces RNA from DNA.  Occurs in nucleus.

Translation produces protein (sequence of amino acids) from RNA.  Occurs in ribosomes/cytoplasm.

200

Darwin first discovered _______ in _______.

Fossils / Argentina
200

Describe the difference between autotrophs and heterotrophs and give an example of each.

autotroph - makes its own food (ex. plants)

heterotroph - gets energy / food from another source (ex. lion, human, bear, squirrel)

300

Describe the difference between sexual reproduction and asexual reproduction.

Sexual produces genetic diversity.

Asexual makes copies / no genetic diversity.

300

A purple daisy and white daisy produce some offspring that are purple only and some that are white only.  Classify this type of inheritance pattern.

What is complete dominance?
300

Draw a nucleotide.  Label all 3 parts.

300

Describe and give an example of natural selection.

An organism adapting over time to their environment that increases chances of survival and successful reproduction.

Example:  birds acquiring webbed feet in an environment after a flood

giraffe necks becoming longer over time

peppered moth wing color changing due to pollution

300

Describe a keystone species and give an example.

A species that plays a vital role in an ecosystem to maintain balance and control of populations of other organisms

ex.  wolves of Yellowstone Park

400

Describe the difference between unicellular and multicellular.

Unicellular - single cell

Multicellular - more than one cell

400

A white daisy and purple daisy produce pink offspring.  Classify this type of inheritance pattern.

What is incomplete dominance OR blended inheritance?

400

Answer 1: These are spliced together to make the final RNA product.

Answer 2: These are spliced out / removed from the final RNA product.

1:  exons

2:  introns

400

Describe the difference between analogous and homologous structures.

analogous - organisms that evolved along different paths that have structures with similar function but different appearance / structure

homologous - organisms that evolved along similar paths that have structures with different functions but similar appearance / structure

400

These limiting factors include but are not limited to disease, predation, space, and resources.

What are density-dependent limiting factors?

500

Name 3 characteristics of living things.

-need energy to carry out processes

-can reproduce

-can grow

-respond to stimuli

-dependent on environment

500

In a species of mice, black fur is recessive and white fur is dominant.

Complete a cross between a male mouse with black fur and a female mouse heterozygous for white fur. Include genotypic and phenotypic ratio for the offspring.

Punnett square to be drawn on board.


White - 50%    Black 50%

Bb - 50%

bb - 50%

500

This enzyme unwinds the DNA double helix for replication to begin.

What is helicase?

500

This scientist developed the naming system for organisms.

Who was Linneaus?

500

Name the 3 symbiotic relationships, describe what they are, and give an example of each.

mutualism - both organisms benefit (clownfish and sea anemone)

commensalism - one benefits, the other is unaffected (manta ray and small aquatic organisms)

parasitism - one benefits the other is harmed (tick on a human or dog)
