This level of taxon is the most specific and can reproduce with one another in nature and produce fertile offspring.
a) class
b)phylum
c) species
What is c) Species
This system is part of the plant that is made of stems (transport), leaves (photosynthesis ), and flowers (reproduction).
What is the shoot system?
This is a species on which other species in an ecosystem largely depend. If it was removed, the community would change drastically.
What is a Keystone species?
These structures show that two organisms have a common ancestor.
a) homologous
b) analogous
What is
a) homologous
What is the complimentary DNA strand of this ?

This "cat" is the most closely related to the Panthera leo.
a) Felis catus
b)Panthera unica
What is b) Panthera unica
This is the system in a plant that anchors the plant and takes in water and nutrients (minerals) from the soil.
What is the root system?
If there is 10,000 joules (amount of energy) in the bottom trophic level of the pyramid ( the producers), what is the amount available in the secondary consumer level?
Draw the pyramid if it helps you figure it out.
What is
100 Joules?
In cats, the bones in the legs involved in walking are very similar to the bones of whales' flippers that are involved in swimming.
Do these bones have the same structure or function? AND
Are they homologous or analogous?
What is
the same structure?
and they are homologous.

REMEMBER this saying (mnemonic)
Dear King Phillip Came Over For Good Soup.
These are vessels in the plant that carry water and minerals and travel only up from the roots to other parts of the plant.
What is xylem?
Which of the following causes the greatest disruption to an ecosystem....
a) Cutting down a small cedar tree to make holiday decorations.
b) Putting non-native species into a local waterway.
What is b) Putting non-native species into a local waterway.
This is when organisms best suited for their environment survive and reproduce.
a) evolution
b) natural selection
c) adaptation

b) natural selection

Mutation AAT-AAA
What is substitution?
True or False
An organisms scientific name is from the taxa, Genus and species. This is a universal naming system, which prevents confusion with languages.
What is TRUE?
This is the response from a plant when it responds to light. The auxin causes shoot cells on the shady side of the stem to elongate, thus the stem will bend toward the light source.
What is phototropism?
True of False?
Punctuated equilibrium is gradual changes over time, typically after a disturbance.
What is FALSE.
A single deer species leaves its current population and migrates across the river to join a population that resides on the other side of the river. What evolutionary mechanism does this describe?
Gene Flow.
Mutations are always harmful.
Mutations can be beneficial, harmful, or silent.
True or False?
Archaea and Bacteria are Eukaryotes.
What is False?
They are Prokaryotes.
This is an animal system that is responsible for filtering and removing metabolic waste.
What is the excretory system?
True or False
Primary Consumers are autotrophs.
What is false?
Which of these is evidence that two different species have a common ancestor.
a) different means of metabolisms
b) limbs have the same function but different structure
c) several genes with similar DNA sequences
what is
C) Several genes with similar DNA sequences.
