Transduction
T/F Antibiotics such as Penicillin, inhibit cell wall synthesis and work better on Gram + bacteria
True
T/F Male birds often perform a special dance or set of physical displays to attract females. This would be an example of a behavioral isolation mechanism.

Which includes a sexually transmitted organism and the parasite organism that cause African sleeping sickness?
Zooflagellates
Darwin's theory of natural selection to explain evolution is also known as
descent with modification
Sexual reproduction organs

Quantitative data
numerical data
obligate aerobe
organism that requires a constant supply of oxygen in order to live
obligate anaerobes
poisoned by oxygen
Birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because
the wings are not homologous structures with a common ancestral origin.
Translation
Process by which mRNA is decoded and a protein is produced
When the continents broke apart and separated, animals were separated by ocean. This lead to this type of speciation?
Allopatric Speciation
This group is characterized by a clublike structure called a basidium which produces basidiospores.
Basidiomycetes
A mushroom would produce a sexual spore known as
Basidiospore
Groups of interbreeding natural populations that are reproductively isolated from other such groups are called?
Biological Species
Water molds have a cell wall composed of __________?
Cellulose
A member of the green algae is
Chlamydomonas
This group is characterized by having cilia in at least one life stage?
Ciliates
Round shaped bacteria are called?

Condia
Analogous structures are evidence of __________?

Plasmogamy
An example of a filamentous green alga is ______________
Spirogyra
What groups are all parasitic?

Define dikaryotic
Stage that bridges the gap in fungal reproduction between diploid and haploid (fused cytoplasm, but not fused nuclei)
facultative anaerobes
can live with or without oxygen
Transduction
conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brains can interpret.
The term "mycorrhizae" is based on the Greek root words meaning
fungus and root
karyogamy
fusion of nuclei
obligate
to compel somebody to do something as a legal or moral duty
