five different eukaryotic species
For each species:
Discuss how to identify the organism. This includes how you
could identify it in a lab, or defining visible
characteristics. (2/2, 2/2, 2/2, 2/2, 2/2
points).
Consider a physical description (how many legs, type of
skeleton, what does it look like, what color is it, what type of
hyphae, etc)
Describe a clinical disease this organism is responsible for,
and some signs and symptoms of such disease, as well as prevention
and treatment.
Discuss some epidemiological statistics of the disease, or
specific economic impact
Remember, these must include actual numbers and facts
Discuss an organism that could mimic this one, and how can you
tell the difference between the two?

If the five eukaryotic species have been provided and they are
unknown for their traits or the resemblance then the species can be
categorized in the different ways based on the different data which
can be provided for those species.
Molecular-level: If the molecular approach is considered then
the isolation of the RNA and Kozak sequence for the species is
checked which is the conserved sequence as per the species type is
a concern. No two species can have the same Kozak sequence which is
conserved for both of them.
Phonotypic-level: In this case, the organism's external
appearance can be studied on different aspects such as skin color,
legs, wings, etc. This is the vague analysis where the species can
have the identity or the similarity in some of the cases and due to
which it can only give the rough idea for the differences in the
species.
Epidemiology: The species origin can be studied after
characterizing the species or the similar species can be studied
related to the given unknown species based on the first two
characteristics and thus allowing to narrow down the gathering of
information on the historic or the past.
Clinical diseases: After the epidemiology it can be configured
that the various disease spreading ability of the species which has
been provided and thus they can be categorized and segregated on
that basis.
The protein synthesis in pro- and eukaryotic species resembles
each other to a large degree. In both pro and eukaryotic cells,
mRNA is used as template for incorporation of the correct amino
acids in the growing polypeptide chain.
a) List the main differences between mRNA from prokaryotic and
eukaryotic species
b) In contrast to prokaryotic cells, eukaryotic cells has
spliceosomes, what function do they have? and list the main steps
in the reaction
c) How many different codons code for...

Evolutionaray adaptation: a. identify a unique adaptation this
species exhibit. b. describe a selective pressure that may have
favored this adaptation.
Identify and discuss the five components of Michael Porter’s
Five Forces Analysis. How might these five components impact the
competitiveness of an organization?
You identify two bacterial species growing together in different
environments: species A is an
organoheterotroph and species B is a lithoautotroph. Below are
three environments (E1-E3) that both bacteria
can grow and reproduce in, different only in the one environmental
change highlighted, that you use to test the
assumptions of the Molecular Clock hypothesis. You create a
taxonomic tree comparing rRNA from one
environment (no parentheses) with another control environment
(parentheses). Assuming the theory is correct,
choose one prediction (A...
How many ways can a gardener plant five different species of
shrubs in a circle? What is the answer if two of the shrubs are the
same? What is the answer if all the shrubs are identical?
You isolate nuclei from three different eukaryotic species. You
treat the samples in exactly the same way (adding same amount of
enzyme, buffer and time) to partially digest the chromatin with
micrococcal nuclease, extract the DNA, and run it on a gel. You see
the pattern below:
