The table here is based on the published results of the study discussed in the chapter. It shows the number of bacterial phylotypes (kinds of bacteria) that were found on a particular percentage of people. a. How many bacterial phylotypes were found on only 10 percent or fewer of the people sampled? How many were found on more than 90 percent of people? b. How many phylotypes were found on more than half of the people sampled? c. Describe in one or two sentences the frequency of phylotypes found in the study. Were most phylotypes rare or common?
For this assignment you will create a dichotomous key to
help you Identify Bacteria (which are a pain in the bum to
identify on the species level.) We will be focused on the
general terms of bacteria and the only Phylum that will be
addressed is the Cyanobacteria.
Use the following to create a dichotomous key to begin to
identify Bacteria:
BACTERIA
Bacillus
Coccus
Spirillium
Phylum Cyanobacteria
Gram (+) (-)
Root nodules
To Begin use the following question:
Does the organism exhibit a membrane bound
nucleus?

Experimental populations (average) 1.8 - 1.6 1.4 1.2 - Ancestral population 1.0 5000 10 000 15 000 20 000 Generation In this eight-year experiment, 12 populations of E. coli, each begun from a single cell, were grown in low-glucose conditions for 20 000 generations. Each culture was introduced to a fresh growth medium every 24 hours. Occasionally, samples were removed from the populations, and their fitness in low-glucose conditions was tested against that of members sampled from the ancestral (common ancestor) E. coli population. Which of the following is less likely to promote bacterial survival over evolutionary time in a low- glucose environment? Increased sensitivity to, and ability to move toward, whatever glucose is present in its habitat Increased ability to synthesize glucose from amino acid precursors Increased efficiency at transporting glucose into the cell from the environment Increased ability to survive…arrow_forwardBacterium A Bacterium B Bacterium C Bacterium D A Phylogenic Tree is a way to show the relationships between species, the way a family tree shows relationships between people.
