Epuloposcium is a very large bacterium. Large bacteria are unexpected because of slow rates of diffusion. One way that Epuloposcium overcomes this problem is: Select one:

a. The use of facilitated diffusion

b. The presence of a cytoskeleton to assist in transport

c. Extreme polyploidy - 1,000s of copies of the cell genome

d. Intracellular organelles to provide compartmentalisation

Expert Solution

Answer- c. Extreme polyploidy- 1,000s of copies of the cell genome

Explanation- Epulopiscium is largest known bacteria that has extreme polyploidy. This bacteria has 100-1000 copies of the genome so that bacteria can synthesize more gene products as genes are present in many copies. This bacteria can synthesize many different types of proteins at different sites in cell so that biomolecules are synthesized at different sites in cell.

Wrong options-

a. The use of facilitated diffusion- facilitated diffusion does not overcome slow rates of diffusion problem.

b. The presence of a cytoskeleton to assist in transport- in bacteria cytoskeleton is not used for transport but in eukaryotes cytoskeleton is used for transport.

d. Intracellular organelles to provide compartmentalization- it is bacteria so that intracellular organelles are not present in this bacteria. As it is bacteria compartmentalization is not present in bacteria and in eukaryotes due to membrane bound organelles compartmentalization is possible.

A mutation occurs in a bacterium. Because of this mutation, DNA synthesis occurs at a very low rate. Upon analysis, it is found to have normal levels of activity of DNA polymerase I and III, DNA gyrase, and ligase. It also makes normal amounts of the wildtype dnaA, dnaB, dnaC, and SSB proteins. The sequence of the OriC (the origin of replication) of its chromosome is found to be normal (wildtype). What defect might account for the abnormally low rate...

You are a bacterium living well in a community of other bacteria, phage and yeasts. Resources are partitioned well; cooperation is efficient and abundant. But what is this? One hundred outside bacteria are trying to enter and become established and this is not a welcomed event. How would you use your secretion system to defend your community and yourself? How would you also use your secretion system to support the existence and well-being of other microorganisms in your biofilm community?

a. Assume that Ajani did not buy a $30,000 car from Humbug because of the unexpected tax bill. If the MPC is .6, how much will Humbug reduce his spending from Tanaka? b. Humbug’s drop in spending causes a chain reaction which is illustrative of the multiplier effect. Assuming that each person in the chain spends sixty percent of any change in income on the person next in the chain, how much would Gonzales’ income be reduced by Ajani’s cancelled...

When unexpected inflation is zero, the corresponding unemployment rate is not zero because: A) the output gap is negative. B) the output gap is positive. C) structural unemployment and frictional unemployment are not zero. D) cyclical unemployment is high and positive. If an economy has an output gap of 0%, this means the economy is: A) suffering from hyperinflation. B) at its highest sustainable rate of production. C) experiencing cyclical unemployment. D) unsustainable in the long run.
