Answer #1

Bacteria colony can be described as mass of bacteria which is visible and originate from a single mother that grow on solid media. All the bacteria are genetically similar as they originate from same mother cell.

A colony of the same organism appear different on a streak plate versus a pour plate because streak plate method allow the growth and quantification of microaerophiles means this method have sufficient oxygen supply whereas pour plate method does not allow the this and used for isolation of pure culture.

You inoculate two different nutrient broth (NB) tubes with the same bacterial type from two different sources - plates culture and liquid culture. The NB culture incoculated from the plate culture shows more growth as revealed by the greated amount of turbidity (cloudiness) compared to the NB inoculated from the liquid culture. Suggest a couple of reasons why this difference occurred.

When a eukaryotic organism (such as a human) gets a bacterial infection, it can be treated with antibiotics. Antibiotics work by targeting prokaryotic cells without targeting eukaryotic cells. This is possible due to molecular differences between the two cell types that enable specific targeting of molecules in prokaryotic cells but not eukaryotic ones. The effects of different categories of antibiotics are listed below. For each one, explain how this would affect prokaryotic cells and why. Some antibiotics disable ribosome function....

Why is ATP not worth the same amount in different cell types (i.e. have a different ΔG) in multicellular organisms? Electrostatic repulsion between phosphate groups within a molecule of ATP. Different concentrations of ATP present. Different concentrations of ADP and Pi. Not all cells in a given organism are capable of oxidative phosphorylation.
