Question

Is this correct? 1. True false correction questions. Mark as T if true and F if false. If a statement is false, you will need to correct it in order to receive credit for your answer. There could be more than one error in a statement. Your corrections must be substantial, meaning that it is not ok to remove or add a "not", or to mark something out but not replace it unless it is unavoidable. Make sure you replace the incorrect portion to get credit. If something is underlined, it cannot be changed. Tlus and Staphylococcus will hold the primary stain during the iodine step, whereas Escherichia coli will not; this allows gram + bacteria to be distinguished from gram- bacteria. FSaureus and other gram + bacteria do not have any membranes as part of the cell walls; their cell walls contain teichoic acid, which has a full positive charge from the phosphorus present in the molecule. negahive

Explanation / Answer

1. True

2.False

S.aureus and other gram + bacteria do not have any membranes as part of the cell walls;their cell walls contain teichoic acid,which has a full negative charge from the phosphate present in the molecule.

3.False

A capsule is made up of polysaccharides and polypeptides and can protect against engulfment and subsequent degradation of bacteria by macrophages.

4.False

Water can form hydrogen bonds with the O's bonded to a hydrogen present in carbohydrate found in some capsules;the oxygen in the water because it is electronegative pulls enough charge from the hydrogen to have a slightly negative charge.
