Andre45 [30]

Answer:

B) stain only the thicker peptidoglycan cell walls

Explanation:

Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.

He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.

Thus, Option-B is correct.

Sloan [31]

Answer: 3.

Explanation:

The concept is based on sexual imprinting which results from selection for recognition of conspecifics.

Sexual imprinting is the mechanism by which a young animal discovers the properties of a desired mate. Male zebra finches, for example, tend to favor mates with the presence of the female bird rearing them, rather than that of the birth parent when they're special.

A female zebra finch select a male that resembels her father with a red feather taped to his head for reprodcution because there are sufficient opportunity of sexual imprinting.

Hence, the correct option is 3.
