Answer:

The correct answer is a. Pseudomonas aeruginosa would be colorless on EMB

Explanation:

Pseudomonas aeruginosa is a gram-positive bacteria that is rod shape. It shows a few nutritional requirements and can even adapt to those conditions in which the other bacteria can be adapt.

It is non-fermentative bacteria so it does not ferment lactose and other carbohydrates. As EMB agar contains lactose and some dye, therefore, the lactose fermenting bacteria ferment the lactose and show good growth and color change.

But as Pseudomonas aeruginosa is a non-fermentative bacteria it does not ferment lactose and does not show any color and forms a colorless colony. Therefore the correct answer is a.

If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, wh

AleksandrR [38]

The answer is <span>A. The two animal species are very closely related.

If the two animal species are very closely related, that means their genome information is very similar and that information for embryonic development is also very similar, but it will not be identical. Stages of embryonic development from the beginning to the end are same only in the same species. In different species, they will differ in lesser or greater extent which depend on how closely this different species are related.</span>
