Consider the scenario in which Mutants A and B are grown in a medium that contains His, but does not contain Trp. For this scenario, sort the descriptions that apply to Mutant A or B. Remember:
Mutant A: Overproduces His and cannot produce Trp
Mutant B: Cannot produce His and overproduces Trp

Attached below is the missing part of your question

answer

Mutant A

1) Requires tryptophan in the growth medium or from a donor mutant

2) Must form nanotubes to obtain it's required amino acid in this scenario:

Mutant B

1) Requires histidine in the growth medium or from a donor mutant

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario:

Explanation:

Mutant A ( Over produces His and cannot produce Trp )

1) Requires tryptophan in the growth medium or from a donor mutant ; This is because the Mutant is an auxotroph for tryptophan.

2) Must form nanotubes to obtain it's required amino acid in this scenario:

This is because growth medium of the mutant is supplemented with  histidine

Mutant B ( cannot produce His and overproduces Trp )

1) Requires histidine in the growth medium or from a donor mutant :

This is because Mutant B lacks the biosynthetic pathways necessary for histidine production

2) Does not need to form nanotubes to obtain it's required amino acid in this scenario: because the Mutant cell can easily take up the required amount of Histidine from its surroundings.

cuz they cant breath

explanation:

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
