Answer: Attached below is the missing part of your question

answer

Mutant A

<em>1) Requires tryptophan in the growth medium or from a donor mutant </em>

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

Mutant B

<em>1) Requires histidine in the growth medium or from a donor mutant </em>

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

Explanation:

<u>Mutant A ( Over produces His and cannot produce Trp ) </u>

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

<u>Mutant B ( cannot produce His and overproduces Trp </u>)

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.

List 4 ways in which you can decrease your chances of catching the flu or cold
shutvik [7]
Hi there!

#1 Washing you’re hands after touching anything that may be dirty, or even just using the restroom.

#2 Disinfecting door nobs, handles, desks and things you may touch on a daily basis.

#3 Stay away from those you may think are sick.

#4 Having those around you remember to cover their mouths and noses while sneezing.

Remember to do this using the pit of you’re elbows NOT you’re hands. This can spread germs more easily.

Hope this helps you!

Viktor [21]

Answer:

The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water. ... So the carbons in the glucose become oxidized, and the oxygens become reduced.
