Consider the scenario in which Mutants A and B are grown in a medium that contains His, but does not contain Trp. For this scena

rio, 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

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.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral
dimaraw [331]

Answer:

In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species

Explanation:

A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Rashid [163]
Blade
Thin, flattened section of a plant leaf that collects sunlight

Petiole
Thin stalk by which a leaf blade is attached to a stem

Mesophyll
Specialized ground tissue that makes up the bulk of most leaves; performs most of a plant's photosynthesis

Palisade Mesophyll
Layer of tall, column-shaped mesophyll cells just under the upper epidermis of a leaf

Spongy Mesophyll
Loose tissue beneath the palisade layer of a leaf

Stoma
Opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leaf

Guard Cell
Specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure

Transpiration
Loss of water from a plant through its leaves
