Answer:
b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.

Explanation: hope this helps if it not right pls tell me
Answer:
Grass

Answer:
Drive-reduction theory
Explanation:
Drive reduction theory is a motivation theory which is based on the principle that organisms are born with certain psychological needs and that they experiment a state of tension when these needs are not satisfied.
This state of tension pushes them to find a way to satisfy those needs, and when those needs are satisfied again, drive is reduced and the person returns to a state of homeostasis and relaxation.
According to this theory, <u>motivation happens when we experiment the state of tension and it's this motivation that drives us to satisfy our needs and be able to feel better. </u>
Dr. Williams is a psychologist who believes that motivation is produced when we feel an uncomfortable internal state that pushes us to find a way to feel better.
In this case, Dr. Williams thinks that our motivation originates from an uncomfortable state (state of tension) that pushes us to find a way to feel better (in order to reduce the drive and be back to homeostasis).
We can observe that Dr. Williams belief is very similar to the drive-reduction theory.
Note:
<u>a) Incentive theories of motivation state that people are motivated by incentives that are given to them (either internally or externally) when they do a expected behavior.</u>
<u />
<u>b) Maslow's hierarchy of needs states that our needs are based on a hierarchy in form of pyramid in which we first need to satisfy the needs at the bottom (physiological needs) to be able to proceed with the other needs that are higher on the hierarchy until we reach the self-fulfillment needs. </u>
<u />
<u>d) Instinct theory states that we are driven by instinct that we need to satisfy in order to experience balance and homeostasis. </u>
