The crust of the Earth can be thick in some spots and thin in others.
The answer is <span>B. The offspring would not cross-fertilize often with other roses.
Scent and colour of the flowers are important for pollination because they will attract pollinators. Flowers </span>with no scent and small, pale petals will attract much <span>fewer </span>pollinators than flowers <span>with scent and large coloured petals</span>. This means those bushes would not cross-fertilize often with other roses.
However, they would not die from a lack of pollinators, nor would produce seeds by asexual reproduction. Also, they would not yield more fruit than the parent rose, their fruit would probably be very small,
Answer: Discriminative stimulus
Explanation:
A discriminative stimulus is associated with reinforcement or punishment, that exerts control over a particular form of behavior. The subject discriminates between closely related stimuli and elicits a specific behavior only in the presence of that stimulus. T<u>his stimulus increases the probability of a given response</u> because of their historical correlation with the availability of reinforcement for the response.
In this example, the hungry rat gets food if it presses a bar only when the light is on. The rat learns that is most likely to request this food in the future in the presence of this light, because historically, the request has been reinforced in the presence of this light. <u>The light in the example became a discriminative stimulus and it evokes the response.</u>
