Answer: Conditioned stimulus.
Fear conditioning refers to a learning behaviour in which an aversive stimulus is paired with a neutral stimulus, up to the point in which the neutral stimulus elicits the same response as the aversive one, even when not paired together.
Before the experiences, the doctor was a <u>neutral stimulus</u> because his effect did not depend on previous experience. The <u>aversive stimulus</u> was the shots. The pairing of the doctor with the shots repeatedly elicits the <u>conditional response</u>, which is the crying. It also turns the doctor into a <u>conditioned stimulus</u>.

Answer:All individuals, whether rich or poor, are dissatisfied with their material well-being and would like more.
Explanation: People who face poverty and who have no proper shelter , food or even proper clothes to wear are always yearning for a life that is better than that which they are experiencing. Their wishes and desires always exceed the available resources so there is always scarcity in this case.
At the same time those who are wealthy also do not have all the resources that they all wish they could have , no matter how much money one possesses in those wealthy nations but it is never enough to fullfil all those things that each individual consider to be worthwhile.
Each individual person in whatever state of economy they find themselves in, there is never a point where all the resources seems to fulfill everyone's desires or wishes in that country or nation.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be: 9:3:3:1.
<h3>What is a phenotype ratio?</h3>
- The phenotypic ratio refers to the proportion of offspring that exhibit a specific trait or set of traits. A test cross can be used to ascertain the frequency of a trait or trait combinations that will manifest themselves based on the genotypes of the progeny.
- The ratio of various phenotypes found in a cross's progeny is known as the phenotypic ratio. Comparisons using numbers are ratios. For instance, the proportion of apples to oranges would be 3:2 if someone had three apples and two oranges.
- We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the expression and appearance of the alleles.
- Phenotypes include things like height, wing length, and hair color. In addition to measurable traits that may be observed and tested in a lab, phenotypes also include blood cell or hormone levels.
