Answer:
1.) Stimulus ----> A change in the system or environment.
2.) Response ----> A result or event that occurs because of a change in the system.
3.) Positive Feedback ----> The goal is to amplify the response until the stimulus is removed.
4.) Negative Feedback ----> The goal is to reduce the stimulus and return to homeostasis.
Answer:
The right order is
incomplete dominance ==> 2
polygenic inheritance ==> 3
codominance ==> 1
Many physical characters depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
Codminance: The phenotype of each allele is expressed simultaneously in heterozygotes.
Incomplete Dominance: An intermediate phenotype is obtained between the two dominant alleles.
It depends on which forms they come in.
