Answer:
Explanation:
It is given that out of 40, total 5 specimen are selected.
Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by
Number of specimen with certain trait is equal to 3.
Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest 
specimen.
Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to
Answer:
The correct answer is : The opponent process theory
Explanation:
The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.
The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.
For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.
Thus, the correct answer is : The opponent process theory

The pairs of homologous chromosomes (the bivalents), now as tightly coiled and condensed as they will be in meiosis<span>, become arranged on a plane equidistant from the poles called the metaphase plate.</span>
