Answer:The Drive-Reduction Theory
Explanation:
The Drive-Reduction Theory, a principle first proposed by the psychologist Clark Hull in 1943 to explain the situations under which learning can take place
It describes an organism's reaction to a situation where his physical needs are questioned or challenged. Such organism can develop new responses when it is motivated by a need and strives to meets that need. In a nutshell, it means that Learning depends on how an organism alleviates or satisfies it's drive;for example Lara knows to get a glass of water because she gets the feeling of being thirsty which motivates her to reduce her thirst by drinking water- An example of drive reduction theory.
According to this theory, there are physiological needs (in this case water), that occurs in an organism that creates an unrest( need for water) and motivates the organism to satisfy the need to reduce such disturbances. (ie to drink water).

Answer:
50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
Explanation:
The black chickens are the dominant allele and the white chicken are the recessive allele. Since the black chicken is dominant, Let the genotype of the black chickens be (BB) and the genotype of the white chicken be (ww).
If the Black and white chicken are cross bred and the eggs hatched are black with white speckles, i.e (Bw). The genotype of all the hatched chickens would be (Bw). Where Bw is speckled chicken.
If the hatched chicken with genotype (Bw) are interbred, the resulting hatched chickens genotype would be BB, Bw, Bw and ww for four offsprings. This shows that 50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
