Answer:
Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .

Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.

Hypotonic - because there is a higher concentration inside the cell than outside of it
The type of stimulus following a behavior removes something that is unpleasant is the negative reinforcer.
Stimulus is any signal. This can be in the form of touch, smell, taste, etc. This stimulus triggers the nerve cells of the body that send to signals to the brain to generate a response. For example, when one person touches a hot utensil, the touch of heat acts as a stimulus, where the brain sends response in the form of instantly removal of the hand.
Negative reinforcement is the response towards a stimuli that has not yet been received. For example, taking a medicine before any disease appears is the acts of negative reinforcement.
