The shopper should first ask if this claims created by the newspaper is true and is backed up by actual facts. While apple cider and honey do have positive benefits, it is not the answer to all ailments.
Assuming that everything said was true, the shopper then must know whether or not he/she has allergies to apple cider and honey like itching, rashes, difficulty in swallowing, etc.
Lastly, the shopper should ask how much apple cider and honey should he/she take. Too much of both can lead to adverse side effects. If he/she were to consume apple cider and honey exclusively, then they should visit a doctor or a nutritionist in order to get the right amount of intake.
Answer:
The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.
Explanation:
At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is
A=0.5
a=0.5
With those frequency, the expected percentage of offspring with dominant genotype will be:
AA= 0.5 * 0.5 = 0.25 = 25%
The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.
Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
