Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
Answer: Having a non-functional vestibular apparatus.
Explanation:
Motion sickness is a feeling of sickness that is caused by the movement. It occurs in a vehicle like boat, car, train or bus. It can also occur in the amusement rides. This is not life-threatening.

Answer:
the next step is to multiply the result by 5/9.
Explanation:
Below, the formula to convert Farenheit degrees to Celcius.
T(°C) = (T(°F) - 32) × 5/9
If barbara already subtracted 32 from 78, now the next step is to multiply the result by 5/9.
T(°C) = (78°F - 32) × 5/9 → T(°C) = (46) × 5/9 = 25.55°C
