Answer:
Answer: Demand for cotton balls is usually determined based on the population size and the number of medical centers. The demand will vary depending on how much cotton is required per patient (which depends on their condition).
Explanation:
The population size would be calculated by multiplying current population rates by estimated future rates. These calculations can be difficult, since they require available data about birthrates, death rates, and migration patterns to determine current population growth.
The number of medical centers represents primary care points for patients that need more than just over-the-counter treatment. Population statistics are also used in calculating this figure because it incorporates total number of people sought medical attention each year, which relates to demand for medacins.

Option E
sensorineural hearing loss typically begins in high-frequency hair cells
Explanation:
In presbycusis, most old people cannot hear the high-frequency sounds, because of some loss of hair cells in their cochlea. unlike some other vertebrates like fishes and reptiles, these hair cells can be re-generated. However, in Humans, they cannot be.
As a result of these sounds that have higher pitches such as the buzzing of a mosquito, are muffled to them. Therefore, talking in a frequency is necessary, as this will aid the old people hear the medical technicians better.
Answer:
Lack of ADH increase urine volume and decrease urine concentration.
Explanation:
ADH is a hormone which is responsible for regulation of urine volume. The hormone is released in the blood from the posterior pituitary when the ion concentration in the blood becomes high.
This hormone acts on the nephron especially on distal convoluted tubule and collecting duct and increases their permeability towards water which in absent of ADH is impermeable to water.
This increased permeability allows the reabsorption of water from these sections which reduces the blood volume and helps in producing concentrated urine.
