With adequate hydration, what is the expected approximate, normal daily urine production of an adult?
kicyunya [14]

Answer:

With sufficient hydration of about 2liters daily, the normal urine volume expected of an adult is between 800-2000 milliliters

Explanation:

The normal range of fluid required by an adult is 2 liters daily. Urine is produced by the kidney and it account for the largest volume of water leaving the body.

The kidneys adjust the volume of urine ejected based on the body's water requirements; if the body is dehydrated, less urine is ejected and if there is sufficient or excessive hydration, more water is excreted as urine.

What is the answer to this question?"explain two difficulties an ecologist might have in counting a population of migratory bird
dimulka [17.4K]
<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>
