The right answer is E. Sodium  (with 140mmol/L)

Sodium is the most important element in the blood and extracellular liquids of the body.The needs of an adult subject are of the order of 1 to 2 g of sodium per day. The normal diet is much richer than our actual needs, about 4g, so it can largely compensate for the needs of an athlete or a runner.
Losses are majoritarly by feces and sweat. The kidney is able to reabsorb almost all the sodium that is filtered: urinary losses can be tiny.

Explain one adaptation that helps grasses succeed in grasslands
ehidna [41]

Answer:

Basal meristems

Explanation:

Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.

Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.

This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.

klasskru [66]


True.

The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.

Even though the earth system is a closed system, it self regulates through the subsystems  such as the water cycle and  carbon cycle.

The earth system is characterized by numerous overlapping cycles in which matter is recycled  over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.

Because there are many types of errors which can influence an experiment result like an instrumental error, personal error/human error.

The personal error is the error in measuring results or interpreting the results by the scientist due to some reasons like attention deviation or inability to take accurate measuring.
