PLZ HURRY! I'm being time What is the approximate height range of the : Troposphere to Stratosphere to Mesosphere to Thermosphere to

Troposphere 0 to 10 km

Stratosphere 10 to 50 km

Mesosphere 50 to 90 km

Thermosphere 90 km 600 km

I think this is the right answer I am not so confident on the 600 km part though.

Explanation:

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
