Question

select the text from the paragraph that best helps you understand that metabolism means the set of chemical reactions occurring within a living organism. there may be more than one correct choice.

the tardigrade, or water bear, is less than two millimeters long—tiny enough to be preyed upon by other microscopic creatures. however, these minuscule invertebrates are extraordinarily widespread and resilient. tardigrades have been found on all seven continents and in an incredible variety of environments, from hot springs to arid deserts to icy mountaintops. they can even survive in the vacuum of space, as a 2007 study revealed. how do these creatures survive without water, warmth, or even air? when resources are scarce, a tardigrade undergoes cryptobiosis, a temporary reduction of its metabolism to nearly undetectable levels. with its life - sustaining chemical processes decreased to 0.01% of their normal levels, the tardigrade can survive under even the harshest circumstances, reviving when conditions improve.

Explanation:

The text "With its life - sustaining chemical processes decreased to 0.01% of their normal levels" helps understand that metabolism is related to chemical processes (as "life - sustaining chemical processes" can be associated with the set of chemical reactions) within a living organism (since it's about the tardigrade's processes).

Answer:

With its life - sustaining chemical processes decreased to 0.01% of their normal levels
