dimaraw [331]

Answer:

Termites have cellulose-digesting protists in their guts.

Explanation:

Termites are able to access nutrients contained in cellulose due to their mutualistic association with some cellulose-digesting protists such as <em>Trichonympha</em> and M<em>ixotricha</em>. The protists produce cellulase in addition to other glycolytic enzymes that work together to convert cellulose to malate.

The malate produced is further metabolized to produce $CO_2$ , hydrogen, acetate and energy in the form of ATP.

The protists get sheltered in the termite's gut in return.

lakkis [162]

Answer:

550 milliliters of water is needed.

Explanation:

the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
