Can nonrenewable resources be used sustainably? a. no, there's a finite amount of nonrenewable resources b. yes, nonrenewable resources are always beneficial for the environment c. yes, as long as use doesn't exceed availability d. no, there are only negative effects of using nonrenewable resources

The correct answer is C: Yes, as long as use doesn't exceed availability.

Explanation:

Non- renewable resources cannot be used permanently, but these resources can be used sustain-ably over a period of time to meet their needs. The reason is that these non-renewable resources such as oil, gas, and fossil fuels, are being used at a larger rate, but their production is quite slow beneath the earth surface.

Therefore on the surface, it is not possible to use them sustain-ably except exceeding the limit as they are running out.

For example, in 19th-century whale oil was used to meet the energy needs, but gradually this species became distinct, and its population couldn't be protected and restored by human beings.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
