A very persistent pollutant would

A. Biodegrade immediately

B. Be the easiest kind to remove

C. Only be made up of natural elements

D. remain in the environment for a long time

D. remain in the environment for a long time

Explanation:

Persistent organic pollutants are known to be or can be described as carbon-based chemicals that persist in the environment for a long time, are damaging to the environment, wildlife, and people, and can be spread over long distances. This means that , they are resistant to environmental degradation through chemical and biological processes.

The examples of persistent pollutants can be grouped into three, these are

* Pesticides: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene;

* Industrial chemicals: hexachlorobenzene, polychlorinated biphenyls (PCBs); and

* By-products: hexachlorobenzene; polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDF), and PCBs.

In conclusion, the persistent pollutants have the ability to remain in the environment for a long time.

i do not know and i have a 100 in this class

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
