A question is something someone asks. A hypothesis is like a person's theory.

The correct answer is that the following is true concerning sources of water pollution is option a. Mine wastes and heavy metals become water pollution through stormwater runoff.
Mine wastes and heavy metals become water pollution through stormwater runoff. As water contaminates by producing coppers, sulfate, sodium as the toxic elements contaminating the water. The chemicals are released from mining activities by contaminating soil, air, by causing pollution.
<h3>What are sources of water pollution?</h3>
The sources of water pollution are :
- mining
- industrial wastes.
- marine dumping
- burning of fossils
- chemical fertilizers.
Hence concluded that water pollution can cause be caused by Mine wastes and heavy metals becoming water pollution through stormwater runoff.

<span>The correct answer is paleomagnetism. This is mostly done, however, in regards to the magnetic properties found in the earth itself, like in rocks and minerals or ores, and less with the actual magnetic poles of the earth, but it does encompas it too. It is very useful in the science of tectonic movements and discovering the chonology of geology.</span>
Answer:
The correct answer is d. eukaryotes almost always produce polycistronic mRNA
Explanation:
In eukaryotes one transcription unit contains the information of only one gene which codes for only one protein or polypeptide therefore eukaryotic mRNA is called monocistronic mRNA.
In prokaryotes transription unit contains set of genes adjacent to each other which are transcribed together and codes for multiple proteins. So prokaryotic mRNA is called polycistronic mRNA.
Almost all messenger RNA present in eukaryotes are monocistronic mRNA because eukaryotes are more complex than prokaryotes and require modification at many stages which is easily possible with monocistronic mRNA.
