Answer:
they're called trace fossils
Answer:
Building desalination plants and using rain gauges.
Explanation:
Using the process of elimination, seismographs are incorrect because they measure earthquakes and obviously earthquakes have nothing to do with droughts (ok, maybe a little bit). Snowplows are used to plow snow, so the remaining answers should be correct.
Answer:
a)This is RNA polymerase performing transcription
Explanation:
We can see that the purple molecule is attached to a DNA molecule, and is producing an mRNA molecule from a template strand. This is the process of transcription
The enzyme that carries out the synthesis of an mRNA molecule is RNA polymerase.
If the molecule was a ribosome performing translation, we would expect a polypeptide chain to be produced rather than an mRNA, and that the template molecule would be mRNA
If the molecule was DNA polymerase, it would synthesising a DNA strand not mRNA
If the molecule was a DNA repair enzyme, it would be correcting errors, not synthesising mRNA.
