To analyze:
Why fossil fuels are considered non-renewable sources of energy.
Introduction:
Fossil fuels are hydrocarbons that have formed from plant and animal remains over millions of years.

Explanation of Solution
Fossil fuels have formed from the remains of plankton, plants and animals that died millions of years ago. These organisms have slowly decomposed and remained under heat and pressure, underground, for millions of years. Since the time required for formation of fossil fuels is so long, they are considered non-renewable. The fossil fuels we use today will not be replenished for many millions of years, maybe even until humans go extinct.
Fossil fuels take millions of years to form from the remains of organisms. The fossil fuels we use today is not likely to be replenished for many millions of years to come. This is why they are called non-renewable fuels.

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
