The correct answer as to why some scientists believe that RNA, rather than DNA, was the first genetic material would be that RNA has both information storage and catalytic properties.
Other options are cannot be correct because:
- RNA cannot replicate itself unless it is in a living host.
- RNA containing Uracil instead of Thymine has no effect on being the first genetic material or otherwise.
- There is no clear evidence to show that all of the protocells on early Earth contained RNA
The fact that RNA has the capacity to store information as well as catalyze important biological processes made it a plausible candidate as the first genetic material. DNA has the capacity to store information but lacks catalytic properties, unlike RNA.

<u>Answer:</u>
The most appropriate answer option is: D) Saprophytes return organic material to the soil for use by living organisms.
<u>Explanation:</u>
A saprophyte, also known as a saprobe or saprotroph, is an organism (fungi) which feeds and grows on decomposing organisms. We also know that it secrete enzymes that digest components of cell walls, such as cellulose and lignin.
Saprophyte is an important part of the biogeochemical cycle as it decomposes the bodies of the dead organisms, recycles them and releases nutrients into the soil to be used by the living organisms.
