Answer: Option A.
Electrons,carbon and energy.
Explanation:
Chemorganoheterotrophs are organisms that uses organic substrates to produce carbon needed for their growth and development. They derive their energy from oxidation and reduction of organic substances. The use the reduced carbon produced by autrotophs as as source of electrons, carbon and energy. Example is fungi that uses carbon as electron donor and source for carbon and energy.
I think most scientists would not respect this researchers claim.
It doesn't seem like the researcher followed the steps of the scientific method.
1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.
Publishing his/her work would be the very last step after completing everything else.
Answer: The correct answer is B) Frameshift mutation.
The given mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.
This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.
On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
