B is the correct answer because none of this that you put are testable.
Tortoises are larger on the islands, where there are less predators
Flinches are different colors depending on their diet yet they are still anatomically similar
Animals are different within species and mate all the way to the point where some must die
Answer:
All organisms have the same nucleotides
Explanation:
All organisms have DNA. DNA is made up of the nucleotides Guanine, Adenine, Thymine, and Cytosine, with Guanine pairing with Adenine, and Thymine pairing with Cytosine. The combinations of pairs in a sequence determine an organism's individual genes.
Answer: Fermentation
Explanation: Fermentation is the process that occurs when there is not enough oxygen in yeast cells for aerobic respiration. Fermentation is the process that converts sugars to acids, alcohol or gases.
All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.
mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.
tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly
rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes
RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.
