Answer:
In the above experiment, these three flies are not enough cogent
Explanation:
Because in the above experiment which is designed to test that, in the above cage these three flies prefer which type of food either it is a banana which is fresh or either apple which is rotten. But the behavior of the flies is not the same, so it is difficult to judge where the flies spend more time. It is a probability that the flies spend most of the on a fresh banana or a rotten apple or both fruits.
These three flies could be unusual.
Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.
a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere
b) all organisms are descended from one or a few common ancestors
c) the genetic code readily evolves by natural selection
d) there's only one possible way to encode information in a macromolecule
Answer:
b) all organisms are descended from one or a few common ancestors
Explanation:
Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
