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.
Naturally it will be very unstable. Likely cause bad weather or such
Answer:
developmental toxicity. im not sure though,

I think Number C is right because Since the organism eukaryotic we can safely assume that it is neither an archaea nor a bacteria since they are both prokaryotes. Secondly, since it can not photosynthesize, it can't be a plant because all plants can photosynthesize. The presence of a cell wall tells us that it can't be an animal cell since they lack cell walls. Therefore, the organism found is a fungus-like protist. Fungi are prokaryotic cells that are unable to photosynthesize and they have cell walls.
