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.
Mutation. A mistake made while DNA copies which causes changes in DNA
D) On Sunday, Julia ran for three miles, causing a greater than average amount of perspiration and exhalation of water vapor.
The answer is letter D.) the components of a cell
Environmental science is an interdisciplinary field that studies the interactions of the environment. The component of a cell can be studied through the lens of biology and may not require addition disciplines.
