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.
Answer:
the fourth one. biomagnofication is when an organism ingests other plants or animals that have toxins in them. the toxins are widely distributed
Answer:
A a(birth rate+immigration)-(death rate)
Answer:
Photosynthesis is the process where green plants synthesis energy using the energy of the sun, carbon dioxide and water. Photosynthesis is very important to life it keeps most plants alive (autotrophs), and heterotrophs eat autotrophs to help them het energy. An autotroph is an organism that synthesis its own energy and heterotroph is an organism that gets it energy by digesting other organisms.
