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.
Various states of matter have molecules moving at different velocities.
<h3>Molecules in matter</h3>
Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.
Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.

<span>The amygdala is most used in times of fear, as well as for olfactory processing such as smell and pheromones, and emotional memory storage. It is located within the temporal lobes of the brain, where it receives sensory input and send signals to various parts of the brain including hypothalamus, the trigeminal nerve, and the ventral tegmental area.</span>
