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.
A systolic pressure of 112mmhg is a representation of the pressure in arteries during the contraction of the ventricles in the heart. So, C is correct. Systole means contraction while diastole means rest.
Given what we know about the correlation between the liver temperature of a corpse and the estimated TOD, we can conclude that the estimated time of death is approximately 10:30 pm of the night before.
<h3>How do we estimate the TOD?</h3>
- This can be achieved using a mathematical formula.
- The formula in question involves taking the normal body temperature of a living human and subtracting the liver temperature of the body.
- The remaining is the difference in temperature.
- Given that a body will lose roughly 1.5 degrees worth of heat per hour, we divide the remaining number by this to get the amount of hours since the death.
- This leads us to the conclusion that this individual perished roughly 15.5 hours earlier.
Therefore, given the way in which we use the correlation between liver temperature and time to analyze and approximate a time of death, we can confirm that this individual will have perished at roughly 10:30 pm of the night before.

a sinoatrial node is the main pacemaker that begins each heartbeat located in the junctions of superior vena cava and the right atrium. It signals from the node that spread through the atria and determines the heart rates.
