The statement that provides evidence of the common ancestry of all life is near universality of the genetic code (option A).
<h3>What is the genetic code?</h3>
Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code has the following characteristics:
- The genetic code is universal i.e all known living organisms use the same genetic code.
- The genetic code is unambiguous i.e. each codon codes for just one amino acid (or start or stop)
- The genetic code is redundant i.e. most amino acids are encoded by more than one codon.
Therefore, the statement that provides evidence of the common ancestry of all life is near universality of the genetic code.

<u>Question</u>:
Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?
-
years of decay
- quantity of energy
- number of stable atoms
- amount of material that has not decayed
<u>Answer</u>:
"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”
<u>Explanation</u>:
The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.
The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over 
of the sample remained. In percentage it is 6.25%
Answer:
Explanation:
In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.
<span>Transport of the water from the roots to the leaves is driven through the vascular tissue called xylem. Water gets absorbed from the soil by osmosis and it must cross several cell layers (filtration system) before entering the xylem. The method used in the upward movement of water through the xylem is determined by the cohesion-tension theory (capilarity+transpiration). The transport is passive and it occures thanks to the primary force that creates the capillary action (adhesion between the water and the surface of the xylem and cohesion between individual water molecules) movement of water. Transpiration is also an important factor in the upward water movement. Transpiration in leaves creates tension (differential pressure) and because of this tension, water is being pulled up from the roots into the leaves.</span>
