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.

Answer:
the geosphere, atmosphere, hydrosphere and biosphere.
Four spheres are all independent parts of a system. The spheres interact with each other, and a change in one area can cause a change in another. Plants (biosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. The biosphere contains all the planet's living things.

Answer:
Severe flooding is caused by atmospheric conditions that lead to heavy rain or the rapid melting of snow and ice.
Explanation:
Answer:
The given characteristics can be shown by Enzymes.
Explanation:
- Enzymes are substances, mostly proteins, that helps in increasing the speed or rate of a biochemical reaction (conversion of substrate to product) by reducing the activation energy barrier of the reaction.
- The enzymes which are made up of proteins have an specific location or region inside them which is called the Active Site.
- The biochemical reaction occurs at this active site.
- The specific substrate molecule(s) comes and associated with the active site of the enzyme, mostly by means of non-covalent interactions.
- By means of amino acid side chains (which have a definite pKa) the exact environment (oxidising or reducing) required for the chemical reaction to occur is maintained by the enzyme at its active site.
- After associating with its substrate(s) the enzyme undergoes certain conformational changes in order to position the substrate(s) in the correct orientation such the biochemical reaction can occur.
- After the products are formed, the enzyme further undergoes some conformational changes to release them.
- Enzymes are similar to transport proteins because:
- When the concentration of substrates is far more than that of the available enzymes molecules, then the enzymes would get saturated with substrates, like the transport proteins.
- The enzymes are highly specific for their substrates like the transport proteins.
- The enzymes undergo conformational changes during the biochemical reaction like the transport proteins.
- Both the rate of enzymatic reaction and membrane transport is regulated by the cell.
Potential energy is stored in energy in an object or system and kinetic energy is when the object is in motion
