What most likely led to a change in the widely accepted theory of evolution? new experiments involving genes and evolution exper
ss7ja [257]

Incomplete question. Full question reads;

Darwin developed the theory of evolution to explain why there are so many different kinds of living things. He could easily observe that offspring of any animals were slightly different from their parents and that this could allow for big changes over thousands of years. He did not know that genes caused the differences. Genes are now very important in the modern theory of evolution.

What most likely led to a change in the widely accepted theory of evolution?

Answer:

<u>new experiments involving genes and evolution </u>

<u>Explanation:</u>

Indeed, the original theory of evolution has experienced several changes in its acceptance because of its imperfect and wrong assumptions not based on generally acceptable scientific facts,

Hence, new experiments involving genes and evolution has led to a change (disagreements and few agreements) in the widely accepted theory of evolution.

How many degrees of unsaturation are lost or gained in the base-induced transformation from mito-ph to its photoactive ring-open
Fudgin [204]

Unsaturation (IHD) 2 hydrogen Needed

IHD = [(2n+2) -H]/2
(H: X=1, N=-1, O= zero)

Unsaturation:
Double bonds = 1
Rings = 1
Triple Bonds = 2

The degrees of unsaturation in a molecule are additive — a molecule with one double bond has one degree of unsaturation, a molecule with two double bonds has two degrees of unsaturation, and so forth.
