Fossils give evidence upon organisms the past are not the same as those found and demonstrate a progression of evolution.
<span>The key points about cell theory are as follows:
1. All living organisms are made up of cells; the organisms may be unicellular or multi cellular.
2. The cell is the basic unit of life.
3. New cells are derived from pre-existing cells.
4. All cells maintain homeostasis.
Some new facts have been added to these basic facts; the new facts added include the following:
(A). Energy flow occur withing all living cells.
(B). Hereditary information derived from DNA is passed from cell to cell.
(C). All living cells are made up of the same basic chemical compositions.</span>
The answer would be D. variation

There
are three principles to keep in mind when predicting the sequence of
the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The
RNA polymerase reads the code from the template strand in the 3' to 5'
direction and thus produces the mRNA strand in the 5' to 3' direction.In
RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the
base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where
the first base is the coding base in the template strand of the DNA and
the second base is the base that is added to the growing mRNA strand.</span>
