number 1 is not part of the theory of evolution.
Evolution is change in the heritable characteristics of biological populations over successive generations.
First they don't use oxygen, plants use the CO2 in the air and release oxygen out into the air after the plant used up the CO2
The answer would be no. T-Tubules or Transverse tubules are
additions of the sarcolemma that infiltrate into the center of cardiac and
skeletal muscle cells. There would be no functional contraction since it
would not be capable to communicate or interconnect with the other cells.
Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
