Answer:
it is every organisms goal to "survive and repopulate" therefore, with natural selection the weaker organisms die because they did not possess the traits necessary to survive, and the strong survive and repopulate
Explanation:
<span>The first enzyme is reverse transcriptase. The concept of
reverse transcription was much unknown at first. A reverse transcriptase is an enzyme used to
generate complementary DNA (cDNA) from an RNA template, a process termed
reverse transcription. It is mainly associated with retroviruses. As it
contradicted the central dogma of molecular biology, which states that DNA is
convert into RNA, which is then translated into proteins.</span>
Answer:
Frogs do have gills as well as fully developed lungs which help them to survive both on land and underwater. On the other hand, tadpoles have chubby bodies, long tails and they do not look like a frog eventually in which they turn into. Their lungs take time to develop but once developed they too can live on land.
Explanation:
<em>The First one is 2, The answer to question 2 would be: Gene Splicing or Cloning</em>
<em>First, the gene that makes insulin is cut from human cells. After having the insulin gene, the scientist will put it inside bacteria so the bacteria will produce human insulin. This was called gene splicing. </em>
<em>Then the bacteria have insulin genes, the bacteria will be cloned to make multiple colonies of same bacteria. This phase called cloning. </em>
<em>and the last one 2, mitochondria.</em>
