What is different with retroviruses in reproduction is that they do not kill their hosts at first because they can still insert their own genome. This process is what is known the reverse transcription. This is done by different proteins.
Fossil fuels and green house gases which burn holes in the ozone layer of the atmosphere causing global warming
Answer:
A. Evolution
Explanation:
Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool.
Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.
So, the correct answer is A, evolution.
Answer:
Chromosomal non‐non disjunction resulting in extra sets of genes
