Answer: If it is almost impossible for a favorable trait to get passed down to offspring due to reproductive struggles, the species would not be able to undergo natural selection due to a lack in appearance of a trait.
Explanation:
If there are only two organisms with the adaptation, both of which lack any reproductive abilities, the odds of most of the species <em>not</em> dying out are very low. Only those two will have the adaptation and they rest will die out.

Answer:
Read Below
Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected
Answer:
B) Helicase uses energy from ATP Hydrolysis
Explanation:
Helicase's primary function is to separate the annealed nucleic acid strands. It is a motor protein and moves directionally along the phosphodiester backbone. It usually separates strands of double helix DNA or self annealed RNA. It used the energy from ATP hydrolysis and breaks hydrogen bonds between nucleotide bases.
In human body 95 types of helicases are found. They have sequence motifs required for ATP binding, ATP hydrolysis and translocation along nucleic acid phosphodiester backbone. The variable portion in their amino acid sequence imparts specific feature to each helicase.
ANSWER: compared to PH3 a PH1 would be more acidic than a PH3
Explanation: so on the PH scale 1 is acid 7 is neutral and 14 is alkaline. PH1 would be stomach acid, a PH3 would be vinegar.
