Answer:
The DNA of an amphibian, such as a frog, is different from the DNA in a human because a frog's DNA contains a different number and sequence of nitrogenous bases (option A).
Explanation:
DNA is the molecule that contains all the genetic information of the different species of living beings, being a molecule that is present in all of them.
Although the DNA of all living beings has the same basic structure —four nitrogenous bases, a deoxyribose and a phosphate group— what makes the differences between species is the length of the DNA molecule and the different sequences of nitrogenous bases present in the molecule. It is for this reason that frog DNA is different from human DNA.
The other options are not correct because:
<em> B. There are no differences in the </em><u><em>phosphate groups</em></u><em> from one species to another.
</em>
<em> C. All DNA molecules </em><u><em>contain guanine and adenine</em></u><em>.
</em>
<em> D. </em><u><em>Hydrogen bonds</em></u><em> between nitrogenous bases depend on the amount of paired bases, but are not related to differences in DNA between species.</em>
Hi there. I believe the answer is True. Hope I helped.

Answer:
A is the correct answer
Explanation:
These structures may or may not have the same function
Answer:
The correct answer would be switch from lysogenic to lytic growth.
The two cycles of viral reproduction are: lysogenic cycle and lytic cycle.
In lysogenic cycle, the viral DNA gets incorporated into bacterial or host genome and is spread with host cell reproduction or division. The viral or bacteriophage genome is called as prophage.
However, factors such as UV radiations or other chemicals can result in lysogenic induction i.e. switching of lysogenic phase to lytic phase.
During this, the viral genome is excised from the bacterial genome and is replicated, transcribed and translated in order to produce and assemble the viral offspring.
The viral progeny is then released by bursting or lysis of the bacterial or host cell.
