Answer:
Ribonucleotides (RNA) and deoxyribonucleotides (DNA). See more details below, please.
Explanation:
Ribonucleotides are the nucleotides of the RNA (they have pentose, ribose and nitrogenous base, except for Thymine; they contain uracil). Deoxyribonucleotides are the nucleotides of DNA (they have pentose, deoxyribose and nitrogenous base, they have Thymine).
<span>The answer would be: C)Play loud music at precisely 2:30 in the afternoon for two weeks.
All other option is involving an action at 10.30 AM </span>which the only times 'The Magic Donkey' is aired on the television. If Roger wants to prove the hypothesis, he should do the experiment when <span> 'The Magic Donkey' is aired, not before or after it.</span>
Answer:
50%
Explanation:
DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.
However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).
Answer:
I've got no idea what you're asking but my guess would probably be. . . C?
Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
a video that shows a large river that has penguin populations on both sides
a video that shows penguin species that have different mating dances a video that shows
a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean
Answer:
The right option is a video that shows penguin species that have different mating dances.
Explanation:
Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
