Answer:D. All of the above.
Answer:
polysaccharides are the genetic material
Explanation:
It can be concluded that through multiple experiments, such as those of Griffith and Avery, the first one observed the transformation when a destructive bacterial gene is transferred to a harmless one, it will modify it, the second one shows that DNA is not the only responsible for make this change happen, since I experiment with multiple substances, including degraded polysaccharides, finding that the latter were the ones that generated the change.
Answer:
d. Citric acid cycle
Explanation:
The only process in the list that requires the presence of O2 in order to occur is the Citric acid cycle or Krebs cycle. This cycle is part of the aerobic cellular respiration and it occurs only when O2 is available. If there is no oxygen, an alternative process that could happen is fermentation, but this is only carried by some microorganisms and some cells such as muscle cells.
In fact, oxygen is not needed by citric acid cycle but it is by the next step: the electron transport chain. In this chain, oxygen is the final acceptor of electrons, and without oxygen, the Krebs cycle doesn't occur because the final electron transport chain can't be done.
Answer:
d. all of the above are true.
