Answer: 20.0g of Nitrogen is equivalent to 0.071394404106606 moles.
I hope this information is helpful!
Answer:
Statement D is incorrect
Statement E is inaccurate as it lacks completeness
Statement C is incorrect
Explanation:
In the case of statement D, it is deemed false because the functional groups present would be:
Acetone (not utilized as an energy source; it is eliminated from the body as waste), Betahydroxybutyrate, and acetoacetate (if they’re not oxidized for energy utilization).
For statement C being false, it is due to the fact that the increase in ketone body formation enhances with the presence of acetylcoA, yet acetone consistently appears in lower quantities since it's expelled by the body as waste, either through breathing (characteristic ketone breath) or in urine (ketonuria)
Regarding statement E, I find it incorrect because ketone bodies are produced chiefly in the liver and to a lesser degree in the kidney.
They are primarily formed in hepatic mitochondria, with lesser production in renal tissues
Among the options given in your question, the most appropriate answer is the second one, which is letter B.

A mutation affecting the HBB gene may result in the production of haemoglobin S (HbS), leading to sickle cell disease, thus classifying this mutation as harmful. Conversely, individuals who carry one copy of the mutant allele exhibit resistance to malaria, which renders this mutation beneficial. A mutation found in the EYC3 gene is regarded as neutral since changes in eye color can have beneficial or harmful outcomes. A mutation in the CFTR gene is deemed harmful, as it generates a malformed CFTR protein, disrupting the balance of Cl and fluids and causing mucus to thicken in various organs, ultimately impairing function. Furthermore, a mutation in the LRP5 gene leads to high bone mass and may result in various bone density-related conditions, categorizing this mutation as harmful.
Both kingdom plantae and plankton demonstrate similarities, as they both engage in the process of photosynthesis. These organisms offer oxygen and nourishment to other life forms, which in turn provides them with energy for survival. Additionally, both plankton and the members of kingdom plantae require nutrients for their growth and development. In terms of differences, plankton primarily inhabit water surfaces, while members of plantae are present on land and at the water surface. Certain species such as red and brown algae may also reside in deeper sea or ocean waters.
