Answer:
D) Because it can share four electrons in covalent bond.
Explanation:
The correct option is Option D.
Because it can share four electrons in covalent bond.
All other are incorrect because,
A = it can share four electrons in ionic bond.
Carbon share its electron and form covalent bond. It can not form ionic bond.
B = Because it can share six electrons inmetallic bond.
It is also incorrect because metallic bond is only formed by the metals and also there are only 4 valance electrons in carbon not six.
Option C = Because it can share four electrons in hydrogen bonds.
It is also incorrect because carbon can not form hydrogen bonds.

Explanation:
In the given question the Mary has the acidosis that is the level of pH in the blood have dropped below 7.
It is also provided that the smell of her breath is fruity due to the accumulation of fruity smell molecules called ketones which could be the result of the ketosis. Ketosis occurs when the cellular respiration uses fat as a substrate instead of the carbohydrate. This shows Mary has a condition called ketoacidosis.

Thus, insulin is the correct answer.
Explanation: I think the way to do it is to just divide the biomass of the primary carnivores by the herbivores since they are the trophic levels right next to each other. Therefore, the efficiency of energy transfer is (2360/25900)*100%=9.112%. Hope that helped!
