I’m assuming you needed what part of the body it belongs too. Your questions isn’t very clear. But it belongs to the Excretory system
Answer: C.
Explanation
There are higher C-H bonds in lipids than in Carbohydrates.
These C-H bonds stored higher chemical potential energy effectively of thr amount (413 kj/mol.)
Carbohydrates has high C-O glycosidic bonds or linkages of ( 358 kj/mol) which stores low amount of energy compare to C-H bonds.
Futher more higher ATPS are produced during ELECTRON TRANSPORT CHAIN REACTION per molecules of tryglycerides metabolize compare to molecules of glucose because the longer chains of lipids ensures that more C-H bonds broken down ,ans therefore more oxidation to supply protons for ATPS synthesis from.proton pumps.
Your answer would be B. The reason is because the ears of any species of fox are used to keep cool, depending on the size of the fox's ears. In this case, the arctic fox is trying to stay warm, to the ears must be smaller in order to conserve heat. Hope this helps!
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
