<span>The propositions are:
A. The gas in the car is the digestive system that provides the necessary energy.
B. The frame of the car is the digestive system that provides structure and support to the body.
C. The exhaust system of the car is the excretory system that removes waste.
D. The engine of the car is the digestive system that circulates nutrients to the rest of the body.
E. The oil in the car is the excretory system that protects and coats the body.
The right answer is: C and D
*The exhaust system in the car removes waste from the engine like carbon dioxide, carbon monoxide, and several oxidated particles that are unuseful. The same thing for the excretory system in human, it excretes urea, creatinine, and urobillongen (all are wastes from a metabolism).
*The nutrient in the car are represented by the fuel, it is the component that gives energy to the wheels to roll.</span>

use the bioluminescence to attract mates for mating hence key in reproduction.
Therefore, beetles from different species should have different lighting
patterns so that they can only attract mates of the same species. This would
avoid interspecies mating which would probably involved expending energy in
produce nonviable offspring which is inefficient (hence will be unfavoured
natural selection). </span>
Answer:
Floodplains, alluvial fans, and mines.
Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.
