Answer:
But where is your diagram
Answer choices are:
A. Invalidate, because energy should not leave a closed system
B. Invalidate, because the amount of energy should stay constant
C. Validate, because an aquarium is an open system that loses and gains energy
D. Validate, because the amount of energy lost was replaced by matter.
The correct answer choice is:
C. Validate, because an aquarium is an open system that loses and gains energy.
Explanation:
As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.
Answer:
Air pollution is known to cause irritation in the eyes, lungs, nose, and throat. It creates respiratory problems and exacerbates existing conditions such as asthma and emphysema. When continually exposed to air pollution, humans become at higher risk for cardiovascular disease.

Polysaccharides are present in all living organisms where they carry out one or more of their diverse functions. While there is no specific category or definition of a complex polysaccharide, most are structurally complex. Polysaccharides contain 1–5 different monosaccharide (sugar) units. The different sugar units may have different anomeric configurations and/or be joined by different glycosidic linkages. Polysaccharides may be linear or branched. Branches may be short saccharide units on a linear backbone or the molecule may have a branch-on-branch structure; in either case, the branches may be isolated or clustered. Polysaccharides may contain non‐carbohydrate groups. Esters or cyclic acetal groups, when present, can be removed by appropriate treatments. All polysaccharides are polydisperse, i. e., are present in a range of molecular weights rather than having a single molecular weight
