Usually, animal cells do not have vacuoles. But, when they do, those vacuoles are included in the processes of vesicular transport: exocytosis and endocytosis. Their role is to support that type of transport: vacuoles are storage vesicles for proteins and lipids that have to be containment, before their excretion (through the exocytosis). On the other hand, during endocytosis (materials brought into the cell) engulfed material is also located in that membrane-enclosed vacuole.
<span>The lysosomes are membrane-enclosed organelle, usually spherical. They contain a number of hydrolytic enzymes that are able to break down dfferent kind of molecules. However, to maintain the optimal conditions for enzymes to perform their function, pH in the lysosomes must bi acidic and thus maintained between 4.5 and 5.0. Apart from hydrolytic enzymes, the lysosomes contain substances involved in cell signaling and energy metabolism. </span>

Answer:
A) abandoned tires
Explanation:
Abandonded Tires are not a transboundary health hazard. Exposure to the vapors emitted by raw sewage can lead to gastroenteritis and E.Coli. Dead animal carcasses can carry several diseases that are detrimental or even deadly for humans. Hazardous substances may irritate the skin or eyes, make it difficult to breathe, and even cause cancer.
