Without being able to see the actual slide - it can only be said for sure that sickle cell blood cells are deformed - it is visually apparent when viewed through a microscope - the deformity deters the blood cell from the cells intended optimal capacity to hold molecules (such as hemoglobin) and it makes it harder for the blood cell to travel efficiently through the body's arteries and veins.
A secure chemical landfill is a carefully engineered depression in the ground (or built on top of the ground, resembling a football stadium) into which wastes are put.

Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words,isotopes have the same atomic number because they are the sameelement but have a different atomic mass because they contain a different number of neutrons.
