Answer: Metal
Explanation:
Metals do not degrade with time as they are not biodegradable in nature. They are not degraded easily by the effect of bacteria and natural forces.
The metals are not degraded by the bacteria so easily and it is found preserved for many years.
The body gets degraded easily by the effect of bacteria on it and will be rotten and degraded after sometime. This does not affects the metal so it will be preserved even after many years.
Answer: Plants can use the energy from sunlight to turn water and carbon dioxide into. When the cell has enough organelles to make two cells, the division process starts.

Answer:
Antigen-presenting cells
Explanation:
Class II MHC molecules are present on the surface of all the antigen-presenting cells. Some of the examples of antigen-presenting cells (APCs) are dendritic cells, macrophages and B cells.
The Class -II MHC molecules are formed in the endoplasmic reticulum of these cells followed by binding of antigen peptide fragments to these class II MHC molecules. The antigen-MHC II complexes are then inserted into the plasma membrane of these antigen-presenting cells.
