Body is covered by ectoderm from out side of the body. Body is covered by endoderm from inside of the body. Both are attached to each other to give complete cover to the body.
Nope it's connective tissue

The endocrine system produces most of the hormones in the human body.
the most widespread cactus is prickly pear
The cells that line the epithelium in the tracheae are ciliated pseudostratified columnar epithelium cells.They are of three types -ciliated cellsgoblet cellsbasal cells

Calcium is the most prevalent in the human body.
depends on the type of epithelium. I'm assuming you are asking about stratified squamous epithelium as that is the most common type. It is found in areas of the body that are subjected to a lot of stress (environmental, mechanical) such as the skin, the anus, the oropharynx, and the vagina. Stratified columnar epithelium is found throughout the GI tract.

Water is the most common molecular subsance found in the human body(~98%). and phosphorous is the most abundant element in human body.
simple columnar epithelium
Yes. Calcium is the most metallic substance in the human body.
Ciliated epithelium is located in the lining of most body cavities. Some of the cavities that have ciliated epithelium are the lungs, trachea, and nose. Ciliated epithelium serves to keep dust and debris out of the lungs and control the flow of mucus.
