Why is vitamin D necessary?
Vitamin D is required for calcium absorption from the small intestine
Muscle cells require an abundant amount of ATP to function. Therefore, muscle cells have numerous

Sodium ions are moving with their concentration gradient with the use of a protein channel across a plasma membrane. Determine the type of membrane transport used to transport these sodium ions.
What is facilitated diffusion?
Which of the following epithelia can be keratinized?
What is stratified squamous epithelium?
Connective tissues proper (or general connective tissues) produce collagen fibers using cells known as:
