Apoptosis - correct answer-Cells of a neoplasm do not die off like normal cells so the number of cells grows, rather than remain constant as in healthy tissue. Labile Cell - correct answer-Cells of tissue that continuously divide and replicate throughout life. Ex: epithelial cells of skin, oral cavity, vagina, cervix, GI tract, and bone marrow. Permanent Cell - correct answer-Cells of tissue that do not proliferate. Ex: nerve cells, skeletal muscle cells, and cardiac muscle cells. Stabl...

four major classes in the molecules of life - 1. Lipids 2. Carbohydrates 3. Proteins 4. Nucleic Acids monomers - "building block" molecules of a polymer polymers - many monomers covalently linked together dehydration - how polymers are synthesized hydrolysis - how polymers are broken homopolymers - polymers composed of identical monomers heteropolymers - polymers composed of different monomers carbohydrates - energy storage - glycogen in human starch in plants carb...
