Research shows that teacher effectiveness is the single most important school-based factor in student success. Students who have highly effective teachers for three years in a row will score 50 percentile points higher on achievement tests than students who have less effective teachers three years in a row (Sanders & Rivers, 1996).
A cuticle /ËkjuËtÉªkÉl/ , or cuticula, is a term used for any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of cuticle are non-homologous, differing in their origin, structure, function, and chemical composition.
Though you may only think about your cuticles when you get a manicure, they're not just hanging out on your hands. They serve a purpose, and they need your TLC. Your cuticles are part of your skin. They sit atop your nails' growth matrix, which is the part of your nails that grows.Cuticles are there for a reason, like a barrier or a protection for the nail matrix, says Richard Scher, MD, a Cornell University dermatology professor.on't Cut Your Cuticles. Dermatologists say there's no good reason to cut the cuticles. Cutting them could open the door to infection or irritation. If you remove the cuticle, that space is wide open, and anything can get in there, Scher says.
