CORRECTLY
covalent bond - correct answer <<<<<<<<<<<A chemical bond that involves sharing a pair of electrons
between atoms in a molecule between two non-metals
Ionic Bond - correct answer <<<<<<<<<<<Formed when one or more electrons are transferred from one
atom to another between an metal and non-metal
Metalic bond - correct answer <<<<<<<<<<<the chemical bonds that bind atoms together in a metal

Critical angle equation - correct answer <<<<<<<<<<<Sin c=1/refractive index
Refractive index equation - correct answer <<<<<<<<<<<Speed of light in a vacuum/Speed of light in the
medium = sin i/ sin r
What is an axon? - correct answer <<<<<<<<<<<the long threadlike part of a nerve cell along which
impulses are conducted from the cell body to other cells.
Nuerons - correct answer <<<<<<<<<<<a nerve cell; the basic building block of the nervous system
What is the palisade layer? - correct answer <<<<<<<<<<<A tissue made of elongated cells, each
containing hundreds of chloroplasts, and is the main site of photosynthesis.
