Element: Simplest form of matter to have unique chemical properties. Atom: The smallest particles with unique chemical identities. Nucleus: Center of an atom (composed of protons and neutrons). Proton: Have a single positive charge (+1). Neutron: Have no charge. Electron: Tiny particles with a single negative charge and very low mass (-1)/determines chemical bonding properties of an atom. Atomic Number: Number of protons in the nucleus. Atomic Mass: Approximate number of protons and neutrons

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

Working in the field of education‚ I have encountered students who have learning disabilities‚ emotional problems that cause disruptive behaviors in the classroom‚ and student who show a lack of self-regulation. Knowing the complete history of the child will assist me with determining the types of interventions needed for the student. In addition‚ a complete history of the student will help with recommending services for the student. Understanding the parts of the brain and the functions of each

that have mapped the connections between neurons in the brain‚ gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus‚ in regulating appetite and metabolism‚ have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons.

If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It is composed of a thin‚ double-layered sheet of lipids‚ around the Cell and is a protective

Soc. 456 The Two Major Causes of the Urban Underclass Today in the United States‚ as well as in many other affluent‚ industrialized nations‚ there exists an urban underclass‚ which is defined as a class of people that comprises members of low-income households who have little or no participation in the workforce (Gilbert 2003‚ p. 274). Currently there are predominantly two distinct‚ conflicting views of why the underclass exists. On one hand‚ there is the notion that the underclass is simply
