in a chemical reaction a metal will become?
a cation lose an electron
***which correctly describes ion Al -27 ele charge -3 mass 14 elect charge +3 mass 24
Electric charge +3 WHY? mass is 26.9, so the 27 is the mass it is in the group 3A (normally 3 valence electrons) **the negative sign shows it as losing an electron, therefore it is a cation, therefore positive

% * whole = part change to decimal 15% = .15 SUBRACT .15 from 100 (since it is OFF not OF) = .85 .85 * whole = 102.00 now we can divide $102.00 by .85 = $120.00

Subject and Object differences
If I say, "I love you," YOU are the object of my affection, and you is also the OBJECT of the sentence (because I am loving you, making ME THE SUBJECT and you the object). I love you. You are the object of my affection and my sentence.
when to use WHO and WHOM
Like WHOM, the pronoun HIM ends with m. When you're trying to decide whether to use who or whom, ask yourself if the answer to the question would be HE OR HIM. That's the trick: if you can answer the question being asked with him, then use whom, and it's easy to remember because they both end with m.
"Who (or whom) do you love?"
The answer would be "I love him." Him ends with an m, so you know to use whom.
"Who (or whom) stepped on Squiggly?"
the answer would be "He stepped on Squiggly." There's no m, so you know to use who.
affect vs effect
First, the mnemonic involves a very easy noun to help you remember: aardvark. Yes, if you can remember aardvark -- a very easy noun -- you'll always remember that affect with an a is a verb and effect with an e is a noun. Why? Because the first letters of "a very easy noun" are the same first letters as "affect verb effect noun!" That's a very easy noun. Affect (with an a) verb effect (with an e) noun. "But why Aardvark?" you ask. Because there's also an example to help you remember. It's "The arrows affected Aardvark. The effect was eye-popping."

smell The olfactory nerve is actually a collection of sensory nerve rootlets that extend down from the olfactory bulb and pass through the many openings of the cribriform plate in the ethmoid bone. These specialized sensory receptive parts of the olfactory nerve are then located in the olfactory mucosa of the upper parts of the nasal cavity. During breathing air molecules attach to the olfactory mucosa and stimulate the olfactory receptors of cranial nerve I and electrical activity is transduced into the olfactory bulb. Olfactory bulb cells then transmit electrical activity to other parts of the central nervous system via the olfactory tract. AFFERENT- move sensory info toward the brain
vision The optic nerve has only a special sensory component Special sensory conveys visual information from the retina (special afferent). Visual information enters the eye in the form of photons of light which are converted to electrical signals in the retina. These signals are carried via the optic nerves, chiasm, and tract to the lateral geniculate nucleus of each thalamus and then to the visual centers of the brain for interpretation.
III Oculomotor ..
eyelid and eyeball movement Consists of two components with distinct functions: A. Somatic motor (general somatic efferent) Supplies four of the six extraocular muscles of the eye and the levator palpebrae superioris muscle of the upper eyelid. The somatic motor component of CN III plays a major role in controlling the muscles responsible for the precise movement of the eyes for visual tracking or fixation on an object. B. Visceral motor (general visceral efferent) Parasympathetic innervation of the constrictor pupillae and ciliary muscles. The visceral motor component is involved in the pupillary light and accomodation reflexes.
Primarily excretory important role in regulation of homeostasis: Principle organ of regulation of Extracellular fluid volume & Electrolyte composition Major Site of Hormone Synthesis Primarily those regulating systemic metabolic function Erythropoietin 1,25-diOH vitamin D Renin Vasoactive prostanoids and kinins

innervates superior oblique turns eye downward and laterally The trochlear nerve is purely a motor nerve and is the only cranial nerve to exit the brain dorsally. The trochlear nerve supplies one muscle: the superior oblique. The cell bodies that originate the fourth cranial nerve are located in ventral part of the brainstem in the trochlear nucleus. The trochlear nucleus gives rise to nerves that cross (decussate) to the other side of the brainstem just prior to exiting the brainstem. Thus, each superior oblique muscle is supplied by nerve fibers from the trochlear nucleus of the opposite side. The trochlear nerve fibers curve forward and enter the dura mater at the angle between the free and attached border of the tentorium cerebelli. The nerve travels in the lateral wall of the cavernous sinus and then enters the orbit via the superior orbital fissure. The nerve travels medially and diagonally across the levator palpebrae superioris and superior rectus muscle to innervate the superior oblique muscle.
chewing, face & mouth touch & pain The trochlear nerve has only a somatic motor component: Somatic motor (general somatic efferent) Somatic motor innervates the superior oblique muscle of the contralateral orbit. The superior oblique muscle is one of the six extraocular muscles responsible for the precise movement of the eye for visual tracking or fixation on an object.
