When does the sign change in an inequality?When multiplying or dividing both sides with a negative number Number of solutionsone solution: x/y = a no solution: a = b infinite solutions: a = a What is slope intercept form? Identify what each variable means.y= mx + b m = slope (or "rate") b = y-int What is the formula for slope?y2-y1 / x2-x1 or rise/run Parallel Lines-same slope (different y-intercept) - do not intersect (unless they overlap completely) Perpendicular Lines...

How many Neurons (nerve cells) are in the brain? 87 billion - making up half the brain cells. How many glial cells are in the brain? 86 billion - making up half the brain cells. Neurons (nerve cells) excitable cells that transmit electrical signals Glial cells cells in the nervous system that support, nourish, and protect neurons CNS (central nervous system) brain and spinal cord PNS (peripheral nervous system) the sensory and motor neurons that connect the CNS to the rest of the body ...

4 step of neurotransmitters 1. Chemical must be synthesized in the nueron 2. When neuron is active chemical must be released and produce a response in some target 3. A response must be obtained when a chemical is placed on its target 4. A chemical must exist for removing the chemical from its site of action How is ACh synthesized? Use of enzyme "Choline acetyltransferase" Acetly CoA + Choline > enzyme > ACh How is ACh made? Acetyl CoA carries acetate to the transmitter systems i...

NeuropsychologyStudy of the relations between brain function and behavior Behavioral neurosciencestudy of the biological bases of behavior Stereotaxic appartatusSurgical instrument that permits the researcher to target a specific part of the brain AkinesiaSlowness or absence of movement Deep-brain stimu...

Cerebrum Major structure of the forebrain that consists of two virtually identical hemispheres (left and right) and is responsible for most conscious behavior. Hemisphere "Half a Sphere", referring to one side of the cerebrum. Brainstem Central structure of the brain responsible for most unconscious behavior. Cerebellum Major structure of the branstem specialized for coordination and learning skilled movements. In large-brained animals, the cerebellum may also have a role in coordinat...

Ion another name for a charged particle (when an atom loses or gains electrons) Ionic Bonding The strong force of attraction between positive metal ion and negative non-metal ion Covalent Bonding The strong force of attraction between positive nuclei and the shared pair of electrons Metallic Bonding The strong force of attraction between positive metal ions and the surrounding sea of free electrons Molecule atoms joined by covalent bonds Free (delocalised) electrons electrons that hav...

Prokaryotic cell Cell that does not have a nucleus or other membrane-bound organelles. Magnification The number of times larger an image is compared with the real size of the object Organelle specialized structure that performs important cellular functions within a eukaryotic cell. Resolution The ability to distinguish between objects that are close together. Nucleus A part of the cell containing DNA and RNA and responsible for growth and reproduction. Mitochondria ATP production

What is urinalysis? Measure the products excreted from the body via urine and can be used to detect many different diseases and chemical substances in the body. Through what method is the water leaving your body? (these are uncontrolled factors) -sweating -illness -exhalation -too much of salt what is the thing that monitors the level of water in blood? -the volume of water in the blood is monitored by hypothalamus in the brain why ion's level should kept in control? -ion level pre...

Are bacteria prokaryotes or eukaryotes? bacteria name an advantage of visible light microscope they can observe sub-cellular structures name a disadvantage of light microscope does not have a very high magnification or resolution name an advantage of electron microscope has a high resolution and magnification name a disadvantage of electron microscope they destroy the sample what is the function of the golgi apparatus?

What is a hypothesis? An Idea that you can test using practical experiments What are the Key features of a good hypothesis? A good Hypothesis must: Be able to be tested scientifically Relate one dependent variable to on independent variable What is a Null Hypothesis? States that there is no relationship or causality, for example, no relation between the temperature and the rate of reaction. What does qualitative data refer to? It refers to the appearance or value of something, such as t...
