principle of falsifiability - The principle that a scientific theory must make predictions that are specific enough to expose the theory to the possibility of disconfirmation; that is, the theory must predict not only what will happen but also what will not happen. phrenology - The now discredited theory that different brain areas account for specific character and personality traits, which can be "read" from bumps on the skull. structuralism - early psych approach that emphasized the ana...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...

water soluble hormones - single amino acid, epinephrine, norepinephrine, peptides which include antidiuretic hormone or ADH and oxytocin, proteins that include insulin and growth hormone hormone response - the response to a hormone depends on both the hormone and the target cell. various target cells respond differently to different hormones exocrine - exocrine glands secrete into ducts. the ducts carry the secretions to the target site or onto the surface of the body endocrine - endocrine...

What is the pattern component of a scientific theory? - • The pattern component is a statement that summarizes a series of observations about the natural world. The pattern component is about facts—about how things are in nature. What is the process component of a scientific theory? - • The process component is a mechanism that produces that pattern or set of observations. Define Evolution - Evolution refers to the gradual change in the characteristics of living organisms over succes...

End Rhyme & Internal Rhyme - The repetition of sounds at the ends of words Internal Rhyme- rhyme that occurs within the line of poetry Rhetoric - the art of using language effectively and persuasively Satire - A literary work that criticizes human misconduct and ridicules vices, stupidities, and follies. Hyperbole - exaggerated statements or claims not meant to be taken literally. Metaphor - A comparison without using like or as Alliteration - the occurrence of the same letter or sound at ...

viroid - infectious agent consisting of a small circular RNA molecule that lacks a protein coat. Thought to cause disease by interfering with the cell's normal path of gene expression Common features between PROK and EUK (9) - PM, genetic info (DNA), similar mechanisms for transcription/translation, shared metabolic pathways (glycolysis, TCA), ATP, photosynthesis mechanisms, protein synthesis, proteasomes, cytoskeletal filaments built of proteins similar to actin and tubulin What are the 3...

As in the interval between stimuli decreases, the depolarization needed to generate the second action potential a. increases b. stays the same c. decreases d. There is never a second action potential - a. increases What is the approximate concentration of K+ inside a typical cell (intracellular concentration)? a. 150 mM b. 5 mM c. 0 mM d. 15 mM - 150 mM What is the approximate concentration of K+ outside a typical cell (extracellular concentration)? a. 150 mM b. 5 mM c. 0 mM d. 15...

what is the driving force for blood flow? - pressure gradient how does the body increase the blood vessel radius? - smooth muscle relaxation what is blood measured in? - ml/min what has the greatest effect on blood flow? - blood vessel radius the diameter of the blood vessel is the same as - two times the radius of the blood vessel the opening of the blood vessel where the blood flows is called the... - lumen what do you think will happen to the flow rate if the radius is increased by 0.5 ...

What is the key variable in an isometric contraction of a skeletal muscle? - The length-tension relationship. Based on the unique arrangement of myosin and actin in skeletal muscle sarcomeres, explain why active force varies with changes in the muscle's resting length. - When the skeletal muscles resting length increases, there is more time for myosin bridges to return to their starting position. Note the dip in total force at a muscle length of 90 mm as compared to the total force at a mu...

Assuming the resting potential of a sensory neuron is -70mV, which of the following represents a depolarization? - change to -60mV What is the approximate concentration of K+ inside a typical cell? - 150mM What is the approximate concentration of Na+ inside a cell? - 5mM What is the approximate concentration of Na+ outside a cell? - 150mM What is the approximate concentration of K+ outside a typical cell? - 5mM A negative membrane potential was recorded when the tip of the microelectrode w...

What was the effect of adding Na+- K+ pumps to the simulated cell - Transport of the ions was faster The movement of sodium and potassium maintained by the Na+ - K+ pump requires ____________ and is ________ concentration gradient - ATP, against Sodium-potassium pump moves _______ sodium ions and ____________ potassium ions simultaneously - 3, 2 Lipid insoluble - Solutes that require active transport for movement might be too large to pass or might be At what concentration of ATP were th...

The neurotransmitter released into the synaptic gap reaches the target cell by - diffusion You have just observed that each action potential in a burst can trigger additional neurotransmitter release. If calcium ions are removed from the extracellular solution, what will happen to neurotransmitter release at the axon terminal? - there will be more neurotransmitter release The end of the axon where it contacts a target is called the - axon terminal Neurotransmitter is released into the synap...

What is the smallest subunit into which starch can be broken down? - Glucose (monosaccharide). During digestion, the chief cells of the stomach secrete _____________ , which is responsible for the digestion of protein. - pepsin Circle the correct underlined term: The liver / stomach produces pepsin which, in the presence of hydrochloric acid, digests protein. - stomach ________________ is a hydrolytic enzyme that breaks starch down to maltose. - Salivary amylase A ________________ is made...

Briefly describe the need for controls and give an example used in this activity. - controls are needed to validate the results of the experiment. tube 5 is an example where the enzyme that tests for contaminating glucose in the starch is absent What effect did boiling and freezing have on enzyme activity? Why? - the boiling denatured the enzyme and inactivated it as predicted. the freezing has no effect on the enzyme At what pH was the amylase most active? Describe the significance of this...
