Observation correct answer: Gathering information, either through direct use of the senses or with the help of tools such as microscopes, thermometers, and balances that extend our senses. Can reveal valuable information about the natural world Hypothesis correct answer: Tentative answer to a well-framed question -- an explanation on trial. A rational account for a set of observations, based on the available data and guided by inductive reasoning. Hypothesis-Based Approach correct answer...

How "hypothesis based science" differs from 'discovery science" correct answer: -discovery science is making observations or document observations, making a conclusion, seeks science for natural causes. -Hypothesis-based is formal, using scientific method. List the criteria of a good hypothesis. correct answer: 1.First to find out the change of what you are testing 2.The hypothesis must be testable 3.It should be Falsifiable: there must be a possible negative answer. 4.Have inductiv...

What is a hypothesis? correct answer: - A tentative explanation thetas given and can be tested. - Predictions that can be tested by conducting observations or by performing experiments. What is a null hypothesis? correct answer: - Is a default assumption that an explanation or prediction is false. What is an alternative hypothesis? correct answer: - Is the alternative explanation to the null hypothesis thetas accepted as a best explanation if the null hypothesis is rejected. What is...

hypothesis correct answer: a well framed statement that can be tested, falsifiable, and replicated independent variable correct answer: The experimental factor that is manipulated; the variable whose effect is being studied. dependent variable correct answer: the variable that changes in response to manipulations of the independent variable. control group correct answer: the group that is not exposed to the treatment experimental group correct answer: the group that is exposed t...

Hypothesis correct answer: Tentative answer to a well framed question- an explanation on trial. Must be testable and falsifiable. Hypothesis must lead to prediction. It is a rational set of observations. Dependent variable correct answer: A factor that is measured in the experiment. Independent variable correct answer: Manipulated variable. Control group correct answer: Group controlled in the experiment Experimental group correct answer: Something that sets this group different...

ATP correct answer: (adenosine triphosphate) main energy source that cells use for most of their work Cancer correct answer: any malignant growth or tumor caused by abnormal and uncontrolled cell division Cell correct answer: (biology) the basic structural and functional unit of all organisms Cell theory correct answer: (biology) the theory that cells form the fundamental structural and functional units of all living organisms Cell wall correct answer: a thin membrane around the...

Receptors are made from membrane-bound polyribosomes. correct answer: True In the motor end plate, the event that is the immediate trigger for exocytosis is: correct answer: Calcium ions Draw a neuron, and label all the parts as described in lecture. correct answer: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal. correct answer: False Acetylcholine esterase breaks acetylcholine into muscarinic acid correct answer: Fal...
