Bio 181 Lab Midterm Study guide (GCU) QUESTIONS WITH COMPLETE SOLUTIONS

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...

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...

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...
