Reading quiz questions for week 2 of BIOL 220 (June 30 to July 3) For June 30 (47.1-47.3) Sensory neurons convert external stimuli into action potentials. This conversion process is called Transference Transduction – YES Translocation Transubstantiation Transpiration The bending of stereocilia on hair cells is involved in the detection of Magnetic fields Electrical fields Smells Light Pressure – YES A conformational change in the pigment retinal is involved in the detection of Magnetic fields Electrical fields Smells Light – YES Pressure Hundreds of different membrane-bound receptors are involved in the detection of Magnetic fields Electrical fields Smells – YES Light Pressure Iron deposits in birds’ beaks might be involved in the detection of Magnetic fields – YES Electrical fields Smells Light Pressure Reading quiz questions for week 2 of BIOL 220 (June 30 to July 3) For July 1 (46.4) The parasympathetic nervous system and the sympathetic nervous system are the two main divisions of the Central Nervous System (CNS) Afferent Peripheral Nervous System Efferent Peripheral Nervous System Somatic Nervous System Autonomic Nervous System – YES The occipital lobe, at the rear of the brain, is responsible for Hearing Vision – YES Controlling muscles Learning and memory Speech Major functions of the brain stem include Autonomic control of the heart and lungs – YES Coordination of complex motor patterns Memory Planning and decision-making Mathematical calculations The hypothesis that specific neurons store specific memories is supported by experiments in which Removing large sections of the brain impairs recall Stimulation of precise areas triggers specific flashback-like memories – YES Memory worsens following sleep deprivation Memory worsens following exhaustive exercise Certain visual cues trigger a sense of "déjà vu" In the context of learning, synaptic plasticity can be defined as A switch in the neurotransmitter released by the presynaptic neuron Pairs of neurons’ ability to change size and shape Changes in the nature or strength of the connection between presynaptic neurons and postsynaptic neurons - YES Migration of the presynaptic neuron so that it can connect to other neurons Reading quiz questions for week 2 of BIOL 220 (June 30 to July 3) For July 2 (48.1-48.2) A single muscle cell is also known as a(n) Muscle tissue Actinomycete Muscle fiber – YES Myofibril Sarcomere Which of these muscle proteins binds calcium? Actin Myoglobin Myosin Troponin – YES Tropomyosin Muscle contraction is triggered by calcium entering the cytoplasm. In skeletal muscles, where does the calcium come from? Outside the cell membrane mitochondria The sarcoplasmic reticulum – YES peroxisomes It is synthesized in the cytoplasm from carbon and water Which of the following is NOT present in both cardiac and skeletal muscle tissue? Intercalated discs – YES Multiple nuclei Striations Sarcomeres Actin and myosin T tubules are straws through which you drink tea Invaginations of the cell membrane – YES The endoplasmic reticulum in muscle cells Proteins that help chromosomes separate during mitosis Proteins rich in the amino acid threonine Reading quiz questions for week 2 of BIOL 220 (June 30 to July 3) For July 3 (45.5) In the fish circulatory system, Blood passes by the gills and then goes straight to the other tissues without returning to the heart first – YES The heart has 2 ventricles Circulation to the gills is a lower-pressure circuit than circulation to the body The heart has 2 atria In mammalian circulatory systems, oxygenated blood is returned to the heart via the Vena cava Aorta Pulmonary artery Pulmonary vein – YES In mammalian circulatory systems, the heart chamber that pumps blood out to the whole body is designated as the Left atrium Left ventricle – YES Right atrium Right ventricle Myocardium The delay in electrical conduction at the AV node is useful to the heart because it Prevents bradycardia Promotes tachycardia Lets the ventricles fill with blood before contracting – YES Avoids hyperpolarization of the ventricles A typical systemic diastolic blood pressure for a healthy human is 8 mm Hg 25 mmg Hg 70 mm Hg – YES 120 mm Hg 150 mm Hg
