The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - Correct answer-true In your own multicellular body, cells with different functions have different DNA. - Correct answer-false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - Correct answer-true The paramec...

ASU BIO 181 Exam 2 Questions and Answers 2023 Specifically in a cell where does Glycolysis occur? Cytoplasm T/F The cell does not need ATP to survive. False Where is carbon dioxide produced? Mitochondrial matrix T/F The citric acid/Kreb's cycle breaks down carbohydrates into CO2. True T/F FADH2 results as one of the products of the citric acid cycle. True Specifically where in a cell does the citric acid/Kreb's cycle occur? Mitochondrial Matrix ...

The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: correct answer: kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. correct answer: true In your own multicellular body, cells with different functions have different DNA. correct answer: false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. correct answer: true The par...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...

Write a few sentences that explain what limits an individual cell from becoming more complex. - Correct answer-Bimolecular machinery and division of labor The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-Kidney In cell Biology what can limit the progress of science? - Correct answer-Technology True or False: In you own multicellular body, cells with different functions have different DNA - Corre...

Excitatory synapses make the post-synaptic cell less likely to fire. - ANSWER-False The neural tissues are: - ANSWER-Spinal cord, sensory neurons, and brain How do the glial cells (i.e., myelin sheath) speed up the firing of neurons? - ANSWER-The cell wraps extensions of a fatty insulating substance (myelin) around the axons of neurons. The action potential is: - ANSWER-A result of the movement of ions. Receptors are made from membrane-bound polyribosomes. - ANSWER-True List the 4...

Bio 181 ASU Exam 3 Questions with complete solutions List the 4 types of glial cells and list a phrase to describe their function. - answer1. Schwann cells wrap around the axon of a cell in the PNS, while providing electrical insulation. 2. Oligodendrocytes do the same thing as Schwann cells but they do it in the CNS. 3. Astrocytes protect the brain from toxic chemicals. 4. Microgilia protect the brain. T/F When the presynaptic cells contacts a muscle cell, the synapse area is called a mo...
