A Cell __ a. is the smallest entity studied by biologists. b. may be a distinct entity, a building block of a more complex organism, or (as seen among a few extant species) alternating between these two extreme life styles representing, perhaps, an evolutionary link between them. c. All the statements including this one are correct. d. can be composed of many types of tissues. e. is found only in plants and animals. correct answer: Answer: b. may be a distinct entity, a buildin...

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 corr...

Division of Labor D. Find it's own food E. Nucleus correct answer: C. Division of labor The paramecium swims by way of using a flagella. correct answer: FALSE The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. correct answer: TRUE The paramecium dis...

What limits the paramecium from acquiring more complex functions? correct answer: number of Bio molecular machines T/F? The paramecium swims by way of using a flagella. correct answer: False The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: correct answer: Kidney T/F? A cancer cell will be anchorage-dependent for growth and immortal. correct answer: False Comparing a single-celled eukaryotic organism wi...

Water has which property or properties? correct answer: Hydrophilic Forms hydrogen bonds Ocean acidification is resulting due to correct answer: Global release of CO2 through the use of fossil fuels Which other element (besides Carbon) is often suggested a...

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...

The association of ribosomes with _____ invaginations would support the _____ theory. correct answer: membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is? correct answer: filapodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. correct answer: true T/F In an extant prok...
