mitosis

a) Which type of cell has many nuclei? Why would these cells need so many nuclei? b) Which type of cell is the smallest? What unique adaptation do these cells have? What is this cellular organelle used for? c) Which type of cell is the smallest? What unique adaptation do these cells have? What is this cellular organelle used for? d) Which type of cell has several long extensions? How do these structures relate to the function of these cells?

What is the difference between a chromosomes and a chromatids? a) there is no difference they are the same  b) chromatids is always one stand of dna chromosomes can be one or two strand depending on the phase of the cell cycle  c) chromatids is always two strands of dna chromosomes can be one or two stands depending on the phase of the cell cycle d) chromosomes are homologous chromatids are identical

Mitosis leads to ... A.)identical (or nearly identical) cells B.)four unique gametes C.)one cell with double the normal number of chromosomes D.)two genetically diverse cells

Imagine you are working in a lab and you examine an unknown cell only to discover it possesses gap junctions and microvilli. Based on those findings, what can you assume regarding its function(s)? O a) it specializes in intercellular communication O b) it can withstand mechanical stress c) it likely functions in absorption O d) A and C O e) B and C

Cytokinesis involves ... A.)division of the cytoplasm B.)a cleavage furrow (animals) or cell plate formation (plants) C.)the completion of the cell cycle D.)all of the above

The Amoeba, the paramecium, and the euglena ( These are unicellular Protozoans) produce electrical impulses that travel along their cell membrane. This is possible because they are specialized to use properties exhibited by all cells. These properties include ... A) Separation of the fluid environments inside and outside the cell B) Active transport of Na+ out of and K+ into the cell. C) Portal proteins that allow diffusion of Na+ and K+ back in to the cell D) Maintaining unequal Na+ and K+ concentrations on the two sides of the membrane. E) All of these are true Explain why

ir of chromosomes

.The stage of the cell cycle during which sister chromatids separate from one another is   a) mitosis b) the G1 phase c) the S phase d) the G2 phase  e) the G0 phase

If a cell that had two copies of each chromosome, but problems with the spindle caused the sister chromatids to remain attached to each other and to only one spindle pole, what cells would result? a)  cells with 2 copies of each chromosome and 2 copies of each chromosome b)  cells with 3 copies of each chromosome and 1 copy of each chromosome c)  cells with 6 copies of each chromosome and 2 copies of each chromosome d)  cells with 4 copies of each chromosome and 0 copies of each chromosome e)  cells with 1 copy of each chromosome and 1 copy of each chromosome
