I need to compare and contrast eukaryotic and prokaryotic cells; and prokaryotes/eukaryotes.
Bacterial cells are prokaryotic. Choose two structures of bacterial cells and explain how these structures allow bacteria to function as unicellular organisms. There are many examples of eukaryotic cells. Algae, Fungi, Plants, and Animals are all composed of eukaryotic cells. Some algae and fungi are unicellular organisms, b
Give 2 types of cells, prokaryotic and eukaryotic. Choose structures of bacterial cells and describe how they work
There are two main types of cells: prokaryotic and eukaryotic. 1. Bacterial cells are prokaryotic. Choose two structures of bacterial cells and explain how these structures allow bacteria to function as unicellular organisms. 2. There are many examples of eurkaryotic cells. Algae, Fungi, Plants, and Animals are a
Refute or support - Flies come from rotten meat because they always appear where there is meat rotting. Later Louis Pasteur confirmed the non-validity of theory of spontaneous generation.
1. What are prokaryotes and eukaryotes? List three (3) ways prokaryotes differ from eukaryotes. 2. Natural selection is essentially a two-step process, what are the two steps? Ideas and research are included.
Please help with the following problem. The maximum yield of ATP per molecule of glucose in eukaryotic cells varies from 36 to 38 ATP. In prokaryotic cells, the maximum yield is 38 ATP. Explain why the maximum yield in eukaryotes varies, and why this is not an issue in prokaryotic cells
Eukaryotic cells are more complex that prokaryotic cells. Describe briefly how eukaryotic cells might have evolved. Are there unicellular eukaryotic organisms on Earth today?
Prokaryotic and eukaryotic cells share many similar features, developed and fine-tuned through years of evolution. Interestingly, the majority of prokaryotic cells exist as simple unicellular organisms, and only on rare occasions can grow together in colonies or demonstrate any type of intercellular communication. Eukaryotic cel
Why does a solution of sugar and salt needed to be administered for a person that has cholera? Why can't a person just drink a solution of just salt or just sugar?
What are the differences between prokaryotic and eukaryotic cells? What are the differences between plant and animal cells

When phage λ is grown on a Tn10-containing E. coli host, rare phage that transduce tetracycline-resistance can be isolated. You isolate DNA from λ and from λ-tet and cut each with EcoRI and BamHI and see the following sized fragments on an agarose gel: Tn10 is 9kb long, with one EcoRI site 3.5kb from its left end (and the
