HEL 30 point Some scientists have suggested that the Protista kingdom should be split into several groups instead of remaining as one group. Which of the following provides the best argument for dividing up the Protista?

1: Sporozoan Protista are more similar to the Fungi than they are to any of the other groups of Protista.

2: Colonial Protista have much more in common with other multicellular organisms than they do with unicellular Protista.

3: The Protista that have nuclei are significantly different from the rest of the Protista that lack a nucleus.

4: Protista do not have specialized cells and have varying methods to obtain their food.

The seed coat's most important function is to provide a) a nonstressful environment for the megasporangium. b) the means for dispersal. c) dormancy. d) a nutrient supply for the embryo. e) desiccation resistance.

Hey me with this one❤❤❤❤ every organism needs food. does a cell also need it? explain very briefly.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
