Draw a representative observation of a stem and/or leaves from each group, as well as any evidence of sexual reproduction (i. e., spore production), if present. Describe how you used your observations to determine that your specimen is a lycophyte, horsetail, or fern (i. e., what features from your drawing allow you to differentiate between these three groups

Describe how a non-resistant staphylococcus aureus bacterium can produce a bacterium that is resistant to methicillin

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?

Si units are the modern form of the
