Suppose a farmer wishes to evaluate a new fertilizer. Her hypothesis is that the new fertilizer will be more effective that her current one, and will result in healthier, taller plants. She uses the new fertilizer on her corn field (Field 1), while using her current fertilizer on her soybean field (Field 2). Both fields are the same size, have the same type of soil, and get roughly the same amount of water and sunlight. After the growing season, the farmer notes that indeed, the corn crop in Field 1 seems to be healthier than the soybean crop in Field 2. She concludes that the new fertilizer is far superior than the old one. Was the farmer's experiment an effective test of her hypothesis

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone

When explaining dominant and recessive traits to a younger family member, they respond, "well chances are i can probably taste ptc, since dominant traits are more common." how might you address this misconception?
