When we think about internal stability we first think of animals. But all organisms must maintain internal stability or homeostasis. When plants are under water stress they respond in a way to conserve the internal water. How would leafy plants respond to temporary water stress? (A)Develop a thick waxy cuticle, (B)Leaves wilt and photosynthesis temporarily stops, (C)Stomata stay open to help draw water up from the roots of the plants, (D) Stomata open less frequently to restrict transpiration and conserve water.

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

One reason scientists are trying to develop fuel sources from corn and sugar is because these sources are renewable fossil fuels are being depleted these crops can be widely grown all of the above
