Which of the following characteristics are true about a typical peptide (amide) bond? the bond is planar. there is free rotation about the carbonyl carbon and nitrogen bond. there is substantial double-bond character to this bond. there is a net negative charge on nitrogen and net positive charge on oxygen.

Yasmin's teacher asks her to make a supersaturated saline solution. her teacher tells her that the solubility of the salt is 360 g/l at room temperature (25 °c). how can yasmin make a supersaturated saline solution? she can add 380 g of salt to 1 l of hot water (75 °c) and stir until all the salt dissolves. then, she can carefully cool the solution to room temperature (25 °c). she can add 360 g of salt to 1 l of room temperature water (25 °c) and stir the solution until all the salt dissolves. she can add 380 g of salt to 1 l of cold water (5 °c) and stir the solution until most of the salt dissolves. then, she can carefully heat the solution to room temperature (25 °c). she can add 380 g of salt to 1 l of room temperature water (25 °c) and let the solution sit for 24 hours, so the salt dissolves.

Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. how does this most likely affect photosynthesis? not enough sunlight is captured in these areas of the leaves. carbon dioxide cannot enter these areas of the leaves. too much glucose builds up in these areas of the leaves. oxygen cannot be released in these areas of the leaves.
