Identify true statements of cholesterol and its fluidity.1. Cholesterol decreases membrane fluidity in areas called rafts, which contain large amounts of sphingolipids and cholesterol.2. Cholesterol inhibits crystallization that would otherwise occur in membranes rich in unsaturated fatty acids.3. Cholesterol is generally buried in a bilayer, with its planar rings oriented toward the solvent and its hydroxyl group aligned with the fatty acid tails of the bilayer.4. Cholesterol increases membrane fluidity that otherwise contains mostly long chain saturated fatty acids.

Asap! ! who wants to me with my assignment : ) (especially with how i’m gonna draw out the example) you have explored some interesting, informative, and amusing examples of models. now it's time to get creative and make your own model. here is the requirement checklist for your model: ✔ model types can include drawings, diagrams, physical models, virtual simulations, or videos. ✔ models must be created by you, not something selected from an online or outside source. ✔ submit a presentation, picture, video, or screenshot of your model. ✔ submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. it is important that you are using science terminology and are accurate. now that you know how to create and submit your model, you will need to choose a topic for your model. choose one of the three topics listed below. select each topic for an overview. -conservation of mass -atomic theory -thermal energy

The twister and runaway train are two coasters at the same amusement park. both coasters start at the same height. the coaster for the twister is twice the mass of the coaster for the runaway train. which roller coaster has greater gravitational potential energy at the start of the ride?

In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al oxidizing agent = reducing agent =
