Glycophosphatidylehanolamine anchors O All of the other are correct O Glycophosphatidylinositol anchors O Glycophosphatidylcholine anchorshat can scientists learn about ion channels from studying them using the patch-clamp method? O That channels switches back and forth between open &closed conformations O all of these O What particular conditions will tend to open a channel OWhich ion can pass through a particular channelO Solute O Solute Explain if water will flow into or out of the cell in the following scenarios: 1. Salt is 30% inside the cell and 35% outside the cell. Water is % inside the cell % outside the cell Water will flow [inside / outside] so the cell can reach equilibrium.
- Why does osmosis seem backwards from other forms of diffusion? O Science has still not been able to explain this strange behavior of water. O Hydrogen bonding between water molecules prevents them from diffusing the same way that other substances do. O Water is so important to life that it has an exemption from the normal rules. O Osmosis only seems backwards, but it's really not. It's actually just the diffusion of water molecules down their concentration gradient, which is inverse to the solute's concentration gradient. O Because osmosis is actually a completely different process than diffusion, and involves active transport.Proteoglycan aggregates in tissues form hydrated, viscousgels.

- the game. And the game officially started! The game will work by team. Sakuragi and his team are placed in small submarine shrunk down to microscopic size and injected into a stained living ceili. The teams goai is to find out what is happening in the area because the object is slowly occupying the space where there are many creatures are living. They started their path on the fluid. As they continue their journey, they reached in a transparent layer. In order to make the navigational adjustment, 1. they need to identify this substance. What could be this thing? They scanned the area using an ultra telescope designed by the company that useful for their goal. Upon using the tool they have found out that it contains a wide variety of biological molecules magnification micro 2 There are polar and non - polar region. What are these biomolecules? They tried to get insideCholera is a disease caused by bacteria that make cholera toxin. In the presence of this toxin, chloride ion channels in cells of the small intestine lining are stuck in their open position. As a result, an excess of chloride ions (Cl) flows from these cells into the lumen of the small intestine. Movement of Cl creates a charge gradient, so sodium ions (Na+) also flow into the lumen. Explain why the movement of these ions into the lumen results in the life-threatening diarrhea that characterizes cholera.Electronegativity is the ability for an atom or molecule to attract electrons (see chapter 2). Considering the components of theelectron-transport chain, with protein I being the beginning of the chain and protein IV the end of the chain, which end has thehigher electronegativity?
