6x10-3M that will be your answer muh friend yes i know i know im big brain
Answer:
I > III > II
Explanation:
I) A disulfide bond between two cystines is created when a sulfur atom from one cystine forms a strong, single covalent bond with a sulfur atom from a second cystine. When a disulfide bond is created, each cystine loses one hydrogen atom. The atom count is 11 for a cystine in mid-chain, but changes to 10 if the cystine joins with another in a disulfide bond. This lead to a much more stable intermolecular interaction.
III) Hydrogen Bonding in water
These hydrogen bonds are at best an interaction, inducing slight positive and negative charges in the Hydrogen and Oxygen/Nitrogen atoms.
The Hydrophilic amino acids have O & N atoms, which form hydrogen bonds with water. These atoms have an uneven distribution of electrons, creating a polar molecule that can interact and form hydrogen bonds with water.
The hydrogen bonds aren't as strong as the covalent bonds in disulfides.
II) Hydrophobic interactions between two leucines
A hydrophobic interaction is formed between two nonpolar molecules.
It describes the preference of nonpolar molecular surfaces to interact with other nonpolar molecular surfaces, thereby displacing water molecules from the interacting surfaces.
Answer:
Boiling/melting point
Explanation:
Some elements can’t handle the heat nor the cold, so they separate like oil & water.
What is diffusion?
The diffusion of substances within a solution tends to move those substances <u>down</u> their <u>concentration</u> gradient.
Aim of diffusion:
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells. Until the concentration is the same everywhere, the molecules travel from a location of higher concentration to a region of lower concentration.
Diffusion occurs in gases and liquids because random molecular movement is possible.
Types of diffusion:
Simple diffusion and facilitated diffusion are the two primary categories of diffusion.
- Simple diffusion: An action where the substance passes across a semipermeable barrier or solution without the aid of transport proteins. For instance, bacteria use simple diffusion to transport minute nutrients, water, and oxygen into the cytoplasm.
- Facilitated diffusion: It is the passive transfer of molecules from the area of higher concentration to the area of lower concentration across the cell membrane using a carrier molecule.
The main aim of diffusion is to arrive at an equilibrium state. When the amount of the particles is uniformly distributed or constant throughout a solution, it is said to be in equilibrium.
