A
<u>Individual lipid molecules are free to diffuse laterally in the surface of the bilayer</u> is a general feature of the lipid bilayer in all biological membranes
Explanation:
The inside of the bilipid layer of the cell membrane of cells is made of fatty acid chains and cholesterol which are nonpolar molecules. they are sandwiched between the polar (glycerol) ends of the chains because they are hydrophobic and cannot interact with the ‘watery’ extracellular fluids. Non-polar molecules like lipids can easily diffuse laterally, within this lipid layers of the membrane because non-polar molecules interact well with other nonpolar molecules.

Answer:
4.68x10⁻⁵N
Explanation:
The pH is defined as -log [H⁺]. If an acid has a pH of 4.33, [H⁺] is:
pH = -log [H⁺]
4.33 = -log [H⁺]
10^(-4.33) = [H⁺]
4.68x10⁻⁵M = [H⁺]
The [H⁺] is in molarity units, that is mole / L. Normality has as units equivalent / L. As the equivalent in an acid-base reaction is defined as the number of moles of H⁺, in this case:
4.68x10⁻⁵M = <em>4.68x10⁻⁵N</em>
Magnified we see that the carbon atom VIBRATE in place.
When microscope is used to view the carbon atom at the atomic level, it was discovered that the atom vibrate in place. Each individual atom is spherical and have fuzzed edges.
I think the correct answer from the choices listed above is the second option. If a mixture of two metals was separated based on one metal's ability to allow electricity to pass, then the property that was important would be conductivity. <span> It is the ability to conduct electricity.</span>
Answer:
Ni^2+
Explanation:
The following data were obtained from the question:
Proton = 28
Electron = 26
Neutron = 34
Next, we shall determine the atomic number of the element.
Atomic number of an element is simply defined as the number of protons in the atom of an element.
Thus,
Atomic number = proton number
Proton = 28
Atomic number = proton number = 28
Atomic number = 28
Therefore, the element is Nickel since no two elements have the same atomic number.
Finally, we shall determine the charge on the Nickel atom as follow:
Proton = 28
Electron = 26
Charge on atom =
Charge on atom = Proton – Electron
Charge on atom = 28 – 26
Charge on atom = +2
Therefore, we can represent the Particle as Ni^2+
