How will the properties of a biological membrane change if the fatty acid tails of the phospholipids are converted from saturate

kumpel [21]

Some of the properties that will change as the biological membrane composed primarily of phospholipids change from the saturated to unsaturated fatty acid tails of the phospholipid would include, permeability of the membrane, this will cause the membrane to be more fluid and not remain as controlling of the materials. The membrane will ultimately become poor in regulating ions and other materials from coming into the cell, as the phospholipids are not tightly packed due to them being unsaturated and having carbon double bonds within them. This can also affect the overall shape of the plasma membrane as well, causing it to be not as structured, and more fluid,

Crystals are made using supersaturated solutions of solids in water. These solutions hold more of the solute than they would at

Rudik [331]

Solubility controls the formation of crystals by the mechanism of oversaturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.

Crystals are solid structures where there is a fixed spatial arrangement of the molecules, there are many preparation methods, a very practical method and obtaining good crystals is from supersaturated solutions.

Solubility is the mechanism by which a supersaturated solution is formed, for this it is used that the water when heated has more energy and manages to dissolve a greater amount of solute, therefore by decreasing the temperature and consequently reducing the solubility the solution is over saturated.

When introducing some means of disturbance in the solution, the excess of solute is deposited in the form of crystals of excellent quality, this growth method is called hydrothermal synthesis

To achieve controlled supersaturation and crystals the temperature must be controlled precisely, to allow the formation of the crystals.

In conclusion, solubility controls the formation of crystals by the mechanism of over saturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.

How was Bohr's atomic model different from those of previous scientists?

Anestetic [448]

Answer:

Bohr placed the electrons in distinct energy levels. Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantized orbits. Also, rutherfords was just a hypothesis while Bhor took the time to make his an experiment

Does a bottle of acetic acid contain a solid or a liquid on a chilly morning with the window open and the laboratory at 10 ∘ C ?

Fofino [41]

Answer is: a bottle of acetic acid contains a solid.

Acetic or ethanoic acid (CH₃COOH) when undiluted is called glacial acetic acid.

Glacial acetic acid has freezing point (melting point) around 16.6°C, so it will be at solit state.

Vinegar is mixture of acetic acid (CH₃COOH) and water (H₂O). Vinegar is colourless liquid with sour taste and pungent smell, freezing point of the vinegar is lower than glacial acetic acid.

Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).

Balanced chemical reaction (dissociation):

CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
