The brain develops up to about 90% of its full maturation at about the age of five or six. It then takes about another 20 years to fully develop, or until most people are in their mid-twenties. And the last parts to develop are the frontal lobes, also known as the motor cortex. It is the part of the brain that is responsible for behavior.
Lipids tend to be hydrophobic, that is they "fear" water. they are soluble in oil or non-polar solvents
False
Polar solvents like water would be least soluble in lipids because lipids are nonpolar molecules. Lipids are hydrophobic, meaning they do not interact well with water. This is why lipids form structures such as cell membranes to separate their hydrophobic tails from water.
Lipids are soluble in Bloor's regent (Ethanol and Diethyl ether in 1:2 molar ratio).
True. Lipids are hydrophobic compounds that do not mix well with water.
That's correct. Lipids are typically not soluble in water due to their hydrophobic nature, meaning they repel water molecules. This is because lipids are composed of nonpolar molecules that do not form hydrogen bonds with water molecules.
Lipids are insoluble in water like glycerine.
Lipids are insoluble in water like glycerine.
No, distilled water does not contain lipids. Distilled water is water that has been purified through a process of heating and condensation, which removes impurities, including lipids. Lipids are nonpolar molecules that are not soluble in water.
Lipids are generally insoluble in water due to their hydrophobic nature, but they can be soluble in nonpolar solvents like ether or chloroform. Lipids can form micelles or bilayers in water to increase their solubility through hydrophobic interactions. The solubility of lipids can also depend on their structure and the specific interactions with the solvent molecules.
it has to be placed in alcohol first because lipids are soluble in alcohol but not in water.
No, T3 and T4 are not water soluble. They are lipophilic hormones, meaning they are soluble in lipids (fats) but not in water. This affects how they are transported in the bloodstream and how they interact with cells in the body.
