Answers

The phospholipids molecules are made up of two fatty acid chain and one glycerol compound which is attached to a phosphate group. Phospholipids are divided into two distinct regions, the head and the tail regions. The head region is polar while the tail region is non-polar.
The phosphate group which is located at the head region of the phospholipid molecules causes the glycero head to become hydrophillic [water loving]. Thus, the phosphate group impact polarity property on the head region of the phospholipid molecules.

Answer from: dezmondpowell

Phosphate groups play a role in the hydrophilic nature of phospholipids so that phospholipids are good emulsifiers because they can be attracted to water or oil

Further explanation

Lipids are a group of compounds which are generally not soluble in water but dissolve in non-polar organic solvents such as ether

Lipids themselves are divided into two groups, namely hydrolyzed lipids, and non-hydrolyzed lipids

Hydrolyzed lipids, for example, such as fat, and phospholipids

While lipids that are not hydrolyzed are steroids

Phospholipids are esters of glycerol but not all the OH groups are replaced by fatty acids (carboxylic acids)

Only R1 and R2 are replaced by carboxylic acids while R3 is replaced by phosphoric acid and choline or ethanolamine both contain Nitrogen

Phospholipids themselves are amphiphilic because their tails are hydrophobic (afraid of water) and nonpolar while their heads are hydrophilic (like water) and polar

This phosphoric acid bond with Nitrogen (choline/ethanolamine) compounds makes phospholipids a good emulsifier because they can be attracted to water and also oil.

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
