The diagram below shows the chemical structure of a type of lipid molecule called a phospholipid.
SVEN [57.7K]

Answer No 1:

Phospholipids are made up of phosphorus head and two fatty acid molecules.  These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.

Answer No 2:

The building blocks of lipids are glycerol and fatty acids.

Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.

Answer No 3:

Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:

  • Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
  • Lipids store energy and provide insulation to the body of an organism.

If all variation among individuals in a population is due to differing genotypes alone, heritability is _____, and the slope of
AVprozaik [17]

Answer:

<em>If all variation among individuals in a population is due to differing genotypes alone, heritability is 100%  and the slope of the line used to measure it is 1.</em>

Explanation:

If the genes play no role in the variation among organisms of a species, then the heritability will be zero percent. Hence, if all the variations among individuals of a population occur due to the differences in the genotype, hence the heritability will be 100%. This is because genes are the hereditary molecules and the genotype of an organism comprises of the different genes present in an organism.

Aspirin and other nonsteroidal anti-inflammatory drugs (NSAID)inhibit inflammation by inhibiting an enzyme in the prostaglandin
Drupady [299]

Answer:

Aspirin works by inhibiting the production of prostaglandins. Aspirin inhibits the formation of prostaglandins by combining with the COX enzymes. Prostaglandins function as messenger molecules to monitor different physiological procedures in distinct regions of the body. One of the prime activities of prostaglandins is to stimulate inflammation and pain.  

Prostaglandins are also the essential controller of platelet aggregation. By changing the COX enzymes inside the platelets, aspirin makes platelets to lose the stickiness, which is required to instigate clotting of blood.  

There are two forms of cyclooxygenase, that is, COX-1 and COX-2. COX-1 generates prostaglandins and COX-2 mediates pain and swelling in response to tissue injury. Aspirin prevents both COX-1 and COX-2 functioning, while COX-2 is the therapeutic target of the drug.  

However, it is the association of aspirin with COX-1 in the gastrointestinal tract, which results in the unwanted side effects of the drug. COX-1 is required to sustain a thick lining of the stomach. As aspirin inhibits the COX-1 enzyme, thus, the continuous use of the drug can result in the thinning of mucus, which safeguards the stomach from gastric juices.  

In such cases, stomach bleeding, ulcers, and in certain situations perforation of the stomach can take place. Therefore, aspirin exhibits both bad and good effects.
