Every change in a species is coded within the DNA. But the bird had lost a toe an accident. So the toe-loosing-option isn't true because not every bird looses his toe.
(Example: If a women gets bitten by a snake on the arm and gets the arm removed from her body and then in a year or so has a baby with her new husband. The baby won't be born with one arm because his/her mother lost her arm.) <span />
When we breathe, our respiratory system takes up oxygen and carbon dioxide or other useless gases go out . The oxygen combines with the haemoglobin in the blood of the circulatory system . This is transferred to all the cells of our body to get energy.

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called <u>emulsification.</u>
<h3 /><h3>What is emulsification in the digestive system?</h3>
Fat emulsification is the process of increasing the surface area of fats in the small intestine by grouping them into small clusters. Large lipid globules are split up into a number of smaller lipid globules. In the chyme, these tiny globules are widely dispersed rather than aggregating into larger groups. Hydrophobic compounds include lipids. Bile salts, are present in bile and have both hydrophilic and hydrophobic sides.
Due to the fact that lipases can only effectively act on lipids when they are broken down into small aggregates, emulsification is crucial for the digestion of lipids. The lipids are converted into fatty acids and glycerides by lipases.
