Answer:
Partial hydrogenation
Explanation:
Vegetable oils naturally contain cis fatty acids. These fatty acids have double bonds and the two H atoms are on the same side of bond, producing a kink in the structure.
Cis fatty acids are converted into trans fatty acids by the process of partial hydrogenation or vegetable shortening. Hydrogen is added to convert some of the double bonds into single bonds but all double bonds are not removed. However, the cis double bonds end up getting converted to trans double bonds. H atoms are now on the opposite sides of the double bond. This arrangement makes the kink disappear from the structure hence trans fat is structurally similar to saturated animal fat. It increases the longevity of fats and makes it solid at room temperature but also has many side effects like increasing bad LDL cholesterol in blood.
Answer:
They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.
Explanation:
<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.
They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.
They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.
Thus, the selected option is the correct answer.
