A sympatric speciation can occur commonly in both animals and plants. Sympatric speciation events are very common in plants because it is normal for them to develop multiple sets of chromosomes.
II - False
Sympatric speciation occurs without geographic variation. When two populations of the same species live in the same area but there is no crossing between populations, sympatric speciation occurs.
III - True
Sympatric species may indeed lead to the formation of new species. Sympatric speciation is believed to be responsible, for example, for the large number of cichlid fish species found in Lake Victoria on the African continent. According to research, this lake was colonized by only one ancestral species.

<u>Trans fats</u> can elevate LDL cholesterol, increase triglycerides, and lower HDL cholesterol.
These fats have a significant result in raising blood cholesterol levels. It exist naturally in small quantity in some meat and dairy products.
The raised blood cholesterol levels are a risk factor for heart disease/attack. Triglycerides are the fat present in our bloodstream.
It is so because trans fatty acids have one or more double bonds present in trans configuration instead of the usual CIS configuration. Trans fats are unsaturated fats produced from vegetable oils. Therefore, trans fats are commonly used in the composition of margarine and commercially baked or fried foods.
