Answer:
Biogeographic isolation is the separation of organisms of a species through geographical or biological forces.
Explanation:
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.
The following given statements are true of trans-fatty acids:
A. Often created by treating plant oils with hydrogen
D. Occur naturally in in food
<u>Explanation:</u>
The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.
Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.
Human body is made of ten different systems. All the systems require support and coordination of other systems to form a living and healthy human body. If any one of these systems is damaged, human body will become unstable and this lack of stability will ultimately lead to death. The instability caused by damage of one system cannot be stabilized by other systems because functions of one system cannot be performed by other systems. Knowledge of human body systems is very important for a medical professional because it is the base of all medical sciences and clinical practices. Although, generally, the structural aspects of human body systems are studied in anatomy and the functional aspects are studied in physiology but it is very important to have a coordination between the two subjects because knowledge of structure is incomplete without the knowledge of function and the knowledge of function is incomplete without the knowledge of structure.
