Answer:
Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.
Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.
Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.
The three mechanisms which regulate the heart are endocrine, cardiovascular and Sinoatrial nodes.
The endocrine system consists of the glands and hormones of the human body. The cardiovascular system is the organ system which is responsible for the circulation of the blood around the body and the oxygenation of the body's tissues. The sinoatrial node (SA node) generates the electrical impulses and is considered the natural pacemaker of the heart.
Answer:
because they have thicker walls
Explanation:
blood is punped our of the heart very fast which means it would need a blood vessel witch thick walls to withstand the pressure. thin walls would cause the blood vessle damage and may evwn break as it wouldn't be able to withstans the pressure.
Answer:
12. In our somatic (body) cells, we have 2N chromosomes, but in our sex cells (sperm & eggs), we have half the number of chromosomes, which is N chromosomes
