Explanation:
Animal fats and hydrogenated vegetable margarine contain saturated triglycerides. Saturated triglycerides are those that are made of saturated fatty acids. These saturated fatty acids are capable of forming atheroma (/plaques) along arterial walls, causing atherosclerosis or arteriosclerosis. These could both result in coronary thrombosis (blocking of a coronary artery by a clot of blood), and hence a myocardial infarction (heart attack).
Answer:
16
Explanation:
For a species with four pairs of chromosomes, 16 gametic combinations are possible.
This is calculated by using the formula 2n
A normal human has two pairs of chromosome which calculated by 2*2=4 to give the possible gametic combinations. However in the case of 4 pairs of chromosomes it is calculated by 2*2*2*2= 16 possible genetic combinations.
