The author claims that physically active people do not burn more calories than their less active counterparts. This suggests that at the cellular level, some changes have to occur in order to allow these 2 individuals to burn similar amounts of energy. Based on the glycolysis and cellular respiration concepts that you covered in BIO183 and in muscle physiology, what kind of adaptation do you think could be happening at the cellular level between these 2 individuals?

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
