Which of the following answers describes the most direct consequence of tropomyosin binding to f-actin in muscle cells? a. the end of f-actin is stabilizedb. loss of actin-adp subunits from the (+) end is preventedc. myosin binding to f-actin is blockedd. atp hydrolysis by myosin is blockede. the movement of myosin towards the (+) end is blocked

A

Explanation:

The "-" end of F actin is stabilized. The myosin head bind to actin and makes the actin filament to slide

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.
