The answer is 22.5 lb/gal.

The density of a liquid is quotient of mass and volume: D = m/V. The unit of the density is pound per gallon (lb/gal)

The density is unknown: D=?
But, we have:
mass: m= 90 lbs
volume: V = 4 gals

Do, the density of a liquid is:
D = 90 lbs / 4 gals
D = 22.5 lb/gal

tekilochka [14]

Answer:

<u>Option-</u>

  • As many believe after doing an extensive form of research work of years that reptiles are the ancestors of the mammals that we see now. Which means that we mammals evolved from the pre-historic form of reptiles.                                                                            

Explanation:

  • Fossils of Thrinaxodon, a species that lived during the Triassic period, have been found in both South Africa and Antarctica. Thrinaxodon had a reptile-like skeleton and laid eggs, but small depressions on the front of its skull suggest it had whiskers and, therefore, fur. Thrinaxodon may have been warm-blooded. The fossils of Thrinaxodon are consistent with the hypothesis that <u>mammals evolved from the pre-historic reptiles.</u>

Some viruses' capsid maybe enclosed with an envelope derived from the host cell (the cell that the virus is infecting), and this envelope is also derived from the host cell membrane.

The bond between CH2 and P of phosphate through O is called phosphoester bond. Only one such bond is present in both AMP and ADP.Link of phosphate groups through O by elimination of water molecule is called phosphoanhydride bond.In AMP, only single phosphate group present so no phosphoanhydride bond is present. But inADP, two phosphate groups are linked by one phospoanhydride bond.AMP  1  0ADP   1  1
