Although vertebrate animals all look very different, they share the same basic structure of their skeleton and muscles. Some bones and muscles have been altered through adaptation for specific tasks, but they share the same evolutionary and genetic roots. The following
image highlights the same major area of the vertebrate skeleton in three different vertebrate animals: an allgator, a chimpanzee, and a
horse. This highlighting contains the in all three animals.

The answers are
a. Skull
b. Pelvic girdle
C. Pectoral girdle
D. Rib cage

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.

explanation:

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.
