The diagram shows embryo development of four different animals. How is this evidence used to suggest that life changes over time? Illustration showing embryo development of fish, turtle, bird, human

The DNA of all these life forms begins exactly the same and then changes over time as it replicates to produce the organisms different traits.

Late-stage embryonic development illustrates how acquired characteristics have caused these species to become more differentiated over time.

These stages indicate that animals within a species must have changed over time.

Striking similarities at early developmental stages is evidence that they came from a common ancestor.

i think it is true in my reasonment ..

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

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.
