B each new layer has a new bit of the story to tell and you can see sequential time with each strata
A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.
2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA
D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals
C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
<span>A::T and G:::C is essential. The importance to the DNA structure is that prevents lose of genes and mis-formation of encoded products (protein and mRNA).</span>
Time-bound goals help provide a sense of urgency to the goal, a sense that it is important and needs to be completed. The uncertainty of business taints this ideal, however. so it is important that our goals should be time bound.
A physical change is basically a body change so like if a crayon is solid then sits in the sun for a long time it melts away that’s a physical change because it changes its physical appearance
