Answer:
Alfred Russel Wallace was born in 1823 in Wales. He has been variously described as a naturalist, a geographer, and a social critic. He even chimed in on the debate over whether life could exist on Mars. His work on the theory of natural selection, however, is what he is best known for. During the second half of the nineteenth century, he became a public figure in England, known for his courageous views on scientific, social, and spiritualist subjects. His formulation of the theory of evolution by natural selection, which predated Charles Darwin's published contributions, is his most notable legacy, but it was only one of many contentious issues he studied and wrote about during his lifetime.
Vestigial traits are adaptations to environmental pressures which are no longer present.
homologous structures are similar structures found in different species that were present in a common ancestor.
analogous traits are similar traits found in different species that were developed independently (this process is known as convergent evolution)
I believe it would also be noting the color of a solution when heated.
Reduce can be lowering the amount of waste produced.
Reuse can be using materials repeatedly.
Recycle can be using materials to make new products.

Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
