creation of PCR-based tests for many genetic diseases

Explanation:

Human genome project was an interanational project to study human's DNA; more specifically the base pairs (A, T, G, C) for protein coding genes. It was started in 1990 and completed in 2003. The direct outcome of the project was the discovery of at least 20,000 genes that encodes for proteins. Further, the base information helped establish polymerase chain reaction (PCR) based diagnostic tests for identification of genetic diseases. These genetic diseases are often studied via single nucleotide polymorphism (SNPs).

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

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
