Single-nucleotide polymorphisms (snps) can be detected by microarrays, which are wafer-like substrates to which millions of short stretches of dna are attached. A microarray consists of many different squares, each one containing a different sequence of single-stranded dna to which fluorescently labeled strands of dnas from patients with different snps can hybridize. If one square will hybridize with an snp having a c-g base pair at a particular site, and an adjacent square will hybridize with an snp having a t-a base pair at the same site, which of the genotypes will hybridize with both squares and make them fluoresce?.

Consider the last statement in the prompt: "people take such environmental factors into account in their choices when deciding where to live." do all people have a choice as to where they live? what factor plays a key role in this decision and may therefore play a large role in determining quality of life?

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
