Which of these is an example of pseudoscience a scientist wants to find the percent of teens that like the taste of brand x lemonade over brand y lemonade. she conducts a taste test of 500 teenagers she gives each team a bottle of lemonade with the label showing the brand of each lemonade. she asks each teenager to taste each brand after drinking water in between. she finds that 50% of teens like brand x and 50% like brand y lemonade. why are the results of the survey most likely unreliable

but there is no

i guess you forgot putting it.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
