Peer review. This is the basis of much of the scientific method: repeatability.
egg whites
While it may seem daunting, a basic meringue is nothing more than a mixture of beaten egg whites and sugar.
Answer: (x+7)(x-7)
how to get answer:
x^2-49 rewrite as
x^2-7^2
use diff of perf squares: a^2-b^2=(a+b)(a-b)
(a=x, b=7)
fill in the formula of the parenthesis
(x+7)(x-7)
to check you answer is correct, you can foil the answer (x+7)(x-7)
One negative affect to selectively breeding dogs is that it brings discomfort for animals that have very exaggerated characteristics.
I believe the answer is that the turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pairs with another section of the same strand. Intrinsic termination of transcription in E.coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template.
