We further find that the lines differ in the quantity and ratios of ascaroside molecules that they release.
The main differences between preparations are the character of the progesterones and the quantities and ratios of the steroids.
They have discovered not only molecules never before seen in comets, but have determined quantities and ratios of rare isotopes -- nuclear variations of elements -- that contain clues to the conditions that prevailed when the solar system was born.
It is based on the principle that explosives and other contraband contain various chemical elements such as H, C, N, O, etc. in quantities and ratios that differentiate them from other innocuous substances.
One-way ANOVA and Tukey's post hoc analysis were used to compare absolute quantities and ratios of (E -2-hexenal and (E -2-hexenal in malE -2-hexenaland nymphs and thE -2-octenal-oxo-(E -2-octenal and 4-oxo-(E -2-octenal (only present in nymales was analyzed with Student's T-test.
To experimentally define origin and termini quantities and ratios, RT-qPCR was applied on genomic DNA (gDNA) using primers with target sites located near each origin and terminus of V. parahaemolyticus, V. cholerae and V. vulnificus (Additional file 1).
Once in the seeds, these metabolites are allocated to different biosynthetic pathways (primarily starch metabolism and storage protein biosynthesis) to produce mainly starch and proteins in precise quantities and ratios.
To directly and quantitatively compare variables having different average values as well as variations in quantities and ratios, we used four different analytical methods to determine the best predictor of CHD.
During the rice seed development, sugars and amino acids transported from source organs are allocated to C and N metabolism to produce starch and proteins in precise quantities and ratios, which requires coordinated expression profiles of genes involved in synthesis of starch and storage [ 36].
