You prepared a series of tubes with increasing concentrations of maltose. After reading the absorbance of these tubes you prepared a Maltose Standard Curve. The equation of the line of best fit you obtained is:
y = 1.9x -0.053
You then did an experiment to study the effect of pH on amylase activity. Amylase was mixed with starch and buffer of varying pH in several tubes, which
were incubated for 10 minutes at 45°C. The DNS assay was done and absorbance readings were collected and are shown in the table:

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

preservation because he preserves part of the land and preserves means save

explanation:

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
