Tree ring patterns provide information about precipitation and other conditions during the time the tree was alive. Scientists can learn even more about precipitation and temperature patterns by studying certain chemicals in the wood. Modern trees can be interesting to compare with local measurements (for example, temperature and precipitation measurements from the nearest weather station). Very old trees can be even more interesting because they offer clues about what the climate was like before measurements were recorded. In most places, daily weather records have only been kept for the last 100 to 150 years. Thus, to learn about the climate hundreds to thousands of years ago, scientists need to use other sources such as trees, corals, and ice cores (layers of ice drilled out of a glacier or ice sheet—mostly in Greenland and Antarctica).
Partial mass of C, 12*2 = 24
Partial mass of H, 1*5 = 5
Partial mass of N, 14
Partial mass of O, 16
Now, total molar mass would be 24+5+14+16 = 59
mass % of carbon = 24 * 100 / 59 = 40.67%
Answer:
B. binds to the tryptophan repressor when the repressor is bound to tryptophan.
Explanation:
Bacterial genes are commonly composed of operons that are activated or deactivated depends on the needed. If the bacteria need, for example, an amino acid such as tryptophan for synthesizing proteins. An activator "turns on" the transcription that the operon has and produces the amino acid.
On the other hand, if the bacteria have a high presence of tryptophan amino acid, a repressor binds to the tryptophan operator and avoids the amino acid transcription, in consequence, constrain the tryptophan production.
