Answer:
The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do. The second option fits best with Darwin's theory of natural selection, in which he stated that individuals with the most favorable traits are the ones to survive and reproduce, thus passing their traits onto the future population. The first choice incorrectly believes in Lamarck's theory of evolution in which he incorrectly believed that individual organisms in the population developed a trait that would help them survive (e.g. longer necks in giraffes).
Nucleotides are the monomers in both DNA and RNA
When a signaling molecule binds to the GPCR, the G protein alpha subunit exchanges GDP for GTP. The alpha subunit dissociates from the beta and gamma subunits and interacts with other molecules, ultimately triggering a cellular response. ... GTP is hydrolyzed to GDP, and the signaling molecule comes off of the receptor.
