I believe that the youth movement originated with the baby boomers, the huge generation born after the world war II. By 1970, 58.2 % of the population in America was under the age of 35 years. The economic boom of the 1950s meant more families could afford to send their children to College. College life gave the young people a sense of freedom and independence. It was on college campuses across the nation that youth protest movements began and reached their peak.
Lunar eclipses are more wildly visible because Earth casts a much larger shadow on the moon during a lunar eclipse than the moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar!. ;)
Answer:
People are not aware of their causes and impacts.
Explanation:
First, people just seem to think that a little bit of harm won't impact the world at all, but that little bit for everyone adds up and the magnitude is a lot worse than people would imagine. Next, even if they/we do know the scale, they don't know how to help or are not interested enough to try and fix the problem. We all think that we won't be able to help enough to fix the issue.
<span>Evidence that human activities influence the global climate system continues to accumulate. Data indicate that Earth's surface temperature is rising. This increase can be attributed, in part, to human-caused increases in greenhouse gases such as carbon dioxide. It is becoming apparent that these climatic changes are negatively affecting physical and biological systems worldwide.</span>
A bacterium has a faulty lac operon in which there is a structural defect in the operator. In this bacterium there is a structural problem with a segment of DNA that binds a repressor.
- A protein known as a repressor binds to an operator site. The operator in this instance (and numerous others) is a section of DNA that lies just downstream of the RNA polymerase binding site or overlaps with it (promoter). In other words, it lies between the operon's promoter and its genes.
- The repressor protein inhibits the synthesis of messenger RNA by attaching to the promoter region of the gene(s) (mRNA). The control of gene expression in cells requires repressor proteins.
- Thus, by physically impeding the RNA polymerase's ability to operate, these repressor proteins stop the gene from being transcribed.
