Ben Santer showed that if atmospheric temperature increases are due to the sun then it is stratosphere (upper layer) that should show the increase in temperature, but his data shows that the current increases in global temperature are in the troposphere (lower layer).
T or F
With reference to the above question, the increase in temperature in the troposphere especially within the last 75 years is primarily due to
the sun
random fluctuations in temperature
events unrelated to human activity
increases in CO2 levels by humans burning fossil fuels

Human population size underlies nearly every environmental problem that the planet faces. The environmental problems I am referring to are global warming, deforestation, water and air pollution to name a few. China is noteworthy in establishing limits on the number of children a couple can have as a way of limiting population growth in their nation. Should we consider similar measures in the United States given the growing numbers of people in our country and the idea that natural resources are limited?

1. we discussed the variation among several species of (based on the geological dates we have covered) recent human species that do NOT include neanderthals. I would like for you to identify two, and write three to four bullet points to identify characteristics of each.
2. Next, tell me a bit about Neanderthals, and why they are more intelligent and social than stereotypes that exist in popular culture (think Geico commercials, cavemen, etc).

You are working for a US-based company and have been tasked with integrating an acquisition in Japan (based in Osaka). Prior to this acquisition your company had only a representative office based in Tokyo. What are the four key elements of Human Relations Management and for each element list at least one criterion relevant to your firm’s future success in this marketplace. Where would you establish the administrative offices for the acquired company (explain the rationale for your decision).

If you were a defense attorney, would you defend a foreign national who had been charged with human trafficking and sex slavery? He had been convicted of similar crimes in the past and had done time in prison twice. You have two teenage daughters yourself. He offered you cash for your service. What would you do? Why? Be sure to consider legal ethics when making your decision.

One difficulty in extracting sequencing reads that correspond to mitochondrial DNA from mixed fragments of nuclear and mitochondrial DNA is the nuclear genome contains segments homologous to regions of the mitochondrial genome called "numts." Mammalian genomes contain 50-450 kb of numts (the human genome contains 1005 numts, averaging 446 bp).
Estimate the fraction of reads from fragments of mammoth DNA that are likely to be numts. The mammoth genome is approximately 4.7x10^9 bases in length.

Unfortunately, we now plagued with COVID-19, a disease that is caused by a novel Coronavirus (aka Severe acute respiratory syndrome, SARS-CoV-2). However, there is a significant percentage of those infected with the virus who show mild to no symptoms. On the other hand, others die from the disease complications in a short period of time.
Why is there such a contrasting effect on our human population?
If another cycle or season of the corona virus appears, what are your expectations of the outcomes?
