A) Explain in one paragraph why, in your opinion, forensic anthropology and bioarchaeology employ race or ethnicity according with the film. B) Please respond to the following question in one paragraph: When NOVA reconstructs the history of human migration from Africa, it is presenting an antiquated theory of how people arrived in the Americas.  Which model did they put forth?  What is the most recent theory and evidence?  Reference your work.

Pls help ASAP on all PLS I REQUEST

Can someone please help

need help please and thanks dont understand only need help with C-F Learning Goal: As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7).   Part A - Difference in binding free eenergies Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol. The margin of error is 2%.   Part B - Compare difference in free energy to the thermal…

The Background section of this lab explains why weight percent (%w/w) can be useful for comparing the relative amount of a desired or "active" compound in different products. During the lab, a major goal will be to decide which of your experiment flasks yield data that would allow you to correctly calculate the %w/w of sodium bicarbonate in these tablets. Let's assume that you correctly choose one flask for this calculation. If the amount of NaHCO3 in that flask was 2.80 g and the original weight of the tablet was 4.50 g, what is the %w/w NaHCO3 in the tablet that went into this flask? GIVE YOUR ANSWER TO TWO DECIMAL PLACES. Your Answer: Answer

Subpart 1-5

This is an ungraded practice exam in which he gives us the answers but I would still like to know the reasoning behind

Figure 7 of Conrad et al. (1999) shows the variation in C-isotopic composition of CO2 as a function of the concentration of methane measured in the soil and aquifers of a site contaminated in the residues of aviation fuels. Explain briefly the aim of these particular measurements made to the environmental study. Also explain briefly why there is a difference in isotopic composition of CO2 obtained via aerobic degradation and methanogenic degradation of AVGAS (fuel residues as contaminants) and the linear "mixing relationship" noted in Figure 7. 35 30 methane oxidation methanogenic degradation of AVGAS 25 - 20 15 Sampling Locations 10 aerobie degradation of AVGAS A 12 • 13 5 6. 14 O 20 O 21 9 O 10 -30 -25 -20 -15 -10 -5 8®C (%c) of CO, Fig. 7.

Figure 7 of Conrad et al. (1999) shows the variation in C-isotopic composition of CO2 as a function of the concentration of methane measured in the soil and aquifers of a site contaminated in the residues of aviation fuels. Explain briefly the aim of these particular measurements made to the environmental study. Also explain briefly why there is a difference in isotopic composition of CO2 obtained via aerobic degradation and methanogenic degradation of AVGAS (fuel residues as contaminants) and the linear “mixing relationship” noted in Figure 7.   How does the degradation process influence the CO2 isotopic signature ? I don't understand why the CO2 from aerobic degradation is lighter than the one from methnogenic degradation ?
