1. Background information regarding what skin pigmentation is and/or why humans have skin pigmentation
2. Why dark pigmentation is an adaptation to the selective pressure(s) found near the equator
3. Why light pigmentation is an adaptation to the selective pressure(s) found at higher latitudes

Please give a thorough and detailed answer to these three questions, thank you.

The interest rate policy followed by the Central Bank of major world economies (USA, UK, Japan, Europe) are near zero or negative. Discuss the implication this low-interest rate policy for any one type of financial institution (banks, savings, and loans, insurance companies, pension funds, mutual funds, etc.) and examine its possible impact.

Examples of a research topic framed as a central question:

• What is environmental justice and why is it important?
• Do states with sustainable energy tax credits result in more consumers purchasing an electric vehicle or solar panels than those without?
• What are the economic, environmental, and health costs caused by toxic waste sites located near residential areas?

The coronavirus intervened Australia in early 2020.

On 12 May, the Morrison government issued an unprecedented progress report on the delayed budget, outlining the coronavirus pounding to the national economy and the huge outlay to deal with the pandemic.

What were the main issues presented? How do you think they would affect the economy, social and employment situation in the near future?

Fourier's theorem, which essentially states that a real-time function, such as the pressure changes occurring near the surface of the eardrum, can be converted into a spectral representation of the sound. In other words, a sound can be described in either the temporal domain or the frequency domain. Briefly discuss the importance of Fourier's theorem in relation to the physical aspects of sound and to the hearing sciences in general.

Good Economics for Hard Times, Banerjee and Duflo address sources of great anxiety across the world.  They argue that the resources to address these problems are there.  What we need, they say, are ideas that will help us reach across the disagreements and distrust that divide us.  They argue for an intelligent government interventionism and a society built on compassion and respect.  

Drawing upon the readings and lectures, give examples of such interventions

A noise source produces sound mainly at 2500 Hz and an SPL of 95 dB at the location of a worker. In order to decrease this worker’s noise exposure, the employer decides to build a brick wall (? = 400 kg/m2) between source and worker. What would the sound level at the worker’s location be after the wall is built. Assume that the wall is perfect and that the sound must go through it (not around it).

Identify the kind of chips – continuous, discontinuous, segmented or built-up edge, that the following workpieces will tend to form under typical cutting (turning) conditions (i.e. not severely high cutting speeds, depths of cut or feeds). Also, state the reason for why that would be the case.

a) Grey Cast Iron

b) Titanium

c) 4140 Alloy steel

d) stainless steel 316

Briefly explain why the following statement is true, false or uncertain.

Suppose you are evaluating a project such as a road where the annual benefits are increasing with calendar time. The present value (PV) of the investment costs of building the road is the same amount no matter when the road is built. In this case the net present value of the project will be increased if the date that the road is completed and ready for service is postponed.
