1. Microarrays are now used as prenatal diagnostic tools to identify aneuploid fetuses in humans. Prospective parents also get to know the sex of their child if microarray profiling is performed. Give some thought to the potential for microarray-based verification of karyotypes in including and beyond the human species. Then indicate whether the sex of a fetus could be determined in the following species by this method. If so, for each case, should the microarray be hybridized to genomic DNA or cDNA? If either DNA or cDNA would be inappropriate, explain why.

1. Chickens (sex is determined by ZW chromosomes)

2. Snakes (sex is determined by alleles of a single gene)

3. Agama lizards (sex is determined by the temperature at which eggs hatch)

4. Twelve year old human suspected to be X0 (Turner’s syndrome)

The pattern of genetic similarity and differences among human populations allows us to reconstruct the evolutionary history of our species. Label the lettered parts of your answer.

A. What taxonomic group would include L1 + L2 + L3, but not Homo sapiens neaderthalensis?

B. Where and when did that (L1 + L2 + L3) taxonomic group originate?

C. Was there ever any interaction between (any part of the) taxonomic group you named above and Homo sapiens neaderthalensis; if so, what was the nature of that interaction?

D. Drawing on the information in your answers to parts A, B, and C, and on patterns of current human genetic diversity, explain the sequence and timing of events that led to the present situation, with a single kind of hominin occupying the whole planet.

Human Resource Management

Motivating employee is of key concern to most firms, especially those operating in the competitive Ghanaian metal industrial environments. To these firm-types, human resource is considered unique, and the management of employees’ motivational expectations is deemed a prerequisite for organizational success. This mindset has necessitated the need for such firms to look for best ways of developing work-motivation systems at their workplaces that are all-encompassing, and which can have the potency to satisfy employees’ work-motivational expectations and create the requisite driving forces in them towards increased performances and productivities.
Required:
Explain, with examples, the character of such work motivation system, and the benefits it stands to provide the firms, if it is well designed and managed. Also argue with justifications, how the design and management of the system should be approached.

Background

Pick one or possibly a "combination" of 2 heavy metals ....which you must now try to justify as the real CULPRITS in the continuing disease we see in people who had this exposure in the past ! try to explain (as a Toxicologist) why you think that heavy metal(s) you selected could be the cause of the disease and death seen in those who were exposed ! Be sure to give chemical, biological, physiological, toxicological reason for your selection. How does this impact on human physiology or cellular/ biochemical activity of humans or human cells .

As a toxicologist, which heavy metals do you think caused long term effects but also killed those in 911? I'm thinking sulfate or Zinc but I'm not sure.

Suppose that the total checkable deposits in the entire banking system of an economy is $100 billion. The total required reserves are $10 billion. Further, banks do not hold any excess reserves, and individuals do not hold any cash in the economy.

A) In this economy, if the Federal Reserve buys $10 million worth of government securities, then by how much will the money supply increase?

B) Will the change in money supply be greater or lesser than what you derived in part A if the banks hold excess reserves and individuals hold cash? Explain your answer.

Suppose that the U.S. economy is in a recession, and the Federal Reserve Bank decides to use monetary policy to help the economy recover.

The goal is to increase the real GDP by $500 billion. The Federal Reserve Bank chooses open-market operations as the desired tool to achieve this.

It has the following information about the economy:

(1) all money is held as deposits, and banks do not hold excess reserves;

(2) a $1 change in the money supply leads to a $2 change in real GDP; and

(3) the reserve requirement on banks is 10%.

Given this information, answer the following questions:

A) Should the Federal Reserve Bank BUY or SELL Treasury securities to achieve this?

B) What is the value of open-market operations that the Federal Reserve Bank must carry out to help the economy recover from the recession?

C) Explain the logic behind how the open-market operations can help the economy recover.

d. The Human Development Index and real GDP are equivalent ways of measuring economic development.
