Among gorillas, chimps and humans, chimps have the largest testes and the most vigorous sperm in terms of swimming speed and endurance, gorillas have the smallest testes and least vigorous sperm, and humans are in between. What does that tell us about female mating behavior now or in the relatively recent evolutionary past?

A) Gorilla females mate relatively often with multiple partners; chimps are nearly monogamous; and on occasion, human females may have multiple partners during a reproductive cycle.

B) Trick question! Only males have testes and sperm, so testes size and sperm vigor cannot tell us anything about female behavior.

C) During a reproductive cycle, chimp females mate relatively often with multiple partners; gorillas are nearly monogamous; and on occasion, human females may have multiple partners.

D) Chimp females mate relatively often with multiple partners, but like humans, gorillas are nearly monogamous.

Human Resource Selection and Development Across Cultures

Firms conducting international business need to be particularly concerned with human resource management issues – including selection, training, and development – to better prepare their personnel for overseas assignments.

Answer the following questions:

1. What selection criteria are most important in choosing people for an overseas assignment? Identify and describe the four that you judge to be of most universal importance and defend your selection?
2. What are the major common elements in an expatriate’s compensation package? Besides base pay, which would be most important to you? Why?
3. What kinds of problems do expatriates face when returning home? Identify and describe four of the most important. What can MNCs do to deal with these repatriation problems effectively?
4. What should your organization do to meet the needs of expatriate employees both in preparing them for their overseas assignment and their eventual return home?

the addition of fermented foods to the diet is becomeing increasingly popular as people seek out ways to make their diet healthier. fermentation is a process undertaken by many different microbes to create energy. humans are able to take advantage of this process to develop many food and beverage products by including different types of bacteria that go through the process of fermentation. for this unit discussion, you will learn more about fermented foods, and their potential impact on human health.
1. locate a recipe for a fermented foods that you would actually prepare and eat. share the recipe with the class. provide an overview of the recipe including the name of the finished food the recipe the ingredients and preparation steps
2 a diet comprised of food is touted as benefical to human health. after reearching this topic, list at least 3 benefits to eating fermented foods.
3 given what you have learned would you recommend including fermented foods to your friends and family? why or why not?

The Elephant ear canal has a length of 17 cm, and is also an open-closed tube. Assume the speed of sound is 343 m/s.

a) Calculate the fundamental frequency of the Elephant's ear canal.

b) Should sound with that frequency appear to be louder to the elephant, or quieter than half that frequency? Also, can the average human hear this sound? What range of frequencies can the average human hear?

d) Draw a diagram of (i) the displacement of air molecules and (ii) the pressure of the air in the ear canal for the frequency you calculated above. You can draw the ear canal as being a straight tube.

The trunk of the elephant can extend up to 3 m long. It acts like an open-closed tube when the elephant blows through it.

c) Calculate the fundamental frequency of the sound that the Elephant can make with it's trunk.

d) If the Elephant blows even harder they can make the next harmonic. What is the frequency of this sound?

please explain in details

What are diminishing returns to capital?

a)

Poor education leads to a decline in human capital.

b)

Rapid increase in population reduces human capital.

c)

Increasing the stock of capital leads to falls in the level of productivity.

d)

Increasing the stock of capital leads to increases in productivity at a decreasing

rate.

b)

there may be too much of an increase for medical care costs.

c)

the increase exactly covers medical care costs.

d)the dollar amount of the social security check does not change.

The State of California increases the amount of food stamps (welfare) it provides to

Use R programming to resolve this; can you please provide details on the code?

A) Create a dataframe – comparativeGenomeSize with the following vectors:

> organism<-c("Human","Mouse","Fruit Fly", "Roundworm","Yeast")

> genomeSizeBP<-c(3000000000,3000000000,135600000,97000000,12100000)

> estGeneCount<-c(30000,30000,13061,19099,6034)

B) Print the organism and estGeneCount for Human and fruitfly.(1)

C) Add a column to this data frame calculating base pairs per gene. To do this, write a function “genedensity” that takes as arguments the genomesizeBP and estimatedGeneCount information, and calculates from this the estimated bp per gene. (3)

Let X be normally distributed with mean 24 and variance 16 b) Calculate the following probabilities: (2)
– P(X ≤ 20)

– P(X > 29.5)

Write a while loop that prints out standard random normal numbers (use rnorm()) (1)
Using next adapt the loop from the last exercise so that it doesn’t print negative numbers. (2)
