You are studying a population of wild turtles on a remote Pacific island. You have been following the allelic frequencies at a single two-allele locus 'S', which controls embryonic survival through simple Mendelian inheritance with dominance. The population has been in Hardy-Weinberg equilibrium at this locus for many generations.

At Hardy-Weinberg equilibrium, the frequency of the recessive allele S^d is 0.88

The genotypic frequencies at Hardy-Weinberg equilibrium are as follows:

f(S^DS^D) = 0.0144

f(S^DS^d) = 0.2112

f(S^dS^d) = 0.7744

An increase in ocean temperature between 2018 and 2019 is thought to have driven the population away from Hardy-Weinberg equilibrium at the S locus.

The numbers of sampled offspring by genotype after the 2019 hatch are as follows:

S^DS^D : 200

S^DS^d : 200

S^dS^d : 40

Calculate the relative fitness (W) values for each genotype (you will need all these values in a subsequent step).

a) The relative fitness value for the S^dS^d genotype is [A] (enter your answer as a decimal in the form '0.x'; do not spell out the number as a word; there are no units to include)

b) The type or form of natural selection that has occurred is [B] (use the specific phrase that describes this form of selection completely!).

Now, calculate all genotypic frequencies in the 2019 offspring (first generation after selection):

c) post-selection f(S^DS^D) = [C] (perform this and the following two calculations (d and e) to four significant figures after the decimal point; enter your answers in the exact form '0.wxyz'; make sure to round off correctly; there are no units)

d) post-selection f(S^DS^d) = [D]

e) post-selection f(S^dS^d) = [E]

f) The frequency of the S^d recessive allele in the 2019 offspring (first generation after selection) is [F] (perform the calculation with four significant figures, then round off to 2 significant figures in the final answer; enter your answer in the exact form '0.xy')

We can apply PCA to reduce features in a data set for model construction. But, why do we still
need regularization?

One expert contends that sales training is not at all complicated. He predicts that regardless of advances in communication, resources, technology, and training tools, the basic selling skills that trainers teach salespeople will change very little from those that have been successful during the past 50 years. What will change, according to the expert, is how salespeople are trained to use these skills effectively. Do you agree with this prediction?

PLEASE GIVE MORE THAN YES OR NO ANSWERS

a) Does the pitch of the noise made by striking a bottle get higher or lower as you fill the bottle with water?

b) Does the pitch made by blowing across the top of the bottle go up or down as you fill the bottle?

c) Why is there a difference between these two noises? In your answer, comment on the source of the noise in each case (i.e. What is vibrating?).

d) Using what you know about harmonics and resonance, explain how different pitches are created when you blow across the bottle opening with different liquid levels.

e) What wave property allows you to hear noise through a bottle held up to your ear when someone blows across the top of a bottle across the room, and how does the sound transmit from one bottle to the other? Will the pitch sound the same as the one made by the person across the room?

Write a client program that writes a struct with a privateFIFO name (call it FIFO_XXXX, where XXXX is the pid that you got from the getpid( ) function) to the server. Have the server read the privateFIFO name and write a message back to the client. Read the message and print it on the client side. Take screenshots of the output from your client and server programs. Send the output to Blackboard. What I'm checking for on this homework is that the name got created in the client and passed correctly to the server and the server can respond to the client. Turn the background of your window white and increase the font size.

Write in C, Will be used on Putty.

Thank you.

Old World Charm, Inc. specializes in selling scented candles. The company has established a policy of reordering inventory every other month (which is 6 times per year). A recently employed MBA has considered New England's inventory problem from the EOQ model viewpoint. If the following constitute the relevant data, what is the extra total cost of the current policy compared with the total cost of the optimal policy? Enter your answer rounded to two decimal places. Do not enter $ or comma in the answer box. For example, if your answer is $12,300.456 then enter as 12300.46 in the answer box. Ordering cost = $10 per order Carrying cost = 20% of purchase price Purchase price = $15 per unit Total sales for year = 1,000 units Safety stock = 0

1.What is Capital Asset Pricing Model (CAPM)? What is it used for ?

a) There have been discussions about how useful the Capital Asset Pricing Model (CAPM), does it actually work or is "beta dead"?

b) Why is the model important in Finance ?

So I went through a lab experiment last week, basically, We have a mixture and we remove iron with a magnet, we than seperate naphthalene by sublimation (by heating a flask). Than we have urea which is the only component that can dissolve in water which is obtained by crystallization after seperation from the polypropylene which floats on the water and the sand which sinks.

1) Describe the prinicpal diffuclties you encountered in obtaining a clean seperation and in collecting the seperated components without loss.

I really forgot the diffuclties I ecountered, anyone got an idea?

A student at a predominantly African American high school insists on wearing a T-shirt that some say advocates white supremacy ideologies. Using the preferred freedoms approach, convince the school board to allow the student to wear the shirt to class.

You are in charge of security at a casino, and there is a thief who is trying to steal the casino's money! Look over the security diagrams to make sure that you always have a guard between the thief and the money!
There is one money location, one thief, and any number of guards on each floor of the casino.

Task in Java, Python and CPP:
Evaluate a given floor of the casino to determine if there is a guard between the money and the thief, if there is not, you will sound an alarm.

Input Format:
A string of characters that includes $ (money), T (thief), and G (guard), that represents the layout of the casino floor.
Space on the casino floor that is not occupied by either money, the thief, or a guard is represented by the character x.

Output Format:
A string that says 'ALARM' if the money is in danger or 'quiet' if the money is safe.

"Queer is understood as an umbrella term that refers to a range of sexual identities that are not "straight." (Siobhan B. Somerville). A key concept in queer theory is the notion of "heteronormativity" which refers to institutions, structures of understanding, and practical orientations that make heterosexuality coherent and privileged. "

1. Do you think in modern days the word "queer" is more accepted? Why or why not?

2. Also do you think there should be a non binary option on licenses? Why or why not?

1. Consider the language defined as such:

L = { w$w’ : w is a string of numbers 0-9 and can be of length ≥ 0, and w’ is the reverse string of w}

Write a recursive grammar that defines all strings in the language.

2. Using the language above, write the Java code (using recursion) that will recognize if a string is part of the language or not.
