1.I was looking at my notes on protein structure and I am trying to understand quaternary structures for proteins.
I understand that primary, secondary, and tertiary structures are encoded by one gene each. However, I am not entirely sure if quaternary structures are encoded by one or multiple different genes.
The reasons why I am a little confused is for two reasons. Firstly, quaternary structures are made up of more than one protein subunit (i.e. multiple polypeptides). Secondly, as I understand, Hemoglobin, for example, has different subunits, each of which is encoded by a different gene. Does this necessarily mean that all quaternary structures are composed of proteins encoded from different, separate genes?
If quaternary subunits are encoded by different, separate genes, can those different genes be located on different loci, or are all of the subunits necessarily encoded by the different gene but its mRNA molecule is spliced differently?
2. (‘JJ) uses a certain machine to produce carjacks. The machine cost the company $90,000 three years ago. The reduced
s ago. The reduced book value now stands at $60,000. A new model of the machine is currently available for $139,350. The new machine has a useful life of five years, at which time it will be sold for $20,000. Using the new machine, the expected unit sales of the car jacks would be 6,000 car jacks per annum. The estimated unit selling price is $35 for the first year. As a result of the COVID-19 pandemic in Singapore, JJ is experiencing labour shortage. JJ will have to transfer workers from another department to the new project. These workers earn a contribution of $2 per direct labour hour in their original department. The fixed overhead cost would be $2.20 per hour and this is expected to remain unchanged. JJ’s products are being sold to a distributor. The sales agreement allows the selling price to rise at the rate of 10 percent per year after the first year. The unit cost price, except for fixed costs, is expected to increase at the same rate as the selling price. Working capital requirements are expected to be $15,000 in the first and second years, increasing to $18,000 in the third year and is expected to remain at this level till the end of the project. All the amounts of working capital will be recovered at the time of project termination. The new project uses cutting-edge technology and so enjoys a tax holiday from the authorities. The drawback of using this high-risk approach is that the new project requires a minimum return of 27 percent per annum. Required: Identify the relevant cash flows for the decision as to whether JJ should proceed to purchase the new machine. Note: To show all workings with accompanying explanations. Word count requirement: 800
3.I have to create a theme statement for Romeo and Juliet and here are my ideas but all my teacher
l tell me is that they need work.
Here are my there ideas:
1. Love is manipulative and makes its subjects act in their own best interests rather than in their interests as a whole.
1a. To support the idea that if Romeo and Juliet each would have communicated better and worked together, they could have avoided death
2. Love doesn't abide by societies rules.
2a.To support the idea that Romeo and Juliet's families would never support this but their love didn't care
3. Hatred has a negative impact and many are affected by it, no matter the severity.
3a. To support the idea that the families feud resulted in a negative way because if they would have not been so hateful, maybe Romeo and Juliet could have lived to be happy
Here is a scenario where you would have to deal with a customer who is being rude and abusive. You
work for as a customer service representative at a call center for a company that makes exercise equipment. A customer calls in complaining that her treadmill motor is smoking. She has called in previously and was informed that her
warranty has been voided because she did not follow the maintenance instructions in the handbook for her machine. She is upset because no one ever told her about maintenance when she bought the machine. She starts calling you a crook for robbing her, and continues to call you names (including some we can’t print).
Explore what steps you would take in this situation to remain calm and relaxed.
How would you go about de-escalating the situation?
How do you avoid correcting the customer and putting her on the defensive?
If it became absolutely necessary, how would you phrase a warning to refrain from personal attacks?
6.You will be assembling 4 expressions using order of operations. The trick to this project is that you’ll be
ou’ll be using the same 4 numbers written in the same order. The only thing that will change in each expression will be the tools you’ll use from your toolbox. The tools that you’ve learned so far for order of operations are parentheses, exponents, multiplying, dividing, adding, and subtracting.
Here are the four numbers. Keep them in this order:
18 2 4 3
Here are the tools in your toolbox:
The 2 and 3 represent exponents, so you are allowed to square or cube a number.
Listed below are the values you need to create.
