Who found the clock? 

Answer the following questions:

1. Describe the experiments that need to be done in order to determine the LD50 and what a chart would look like (sketch this out and label axes and important points)

1. An LD50 value is the best measure available to indicate the potential for a compound to cause harm, to be toxic. However, there are six limitations that we looked at and explained. Below, using your own words, name each of these limitations and explain in detail (and with an example/scenario if possible) why it’s a limitation.

1. What is boiler? The function of a boiler is to produce hot water or steam, depending on its intended use. Hot water boilers are utilized for domestic or commercial heating purposes as well as hot water supply. Steam boilers generate steam to power turbines for power generation and industrial heating applications. Boilers come in different types corresponding to various applications, and they are an important and versatile piece of engineering equipment. They can be designed to burn a specific fuel using various technologies. The fuel is one of the most vital aspects of a boiler because it burns inside the boiler to generate heat. Several sources can be used as fuel in a boiler. For the brewing of beer, boilers also have an interesting application. Tubes of water are heated, and fire tubes are used to heat a tank, producing steam. Steam is then heated for several hours using steam before yeast is introduced, causing fermentation

Answer the following questions:

1. Describe how would you determine if exposure to a compound is toxic?

2. Describe and distinguish chronic and acute exposure to a compound?

3. Define and distinguish local and systemic effect of a compound?

tious system of molecules at 80 K in which the accessi-
ble energies are 0, 2, 6, and 12 quanta, and the dege-
neracies are I, 3, 5, and 7, respectively. Each quantum
is 5.0 X 10-22 J.
(b) Which level is the most highly populated at
equilibrium?
(c) What fraction of the molecules occupies the most
populated level?

Answer the following question:

1. Name and describe, in detail, two reasons why an LD50 values isn’t necessarily useful for someone to know. Pick ONE of the two reasons you described and explain an experiment you could perform to try and help make it more useful to humans. You can have an unlimited budget and access to anything you need that exists currently however you are not allowed to experiment on humans. (7 marks)

equations written in terms of p, q and r.

I think that I understand,but still seem stuck on these questionsfrom my exam.

1. In the garden pea, orange pods (orp) are recessive to green pods(orp +), and sensitivity to pea mosaic virus (mo) is recessive toresistance to the virus (mo +). A plant with orange pods andsensitivity to the virus was crossed to a true breeding plant withgreen pods and resistance to the virus. The F1 plants were thentest crossed to plants with orange pods and sensitivity to thevirus. The following results were obtained:

160 orange pods, virus sensitive
165 green pods, virus resistant
36 orange pods, virus resistant
39 green pods, virus sensitive

a. Perform a chi-square analysis to determine if these genes areindependently assorting. Remember to clearly state your hypotheses.Tell whether you would reject or accept your null hypothesis.
b. If the genes are not assorting, give a possible logicalexplanation as to why you think that the genes fail toassort.


2. A plant species X with n=5 chromosomes was crossed with arelated species Y with n = 7 chromosomes. The F1 hybrids producedonly a few pollen grains, which were used to fertilize the ovulesof related species Z with n=7 chromosomes. A few plants wereproduced from this cross, and all had 19 chromosomes. The F1hybrids (with 19 chromosomes) were mated with related species Wwith n=11 chromosomes. A few plants were produced from the crossand all had 30 chromosomes. Following self-fertilization of the F1hybrids a few F2 plants were produced, each with 60 chromosomes.These plants were phenotypically different from either of theoriginal species and were highly fertile.

a. Explain by diagram and description the events that producedthese fertile F2 hybrids. You must be specific and very clear aboutwhat is happening
b. Give the karyotype of the gametes produced by the highly fertileF2 plants.
c. Using appropriate genetic terminology, tell what type of plantultimately arises as a result of the above crosses.







3. A phenotypically abnormal individual has a phenotypically normalfather with an inversion on one copy of chromosome 7 and a normalmother without any changes in chromosome structure. The order ofgenes along chromosome 7 in the father is as follows:

R T D M centromere P U X Z C (normal chromosome 7)

R T D U P centromere M X Z C (inverted chromosome 7)

The phenotypically abnormal offspring has a chromosome 7 with thefollowing order of genes:

R T D M centromere P U D T R

With a sketch (complete), explain how the abnormal chromosome wasformed. In your answer, explain where the crossover occurred (i.e.,between which two genes). Also, give any other products that mighthave been formed as a result of the crossover you described. Assumethat crossing over does not occur at the centromere.

I need a discussion response to my professors questions on my discussion post

Here is my discussion

1. How can you compare "tulip mania" from 17th century Holland to the dot.com debacle of the 20th century from a financial point of view?

During the tulip mania, the markets were moving up very tremendously. This is because of the increased need for the tulips. The involvement of very many people in the business made many people venture into the company, exhausting the resource thereby leading to scarcity. On the other hand, the dot.com debacle caused a rapid rise in profits for the companies in their share prices. This is because the companies could increase their stock prices by simply adding a ‘.com.' To their name or ‘e’. However, the companies lost heavily when the boom was over. This was caused majorly by the mentality of the companies valuing growth over capitals. Subsequently, the companies ran out of money to sustain the practices. Therefore, the dot.com bubble came to an end with most of the companies on the losing end (Rapp, 2014).

2. Name and explain three ways in which the Internet revolution changed the lives of ordinary citizens.

The internet has made work easier- the internet revolution and its integration in the industrial sector has made the companies shift from the physical offices to online working schedules and programs. The internet has also led to the development and creation of more jobs. This is because the already established companies recruit staff members in the technological sector to help it stay relevant in the technological and social network fields. The internet has made trade easy- the ordinary citizens can make online purchases and be sure that they will get the commodity delivered at their doorsteps.

3. How did the birth of online discount stock brokerages impact the Internet revolution?

Internet revolution became more intense when there was the introduction of online stock. This is because the online stock programs attracted a large number of people (Jennings, 2013).

4. if you were an investor during the dot.com revolution, and you invested primarily in technology stocks, what fundamental principle of finance did you ignore and how did it affect the value of your portfolio?

The principle of ensuring cash flow was ignored during the dot.com bubble. This is because most companies opted for the growth rather than going for profit related ventures (Jennings, 2013).

5. What is diversification and what is its value for investors' portfolios?

Diversification in the investor’s portfolio helps to lower the chances of risks as the returns have higher chances than the portfolios of single investments (Reilly & Brown, 2011).

6. Explain the relationship between the potential return on common stock and the risk of that stock.

Low levels of risk on the common stock result into low levels of potential return on the some stock. This is because an investment that is risked in the market is has a high potential of accruing massive gains for the investor (Reilly & Brown, 2011).
