Ecological systems are naturally variable in their physical and biological characteristics, and exist in a dynamic equilibrium with their biota. Systems with greater diversity of species are generally more stable and resistant to external disturbances. Keystone species significantly impact ecosystem functioning and overall community stability. Therefore, variability and stability are important for the proper functioning of ecological systems.

briefly write about the variability of natural systems and the significance of the rate of change
and predictability to the stability and functioning of ecological systems
Solution
Answer:- The natural ecological systems are usually variable in physical and biological
characteristics that are always in dynamic equilibrium with their biota. The ecological systems
which diverse both in eveness and richness of species are usually stable and less prone to
extinction and resist the disturbances created by any external agency. The keystone species play
an important role in the ecosystem functioning and overall community stability. Thus variability
and stability are essential for functioning of ecological systems.

X-Linked Recessive Write three rules to keep in mind when counseling someone about the likelihood of inheriting an X-linked recessive condition: About parents\' genotype. About parents\' phenotype. About the probability of the offspring showing the trait. If instead of having Hemophilia C (autosomal recessive), Lisa Keller\'s brother had Hemophilia A (X-linked recessive), what would be the probability that she was a carrier? 25% 50% 67% 100% More information is required to answer this question. Solution About genotype of parents- If the mother is a carrier i.e. carrying the recessive allele on one of her X chromosome and the father do not have the recessive allele in his genotype, then none of the daughters will suffer from the disease (since they will inherit only one recessive allele from the mother) but sons will have a 50% probability of suffering from the disease as they will inherit the recessive allele from the mother and the Y chromosome from the father, although there is a 50% probability of inheriting the wild type allele from the mother. Now if the mother is suffering from the disease i.e. has the recessive allele on both the X chromosome while the father is healthy having no allele for the disease, the daughters will always be a carrier but never suffer from the disease as they eill inherit the healthy wild type allele from the father as one X chromosome comes from the father and the other X chromosome from the mother. The sons will however all suffer from the disease as they inherit the Y chromosome from the father and the X chromosome having the recessive allele causing the disease will be inherited from the mother. Now suppose the mother is a carrier i.e. carries the recessive allele only on one X chromosome but the father suffers from the disease making his genotype XrY (Xr denoting recessive allele carrying X chromosome), then, 50%of their son will duffer from the disease while 50% of the daughters will also have a chance of suffering from the disease. If both the parents do not have a single recessive X linked disease gene on any of their X chromosome then none of the children will suffer from the disease. About phenotype of parents- If the mother is a carrier i.e. have the diseased allele on only one X Chromosome, then the phenotype of mother will be normal. But the father can never be a carrier for a X linked recessive disease as males have only one X chromosome. If the diseased allele in present on that X chromosome in males it will be expressed as there is no dominant healthy wild type allele to dominate the diseased gene. Thus if the father has the recessive diseased allele on X chromosome, the father\'s phenotype will be expresding the disease while if the father do not have the allele he will be healthy. On the other hand for the mother to express the disease the recessive allele has to be present on bith her X chromosome. Probability of offsprings showing the trait- If mother is a carrier and father is normal, then 5.

Write a Java Class to Implement a Generic Linked List Your list must be implemented as a singly-linked list of generic nodes, where each Node object has two instance variables: an object of the “type variable” class, and a pointer to the next node on the list. Your class will contain separate methods to handle each of the operations read from a data file (see II., below) Your class will also override toString() to return the objects on the list in the order in which they occur. Write a Test Class for Your LinkedList Class Your main method will read list operation instructions from a data file, until end-of-file and call the appropriate LinkedList method to execute each one. After each operation is executed, print out the operation and the updated list. The data file to be used is on the class web site and the operations are: APPEND X - Append object X to the end of the list ADD N X - Insert object X as the new Nth element in the list, increasing the size of the list by 1 E.g. Suppose the list is: head -> 1 -> 2 -> 3 -> 4->null After ADD 3 7 it would be: head -> 1 -> 2 -> 7 -> 3 -> 4->null DELETE N – Remove the Nth object from the list SWAP M N - Interchange the positions of the Mth and Nth objects on the list For credit, the two nodes must actually \"trade places\" in the list, and not merely swap their data values REVERSE - Reverse the order of the objects on the list This must be done by reversing the order of the nodes themselves, rather than by swapping the data stored To get credit for your reverse() method, it must use either one of these 2 algorithms: For each node on the list except the current “head” node, delete the node and insert it as the new head Use your swap() method 6. CLEAR – Clear the list (make it empty) No credit will be given for programs that use any additional data structures – either from the Java API or programmer defined -, other than your own LinkedList class txt file: Solution //Java Program to Implement Singly Linked List import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; /* Class Node */ class Nodes { protected Object data; protected Nodes next; /* Constructor */ public Nodes() { next = null; data = null; } /* Constructor */ public Nodes(Object d,Nodes n) { data = d; next = n; } /* Function to set link to next Node */ public void setLink(Nodes n) { next = n; } /* Function to set data to current Node */ public void setData(Object d) { data = d; } /* Function to get link to next node */ public Nodes getLink() { return next; } /* Function to get data from current Node */ public Object getData() { return data; } } /* Class linkedList */ class linkList { protected Nodes start; protected Nodes end ; public int size ; /* Constructor */ public linkList() { start = null; end = null; size = 0; } /* Function to check if list is empty */ public boolean isEmpty() { return start == null; } /* Function to get size of list */ public int getSize() { return .

Write a class (BasketballTeam) encapsulating the concept of a team of basketball players. This method should have a single instance variable which is an array of basketball player objects. In addition to that class, you will need to design and a code a Playerclass to encapsulate the concept of a basketball player, assuming a basketball player has the following attributes: a name, a position, number of shots taken, and number of shots made. In your Player class you should write the following methods: A constructor taking a String for the name, a String for the position, an int for the number of shots taken, and an int for the number of shots made. Accessor, mutator, toString, and equals methods. A method returning the individual shooting percentage. Avg = Shots Made / Shots Taken. Hint: This method should return a double!!! In your BasketballTeam class you should write the following methods: A constructor taking an array of Player objects as its only parameter and assigning that array to the array data member of the class, its only instance variable. Accessor, mutator, toString, and equals methods. A method checking if all positions are different, returning true if they are, false if they are not. A method returning the shooting percentage of the team. Team Shooting Percentage = Total Shots Made / Total Shots Taken Hint: This should return a double!!! Also, this is not the average of the the averages. A method checking that we have a center (that is, the name of the position) on the team. If we do not have any return false; otherwise, it returns true; A method returning void that sorts the array of Player objects in ascending order using the number of shots taken as the sorting key. A method returning the array of Player objects sorted in ascending alphabetical order by name. Hint: Use compareTo method of the String class. A method returning the name of the player with the most shots made. A method returning the name of the player with the highest shooting average. In your BasketballTeamClient class, when you test all your methods, you can hard-code five basketball Player objects. This client should call all 12 methods including the constructor for full credit. When writing the Player class you should write a PlayerClient class that tests all its methods before integrating into BasketballTeam class. Solution public class Player { //Attributes private String name; private String position; private int shotsTaken; private int shotsMade; /** * Constructor * @param name * @param position * @param shotsTaken * @param shotsMade */ public Player(String name, String position, int shotsTaken, int shotsMade) { this.name = name; this.position = position; this.shotsTaken = shotsTaken; this.shotsMade = shotsMade; } /** * @return the name */ public String getName() { return name; } /** * @param name the name to set */ public void setName(String name) { this.name = name; } /** * @return the position */ public String getPosition() { return position; } /** * @p.

Which of the following would you expect to happen in a plant that does not have enough water (multiple answers are correct) Without water, the plant cannot make the sugar it needs to grow the stem begins to dry out growth would be stunted because it is difficult to move nutrients around Without water, the plant would become limp. Solution Answer: All the choices given are correct! If Plant that does not have enough water; (a) Without water, plants cannot make the sugar it needs to grow. Plants make their own food by the process of photosynthesis.The amount of water, sunlight and carbon dioxide directly influences the process of food production for plant growth. Thus the process of photosynthesis slows down and even stops when water is absent, which causes internal food supplies to diminish. (b) the stem begins to dry out Scarcity of water leads to loss of turgor pressure. Stomata on the stem surface close as a result of less water (for water conservation) and as a result stem dries out. (c) the growth would be stunted because it is difficult to move nutrients around. As water moves above the plant system it carries vital minerals and nutrients to different areas of the plant. The stomas on the leaf and stem surface release waste products (oxygen) into the environment and takes CO2 in. This process of transpiration maintains the turgor pressure and also cools the plant in sunlight. In scarcity of water, transpiration process slows and, the plant show stunded growth due to lack of nutrients supply. (d) Without water the plant would become limp Turgor pressure holds the plant cells and keeps them erect. This pressure is lost without water and plants begin to collapse (wilting!) or give a limp appearance..

What is the value of including personal information about yourself and your lifestyle when researchers are looking at your DNA? How does study different than many other similar sets of data gathered from GWAS and SNP Haplotypes?What do you think about the scope and purpose of this type of genetics data study. Solution Answer to including personal information and lifestyle lies in phenotype differences. Phenotype is influenced by genotype and environment. Hence although scientists and researchers look for DNA or genetic material of an individual but also take a look on the environmental conditions or life style which influences the phenotype of an organism. GWAS (Genome wide association study) is study of genetic variants which are associated with a trait like any major disease. By using SNPs (Short nuclear polymorphisms) short interspersed regions can be identified to locate the traits of interest. The environmental factors like sunlight can differ the response of an individual to it. One individual can be sensitiove to it but the other could be diseased on exposure to sunlight, thus having a knowledge about individual\'s lifestyle helps in tracking previous information. The scope of GWAS has wider implications. Disease dignosis using genetics data helps in developing drugs relating to it. It can be used to identify genes from different organisms. Ancestral hierarchy can be established..

What is a voluntary response sample? Solution Voluntary response sampling is heavily biased because it focuses on volunteered survey answers rather than a random sampling. What makes this biased is because the only people who volunteer are those who have a particular interest in the topic of the survey. They only include people who choose volunteer, whereas a random sample would need to include people whether or not they choose to volunteer. Often, voluntary response samples oversample people who have strong opinions and undersample people who don\'t care much about the topic of the survey. Thus inferences from a voluntary response sample are not as trustworthy as conclusions based on a random sample of the entire population under consideration..

Question is about the Enron Scandal in 2001... There is no case study... it is just based off of the case in general. What impacts, if any, do emerging technologies have on the ethics of this case? If not applicable to this case, discuss possible overall impacts on ethical situations in general. Please provide sources Solution Enron was a company that thrived use of latest technologies and had a code of ethics that prohibited managers and executives from being involved in another business entity that did business with their own company. But, the codes of ethics that was voluntary and was set aside by the top management and the board of directors. The legal structure permitted top management to enter the arrangements, that constituted an interest conflict and while the fiduciary duty states the managers and executives hato d to behave and act in the best interest of the shareholders and the company. However there was discretion allowed to exercise their own business judgment related what was in the best company\'s interest. A unethical and illegal activities path was followed. Managerst was succumbing to greed and dishonesty by secretly exercising stock options and constructed fake falsely financial report which enabled to hide billions of dollars of debt. Using this approach Enron management created a noncompliance that existed different than GAAP or SEC reporting standards and abandoned the basic accounting standards of integrity. The main failure of the Enron accounting in terms of ethicas are as follows: -- Poor Management Accountability: Weak management was virtually not accountable to anyone as long as the company showed dramatic stock increases that were justified by the growth in the earnings. --Accounting Rules: The accounting activities became more complex and rule-oriented. Accounting permitted practitioners to take obscure pronouncements, like dealing with Special Purpose Entities that were primarily designed for transactions of leasing, and apply the pronouncement to certain entities for which these accounting was never intended. -- Weak Corporate Governance: Although the board seemed to be independent, but majority of the board members had close ties to company managers through philanthropic organizations. --Enthusiastic Financial Analyst Community: The analysts that were riding the bubble of the financial dot-com economy made a conclusion that they did not have proper tools for the valuation of the emerging companies. --Biased Banking and Investment Banking: Several big financial institutions were willing participants in the process as they were promoted with large underwriting fees for other Enron work. -- Lack of an Independent External Auditor: During the time of Enron, there existed mainly five large external auditing firms who were referred as professional service firms with their business in diverse line. All such firms had big consulting practices. The internal audit work for Enron was performed by Arthur Andersen. Moreov.

The second is your reflection on the article – what it makes you think about. Each paragraph contains a minimum of five sentences. Submit to me on blackboard. The document should include the paper and the annotated bibliography Solution Carter and Barker (2010) describe listing as a twofold bookish discipline—the organized listing of books (enumerative bibliography) and therefore the systematic, description of books as physical objects (descriptive bibliography). These 2 distinct ideas and practices have separate rationales and serve differing functions. Innovators and originators within the field embrace W. W. Greg, Fredson Bowers, Duke of Edinburgh Elizabeth Gaskell, G. Thomas Tanselle. Bowers (1949) refers to enumerative listing as a procedure that identifies books in “specific collections or libraries,” in an exceedingly specific discipline, by Associate in Nursing author, printer, or amount of production (3). He refers to descriptive listing because the systematic description of a book as a fabric or physical object. Analytical listing, the cornerstone of descriptive listing, investigates the printing and every one physical options of a book that yield proof establishing a book\'s history and transmission (Feather 10). it\'s the preliminary part of listing description and provides the vocabulary, principles and techniques of research that descriptive bibliographers apply and on that they base their descriptive follow. Descriptive bibliographers follow specific conventions and associated classification in their description. Titles and title pages ar transcribed in an exceedingly quasi-facsimile vogue and illustration. Illustration, typeface, binding, paper, and every one physical parts associated with distinctive a book follow conventional conventions, as Bower\'s established in his foundational piece, The Principles of listing Description. The thought expressed during this book expands substantively on W. W. Greg\'s groundbreaking theory that argued for the adoption of formal listing principles (Greg 29). basically, analytical listing is bothered with objective, physical analysis and history of a book whereas descriptive listing employs all information that analytical listing furnishes then codifies it with a read to distinctive the perfect copy or style of a book that almost all nearly represents the printer’s initial conception and intention in printing.

Present and explain all the elements in Freud theory. Solution In the year 1905, Freud developed a model of the mind, which he used to describe the features of the mind’s structure and function. He stated that on the surface of the mind is consciousness, which consists of those thoughts that are the focus of our attention now. The preconscious consists of all which can be retrieved from memory. The third and most significant region is the unconscious. Here lie the processes that are the real cause of most behaviour. In 1923, Freud developed a structural model of mind. Mind has entities like id, ego and superego. Freud assumed the id operated at an unconscious level according to the pleasure principle. Eros, or life instinct, helps the individual to survive; it directs life-sustaining activities such as respiration, eating. The ego develops from the id during infancy. The ego\'s goal is to satisfy the demands of the id in a safe a socially acceptable way. The superego develops during early childhood (when the child identifies with the same sex parent) and is responsible for ensuring moral standards are followed. Freud\'s theory is very good at explaining behavior. His theory of cognitive psychology has identified unconscious processes, such as procedural memory and automatic processing..

It yields ATP and NADH C. It forms ATP via substrate level phosphorylation D. none of A-C are false; all are true Solution Answer: 1). C. Inorganic molecules as the initial electron donrs Lithotrophy is the use of an inorganic compound as a source of energy. Most lithotrophic bacteria are aerobic respirers that produce energy in the same manner as all aerobic respiring organisms: they remove electrons from a substrate and put them through an electron transport system that will produce ATP by electron transport phosphorylation. Lithotrophs just happen to get those electrons from an inorganic, rather than an organic compound. Lithotrophic sulfur oxidizers include both Bacteria (e.g. Thiobacillus) and Archaea (e.g. Sulfolobus). Sulfur oxidizers oxidize H2S (sulfide) or S (elemental sulfur) as a source of energy. Similarly, the purple and green sulfur bacteria oxidize H2S or S as an electron donor for photosynthesis, and use the electrons for CO2 fixation 2). D. All forms of energy production require a proton motive force 3). D. none of A-C are false; all are true.
