Note the image showing a series of batholiths on the landscape. How did those batholiths get exposed at the surface? Batholiths crystallize below the surface but were later exposed by way of erosion of overlying material. Batholiths crystallize below the surface but then flow upwards towards the surface. Batholiths crystallize at the surface, so they are simply still in place. The batholiths were washed downhill from distant mountains and deposited here..

Not yet answered Points out of 1.00 Flag question It seems kind of weird to be discussing atmospheric carbon dioxide levels in a class that focuses on microbes. Which of the following scenarios describe a way in which microbes might help reduce atmospheric CO 2 levels? Check all that apply and only those that apply. a. Fungi can attach to plants' roots in the form of mycorrhizae and improve growth, which leads to increased CO2 sequestration. b. Nitrogen- fixing bacteria can improve plant health by converting atmospheric nitrogen into organic nitrogen that gets used by plants, which leads to increased growth, photosynthesis, and CO 2 uptake. c. Phytophthora infestans can be used for genetic engineering, which leads to reduced plant growth in the winter, and thus reduced atmospheric CO 2 levels during the colder months. d. The Tomato Mosaic Virus can cause a mosaic pattern on tobacco leaves, which improves photosynthesis rates in the the plant itself, thus causing increased conversion of CO 2 into plant sugars..

Not yet answered Points out of 1.00 Flag question Stephanie likes to party. She buys and drinks large amounts of alcohol. She is finding that the older she gets, the more forgetful she becomes. She often forgets to get up during the night to walk to the bathroom down the hall. So, her grandfather, who also likes to party, told her about this thing called a chamber pot, which she has named Harvey. She has had some success in using Harvey, but unfortunately still forgets to empty Harvey in the mornings before she goes to her 8 : 00 class. She has decided it is too much of a hassle to empty Harvey every morning. Last Thursday she was carrying Harvey and Harvey's contents to the dumpster at the back of her apartment near Turtle Pond. She turned around and saw her ex, who waved at her. She fought the urge to yell profanities and decided to wave back. Unfortunately, it was at that moment that she remembered she was still holding Harvey. Stephanie dropped Harvey. Harvey broke. Harvey spilled into Turtle Pond. What events most likely happened after this incident? Choose all that apply and only those that apply. a. Bacterial concentrations increased immediately and by a very large amount. b. Organic carbon decreased and later returned to normal. c. Dissolved oxygen decreased and took a long time to return to normal. d. Algae decreased slightly and then grew by a very large amount. e. BOD levels quickly increased and then returned to normal, but not as fast as cyanobacterial levels. f. Nitrate levels increased but not as much as ammonia levels..

Non-marine (live in water that is not seawater) diatoms are algae that require sunlight to photosynthesize. Some diatoms are planktonic (live near the water surface) while others are benthic (bottom dwelling, attached to rocks and gravel). Gwen, a graduate student, and her undergraduate assistant, Lance, cored a closed basin lake (no outlet) in eastern North Dakota to study how diatom floral assemblage changed over time and to infer how the climate or the environment of the region changed. Look at the simplified diatom diagram shown below and suggest how the climate, the environment, or some other factor(s) might have changed that are consistent with the data presented..

News Revlew 4: Continuous Process Improvement Program Upon successful completion of this assignment, students should be able to: - recognize the continuous process improvements model (CPIM) for managing projects, - construct the process quality matrix (PQM) and zone mapping, - use and interpret tools for business process analysis, and - implement continuous improvements through the process of making small, incremental improvements within a business in order to improve the quality of project products, services, and processes. Brief Description Today's fast- paced, high-change project environments, coupled with organizations where formal project management may not be its strong suit, are often short on the necessary upfront planning. 1. Search relevant project management news in the media on a distressed project in Canada or any location in North America and provide practical ideas and strategies for the prevention, behaviour detection, analysis, recovery, and control of the distressed projects, focusing on where the project is in relation to its original goals/targets, and realigning the project objectives. 2. Describe the continuous process improvements model as a way to improve the quality of project products, and to sustain a competitive position in fast-paced information-age industries..

Nick is a male who displays a rare mitochondrial disease. Nick's wife, Anne, is unaffected. Should they be concerned about having affected children? Yes. All children will definitely be affected. Yes. All daughters will definitely be affected, but sons will be unaffected. No. It is most likely that neither sons nor daughters will be affected. Yes. There is a possibility that both sons and daughters will be affected.

Objectives: In this lab, students will practice: 1. Stack with single link-list 2. Circular Link-list Introduction Implement a stack using singly linked list To implement a stack using singly linked list concept, all the singly linked list operations are performed based on Stack operations LIFO(last in first out) and with the help of that knowledge we are going to implement a stack using single linked list. Using singly linked lists, we implement stack by storing the information in the form of nodes and we need to follow the stack rules and implement using singly linked list nodes. So we need to follow a simple rule in the implementation of a stack which is last in first out and all the operations can be performed with the help of a top variable .Let us learn how to perform Pop, Push, Peek, Display operations in the following article. Page 2 of 5 A stack can be easily implemented using the linked list. In stack Implementation, a stack contains a top pointer. which is "head" of the stack where pushing and popping items happens at the head of the list. First node have null in link field and second node link have first node address in link field and so on and last node address in "top" pointer. The main advantage of using linked list over an arrays is that it is possible to implement a stack that can shrink or grow as much as needed. In using array will put a restriction to the maximum capacity of the array which can lead to stack overflow. Here each new node will be dynamically allocate. so overflow is not possible. Stack Operations: 1. push() : Insert a new element into stack i.e just inserting a new element at the beginning of the linked list. Page 3 of 5 2. pop() : Return top element of the Stack i.e simply deleting the first element from the linked list. 3. peek(): Return the top element. 4. display(): Print all elements in Stack. Circular linked list Introduction: Circular Linked List is a variation of Linked list in which the first element points to the last element and the last element points to the first element. Both Singly Linked List and Doubly Linked List can be made into a circular linked list. Singly Linked List as Circular In singly linked list, the next pointer of the last node points to the first node. Doubly Linked List as Circular In doubly linked list, the next pointer of the last node points to the first node and the previous pointer of the first node points to the last node making the circular in both directions. Question 1 1. Implement a template-based stack using a singly linked list. The required member methods are: int size(): returns the count of total element stored in the stack. bool isEmpty(): returns true if the stack is empty else false. bool top(T\&): returns, but does not delete, the topmost element from the stack via the parameter passed by reference. It returns false via a return statement if there is no element in the stack, else it returns true and assigns the top most element to the parameter passed by ref.
