Since 1942, Ernst Mayr defined \'species\' as populations that can reproduce with one another but not with other populations One problem with this definition is that it applies only to mammals, beds and raffles it does not apply to 90% of all Irving organisms The phylogenetic species concept is based on sexual reproduction descent from common ancestors The author of the article Can Zimmer, argues that the problem of defining microbial species is arbitrary and irrelevant important for public health The author Zimmer points out that there are only two valid definitions of species at least 26 current concepts of species For the sake of convenience, Darwin defined the term species as based on mutual fertility resemblance among individuals genetic mutations Solution 1 .

Which of the following statements is consistent with the assertion that protists are paraphyletic? Selected Answer: Protists are more closely related to each other than to other groups of eukaryotes. Answers: Protists are more closely related to each other than to other groups of eukaryotes. Protists all share a common set of traits. There is no common set of traits that define a protist. Protists are all more primitive than land plants and animals. Most cnidarians are known to produce toxins. In fact, it has been claimed that one particular species produces the most deadly of all toxins on the planet. What X feature of this group most likely evolved simultaneously with the evolution of these toxins? Selected Answer: Diploblastic design Answers: A slow-moving or sessile lifestyle in the adult Bilateral symmetry in the mobile larval forms The medusa body form Asexual reproduction Diploblastic design What group of fungi has the ability to penetrate its host's cell wall, thus increasing the efficiency with which materials are passed from fungus to host? Selected Answer: Ectomycorrhizal fungi Answers: Endophytes Arbuscular mycorrhizal fungi Ectomycorrhizal fungi Lichens.

Explain what factors underlying the signaling specificity and the specificity of the cellular response Solution Factors effecting on signalling specificity: Cell signalling is a very important process for basic activity of different cells and their communication between cells to perform any task. for basic growth and development it has a very important role. If there are error in signal processing and trunsduction then it can be responsible for different diseases, cancer, autoimmunity, diabetis etc. signalling can be extra cellular or it can be intracellular. Now transcriptional regulation like cyclic AMP is an important factor for cell signalling. now there are different factor effecting signal process which are: Intracrine signals that produce from a target cell which can stay within the target cells. Autocrine signals means which are producing by the target cell and also secreted, but also affect the target cell ownself via receptors. juxtacrine signals transmitted along cell memebrane via protein and lipid chain. Paracrine signals generally target different cells in the vicinity and those are called emitting cells. Now Endocrine signals target generally distant cells, it is so much important because it produces hormones and that hormones transfer into the body system through blood. cell- cell concact is also an important factor for cell signalling process. there are also gap junction that connect theit cytoplasomic connection. and these are all very much specific for perfect and identical cellular response..

What are the characteristics of life? Solution Answer: Chatacteristics of life: (1) Growth: All living organisms grow, but it is not the defining feature of organisms. It is because non living things, such as a sand dune can grow over time due to accumulation of more sand particles on it. Growth in living organisms are intrinsic (from inside) while those of non living things are extrinsic (from outside). More specifically, intrinsic growth is the defining feature of an organism. In unicellular organisms, growth and reproduction are synonymous. (2) Metabolism: All living organisms metabolise, that is they undergo varieties of biochemical reactions in the body, both to synthesize and degrade macromolecules. The sum total of the catabolic and anabolic processes in the body is called metabolism. It is the defining feature of living organisms. (3) Cellular organisation: All living organisms have cellular architecture, be it a multicelluar organism like humans or unicellular like a bacterium. The cell contains DNA which carries all the necessary informations to make the proteins required for carrying out biological functions. It is also a defining feature of living beings. (4) Reproduction: Living organisms are characterized by the ability to reproduce. But, it is not a defining feature of living organisms. For example, infertile couples, worker bees and mules cannot reproduce but are living. (5) Conciousness: This is another defining feature of living things. Conciousness is the ability of an organism to respond to changes in its environment, more specifically to external stimuli. Human beings are the only organisms to have self conciousness. (6) Energy: Living things take energy for their growth and functions. (7) Homeostasis: It is the process of maintaining a constant balance in the internal environment of the body and plays a crucial role in sustaining life..

three fossils are found in undisturbed layers of rock, or strata. Fossil A is closest to the earth surface. Given this limited data, what assumptions can you make about these fossils? Solution Ans. A fossil forms when a mud/sand/clay is deposited over a deceased organism overtime. In due course, more and more soil particles are deposited over the previous one, forming layers or strata. So, the recent (newest one) layer of soil remains at the top towards the earth surface, while the oldest layer (in which organism buried) lies at the bottom (farthest deep from earth surface). As a result, the dead organism faces gradually increasing high pressure due to deposition of additional strata. The soft parts decay first, the hard parts (say, bones) being impressed in the highly-compressed soil- thus forming fossils. With the limited information, it can be concluded that fossil A is the newest one (dies most recently) because it is present in the a strata closet to Earth surface..

Think about what you now know about project delivery systems. Are there any specific enhancements that could be made to the currently used project delivery systems to help them to better address the needs of stakeholders? As you prepare for this Discussion, consider how stakeholder needs may change in the future. With these thoughts in mind, respond to the following questions: In your opinion, how will current project delivery systems evolve to accommodate the changing needs of society? How may the increased use of technology shape future project delivery systems? Solution The design and construction industry continues to debate which project delivery system is best. Just pick up a trade magazine and you will often find an article addressing the selection of project delivery systems for a design and construction project. It is also common for project delivery systems to be a seminar topic. So what is the “best delivery system” for a design and construction project? The answer is IT DEPENDS! There is NO silver bullet! There is NO best system! The “best delivery system” debate is wrong and misses a great opportunity for the design and construction industry. Selection of the project delivery system should be based on specific project requirements, specific characteristics and circumstances of the owner, and the successful formulation of the project team. The real opportunity for design professionals and the construction industry is to help educate owners regarding the available project delivery systems, and then assist owners in selecting the best delivery system for the specific project and circumstance. Selection should always benefit the owner while at the same time promote a winning opportunity for all project participants. This paper is intended to present concepts and tools to help owners, design professionals, and the construction industry to select and set-up a “winning delivery system” for projects. This paper is divided into three areas and each of these areas is divided into three parts: •Three Primary Project Delivery Systems—All project delivery systems can be derived from three primary systems. •Three Key Project Delivery System Principles—These include the seven major roles required for all design and construction projects, the two types of agreements owners have with design and construction providers, and the allocation of risk for winning projects. •Three Key Areas of Consideration for Project Delivery System Selection—Selection should include project, owner, and team building considerations. Three Primary Project Delivery Systems There are several good publications available that address project delivery systems. Four that are particularly helpful include: •Client Advisor by The Associated General Contractors of Massachusetts (AGC) and The Boston Society of Architects (BSA). •Handbook on Project Delivery by The American Institute of Architects, California Council (AIACC). •Project Delivery Systems for Building Construction by A.

The brain stem is the link between what two parts? What two structures are part of the upper brain stem? Give the function of each part. What is the limbic system? What three structures are part of the lower brain stem? Give the function of each. Solution 1. The brain stem is the link between the brain and the spinal cord. 2.The upper brain part consists the mid brain and the pons. Functions of mid brain: Also called as the mesencephalon serves as a relay center for visual, auditory and motor information. It regulates the autonomic functions like digestion,heart rate and the respiratory rate. Pons It is the major structure of the upper brain and regulates two important functions. It controls the breathing rate and is also involved in the transmission of the signals to and from other parts of the brain like the cerebrum and the cerebellum.It is involved in the reguation of deep sleep and also sensations like hearing, taste and balance. 3.Limbic system refers to a complex system of nerves and networks in the brain located on both the sides of the thalamus immediately beneath the cerebrum and is concerned with the control of emotions and other related functions related to our instincts and memories..

She is standing in what is left of the Accounting Department wih Tony Martinez, the cost accountant. Requirement Determine the ending inventories of raw materials, work in process, and finished goods. Assume that Raw Materials Inventory contains only direct materials. I didn\'t know mud could smell so bad,\" Tony says. \"What should I be looking for? Don\'t worry about beginning inventory numbers,\" responds Marissa. \"We\'ll get them from last year\'s annual report. We need first-quarter cost data. Data Table \"I was working on the first-quarter results just before the storm hit,\" Tony says. \"Look, my report\'s still in my desk drawer. But acan make out is that for the first quarter, material purchases were $537,000 and that direct labor, manufacturing overhead (other than indirect materials), and total manufacturing costs to account for were $523,000; $190,000; and $1,504,000, respectively. Wait, and cost of goods available for sale was $1,570,000.\" Raw materials, $103,000 .Work in process, $214,000 Finished goods, $224,000 Great,\" says Marissa. \"I remember that sales for the period were approximately $1.6 million. Given our gross profit of 15%, that\'s all you should need.\" Tony is not sure about that, but decides to see what he can do with this information. He remembers several schedules he learned in college that may help him get started. PrintDone Print Done Solution.

Wizards are very useful for creating a good user experience. In all businesses, interactive sessions are most beneficial. To improve the user experience, wizards in Odoo provide an interactive session. For creating wizards, we can use transient models or abstract models. This gives features of a model class except the data storing. Transient and abstract models have permanent database persistence. For them, database tables are made, and the records in such tables are kept until they are specifically erased.

Since 1942, Ernst Mayr defined species as populations that can re.pdf

1. Since 1942, Ernst Mayr defined 'species' as populations that can reproduce with one another but not with other populations One problem with this definition is that it applies only to mammals, beds and raffles it does not apply to 90% of all Irving organisms The phylogenetic species concept is based on sexual reproduction descent from common ancestors The author of the article Can Zimmer, argues that the problem of defining microbial species is arbitrary and irrelevant important for public health The author Zimmer points out that there are only two valid definitions of species at least 26 current concepts of species For the sake of convenience, Darwin defined the term species as based on mutual fertility resemblance among individuals genetic mutations Solution 1 . Ootion A Ernst mayr's concept of species applies to only those organisms that can sexually reproduce. He did not mention or involve other organisms such as prokaryotes, plants, fungi , bacteria who undergo asexual reproduction. His idea of species was limited to birds, mammals and reptiles .
