Evolution questions: (please answer this in short) Q1. In what sense might thermodynamics actually promote the development of local order [hints, Ripples in a streamed; Dissipation driven organization] Background information for Q2. The platypus is an unusual mammal. it lays eggs like amphibians, reptiles, and birds, and it has hair and makes like other mammals. it also has some very distinctive features such as the ability to detect electric fields with its snout. the genome of the platypus was recently sequenced- an accomplishment that was described in the media with headlines like the other one below [ I can\'t attach the figure so here is the info for the tree: amphibian is out-group, on the first branch in ingroup, lizard, dinosaur and bird are monophyletic, where bird and dinosaur shared the most recent common ancestor. on the second branch, monophyletic, where platypus and other mammals shared common ancestor]. I don\'t think you even need the tree. Quuestion 2: from a tree thinking perspective, critique the idea that platypus are part bird, part mammal and part reptile. in particular, how would you describe the similarities that platypus uniquely share with other mammals (e.g. hair)? how does this differ from the similarities they share with birds (e.g. laying eggs? explain. Solution Question 1: Answer: Laws of thermodynamics 1st law: Also known as law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. 2nd law: It states that the state of entropy of the entire universe, as a closed isolated system, will always increase over time. It also states that the changes in the entropy in the universe can never be negative. Thermodynamics actually promote the development of local order. For example: If a creature could take, say, a kilogram of non-living, highly disordered material and turn it into a kilogram of highly ordered creature, then that would certainly be a big violation of the second law of thermodynamics. However, people (for example) consume along the lines of about 30 to 50 tons of food during the course of a lifetime. Some of that goes into building a fine and foxy body, but most of it goes into powering that body and fighting degradation (blood and skin and really everything wears out and needs to be replaced). So, about 0.15% (give or take) of that food matter is used to build a body, and 99.85% is used for power and to fight the entropy drop involved in body construction and temporarily holding back the horrifying ravages of time. Question 2: Answer: similarities that platypus uniquely share with other mammals a) making milk to having live-born young b) At roughly 2.2 billion base pairs, the platypus genome is about two-thirds the size of the human genome, the researchers found. It shares more than 80 percent of its genes with other mammals. c) Like humans, platypuses carry an X and a Y chromosome. But unlike humans, the X and Y are not sex chromosomes. d) The genome also includ.

Ethanol (CH3-CH2-OH) is miscible in water because it is able to form hydrogen bonds with itself and other molecules. However, its structure only allows it to form 1-2 hydrogen bonds. This is one reason why even low concentrations of ethanol in solution are lethal for cells. Based on this information, explain why we can use high concentrations ethanol to precipitate DNA out of solution. Also, describe predict the effects of increasing concentrations of ethanol in (and around) a cell on macro-molecular interactions (i.e. on weak bonds). Finally, it is possible to select for yeast that a tolerant to increased concentrations of ethanol. Give an example of a physiological change in yeast cells that might make them resistant to ethanol. Solution 1. DNA is a highly polar molecule as a result of which it is highly soluble in water. Due to its high polarity, the electrostatic forces between charged particles is much less in aqueous solution. There is formation of a shell by water molecules around charge particles. Ethanol is less polar and its addition disrupts the shell formed by water molecule around charged particles. As a result, there is ionic bond formation between phosphate groups of DNA and positively charged ions present in the solution. This causes precipitation of DNA. 2. Ethanol disrups the hydrogen bonds between water molecules. This alters the hydrophilic regions of the plasma membrane, thus altering their structure. There is a resultant dehydration of cells. 3. Upon exposure to ethanol, yeast produces high amounts of monounsaturated fatty acids in cellular lipids. This an be a method of developing ethanol tolerance in some strains of yeast..

Assembly Language Programming Using TI MSP430 and IAR Workbench. Write an assembly program that first initializes two 16-bit signed integers, A and B. Create a subroutine, called SW_MUL, that multiplies the two integers together using the multiplication technique of your choice. Parameters should be passed to the subroutine using the stack and the result stored in R14. A second subroutine, called HW_MUL, must then be created that multiplies the two integers using the hardware multiplier. The parameters should be passed using registers and the result should be stored in R15. Assess the performance of the subroutines by monitoring the clock cycle counter in the IAR Workbench. Thanks in advance for any help! Solution An assembly (or assembler) language,[1] often abbreviated asm, is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture\'s machine code instructions. Each assembly language is specific to a particular computer architecture. In contrast, most high-level programming languages are generally portable across multiple architectures but require interpretingor compiling. Assembly language may also be called symbolic machine code.[2] Assembly language is converted into executable machine code by a utility program referred to as an assembler. The conversion process is referred to as assembly, or assembling the source code. Assembly time is the computational step where an assembler is run..

Analyze the structure of the mobile technology industry. How has it evolved in recent years? Solution As a consumer technology, mobile communications has been quickly adopted by consumers. The structure of mobile technology starts with the mobile network infrastructure. It consists of towers which are used to transmit signals. Use of core technology like 2G, 3G and 4G is the base of the structure. The key players in the mobile technology industry\'s value chain are: innovators for the core communications technologies, component designers and manufacturers, original equipment manufacturers (OEMs), infrastructure suppliers, mobile network operators, content providers, mobile app developers, and device retailers. Evolution: Mobile technology started with basic serviceds of voice calls, then moved to SMS and now the use of applications (apps) is prominent on a global scale. These days there are apps for shopping, medical advice, weather, news, travle related apps. In terms of speed and core technology, the mobile users started with 2G, then moved to 3G. Many countries are now roling out the 4G technology. In terms of cost to the consumers, the figure has been falling constantly. In 2006, cost of data per megabyte was $8, which fell down to $1 in the year 2010. (source: Cisco). In terms of applicability, consumers these days use mobile technology for diverse activities like banking, holding mobile wallets, making video calls, etc. The applicability of moble technology, in its initial days was limited to calling and sending messages..

What are the leading current causes of extinction? Select any one of the causes you listed and find a specific example of an organism threatened by this cause. 100 words or more Solution Top causes of species extinction Natural causes include climatic changes such as climatic heating or cooling, change in sea level and currents, disease or epidemic, and in rare cases acid rain. Other Human causes incude habitat fragmentation, Agriculture, Human overpopulation, Deforestation and Hunting or poarching. Climatic changes causes temperatures to increase or decrease drastically which inturn impacts life of animals. Aquatic life is highly dependant on sea level, sea current and gases from volcanic activty change the composition of ocean water making aquatic life impossible in such water conditions. Disease/epidemic is another major cause for extinction. Due to some major diseases there have been continuous death of certain species eventually leading to extinction. Human causes of extinction have emerged recently which include events like deforestation, hunting/poarching, agriculture, habitat fragmentation and overpoplation. Habitat fragmentation is one of the leading causes of extinction, loss of habitat or animals finding destroyed homes either due to human activities or natural clamities is causing the survival to be difficult for animals and birds. Growing human population is another major cause of extinction. For example, florida panther, Loggerhead sea Turtle, , Atlantic blue fin tuna, Mississippi frog, polar bear, and Gulf sturgeon have been noted as being under serious threat due to mass human population growth. These animals are rapidly loosing their habitat due to human population increase which is increasing human activities and occupying free lands for human occupancy and use of forest resourses for human lives. Deforestation, which has reasons mainly related to money or people\'s needs have made many species homeless. Removing trees removes most of the canopy, which blocks sun’s rays and holds heat at night. Deforestation leads to increase in extreme temperatures causing harm to plants and animal species..
