Cell Phones with Wireless Connectivity essay Cell Phones with Wireless Connectivity essay Cell Phones with Wireless Connectivity essayThe problem considered in this paper is the choice of a cell phone with support of wireless technologies for business purposes.Description of possible solutionsThere are numerous smartphones with full-scale support of wireless technologies which can be used for business purposes. The choice of two key alternatives was done basing on the phones popularity and rating according to phone reviews. The alternatives include Apple iPhone 6 and Google Nexus 6. Purchasing any of these phones will help the buyer connect with a variety of wireless networks and get access to various data transmission technologies.The first alternative is purchasing Apple iPhone 6. This phones display size is 4.7 inches, the screen is built using IPS LCD technology, the phone operates using iOs 8x, has 128 Gb of built-in storage, 1024 MB RAM, dual-core 1.4 GHz Apple A8 processor (CNet, 2014). Wireless networks supported by this phone are CDMA, GSM, UMTS and FDD LTE (CNet , 2014). Wireless data transmission technologies embedded in this phone are HSPA, LTE category 4, GPRS, EDGE, HSUPA, EV-DO Rev. A and B (CNet, 2014).The device is capable of Wi-Fi positioning, has GPS, A-GPS, Cell ID and Glonass technologies for positioning. With regard to wireless connectivity options, this alternative has Bluetooth 4.0, Wi-Fi support a/b/g/n/, n for 5 GHz frequency and ac and NFC (CNet, 2014). Manufacturers suggested retail price of this phone is $849 (CNet, 2014). The device was released on September 9, 2014.The other solution is Google Nexus 6 phone. The characteristics of this device are the following. Display size is 6 inches, and display technology used for this device is AMOLED (CNet, 2014). Operating system used for the phone is Android 5.0 (CNet, 2014). The devices hardware includes 64 GB of built-in storage space, 3072 MB RAM, CPU used in this phone is quad-core 2.7 GHz Qualcomm Snapdragon (CNet, 2014). With regard to wireless networks/technologies, this phone supports GSM, UMTS, FDD LTE and TDD LTE (CNet, 2014).Data transmission technologies included in Nexus 6 are LTE-A, HDSPA and HDSPA+, HSUPA, GPRS and EDGE (CNet, 2014). The phone is capable of GPS and A-GPS positioning. Wireless connectivity functions supported by the device include Bluetooth 4.1, Wi-Fi a/b/g/n/n 5 GHz and ac, NFS and tethering (CNet, 2014). The device was announced on October 15, 2014. Retail price suggested by manufacturer is not known yet, but will soon be announced by Google.Criteria for measuring alternativesThere might be different phone selection criteria basing on the purposes of buying a phone and the tasks that will be completed using the phone. In the context of business use of cell phones with emphasis on wireless connectivity, the following criteria for choosing a smartphone can be used (Abbott, 2013).The range of wireless technologies and data transmission technologies supported by the phone.Since business people have to travel a lot and interact with various wireless networks, the range of technologies supported by the phone and the versions of these technologies are important. These technologies define the range of locations where the owner can use the phone and the speed of data transmission.Battery life.Active use of phone and data exchange with wireless networks will lead to quick battery discharging, so battery life is an important factor for business use.Operating system and related appsBusiness people are likely to perform a variety of automation, scheduling and other work-related tasks using their phones (Baldauf Stair, 2010). Convenience of the operating system and availability of business apps are important in this case.Price.It is desirable to choose a phone with optimal balance of price and functionality.Collaboration with wireless carriersThe choice of phone might depend on the existing bundling options. Most wireless carriers partner with phone manufacturers and offer attractive contract options (Baldauf Sta ir, 2010). The match between the best suitable carrier and mobile phone manufacturer might be an important criterion for choosing the phone.Process of conducting researchThe research will be conducted using websites and journals with technical characteristics of smartphones, smartphone reviews, offers of wireless carriers associated with the alternatives considered in the previous sections. Analysis of the match between operating system and business needs will be performed using a survey of key employees and comparing the results of the survey with other business reviews.

Mendels Law of Independent Assortment

Mendel's Law of Independent Assortment In the 1860s, a monk named Gregor Mendel discovered many of the principles that govern heredity. One of these principles, now known as Mendels law of independent assortment, states that allele pairs separate during the formation of gametes. This means that traits are transmitted to offspring independently of one another. Mendel discovered this principle after performing dihybrid crosses between plants that had two traits, such as seed color and pod color, that differed from one another. After these plants were allowed to self-pollinate, he noticed that the same ratio of 9:3:3:1 appeared among the offspring. Mendel concluded that traits were transmitted to offspring independently. The image above shows a true-breeding plant with the dominant traits of green pod color (GG) and yellow seed color (YY) being cross-pollinated with a true-breeding plant with yellow pod color (gg) and green seed color (yy). The resulting offspring are all heterozygous for green pod color and yellow seed color (GgYy). If the offspring are allowed to self pollinate, a 9:3:3:1 ratio will be seen in the next generation. About nine  plants will have green pods and yellow seeds, three will have green pods and green seeds, three will have yellow pods and yellow seeds, and one will have a yellow pod and green seeds. This distribution of traits of typical of dihybrid crosses. Mendel's Law of Segregation Foundational to the law of independent assortment is the law of segregation. Mendels earlier experiments led him to formulate this genetics principle. The law of segregation is based on four main concepts. The first is that genes exist in more than one form or allele. Secondly, organisms inherit two alleles (one from each parent) during sexual reproduction. Thirdly, these alleles separate during meiosis, leaving each gamete with one allele for a single trait. Finally, heterozygous alleles exhibit complete dominance, as one allele is dominant and the other is recessive. It is the segregation of alleles that allows for the independent transmission of traits. Non-Mendelian Inheritance Some patterns of inheritance do not exhibit regular Mendelian segregation patterns. In incomplete dominance, for example, one allele does not completely dominate the other. This results in a third phenotype that is a mixture of those observed in the parent alleles. An example of incomplete dominance can be seen in snapdragon plants. A red snapdragon plant that is cross-pollinated with a white snapdragon plant produces pink snapdragon offspring. In co-dominance, both alleles are fully expressed. This results in a third phenotype that displays distinct characteristics of both alleles. For example, when red tulips are crossed with white tulips, the resulting offspring sometimes have flowers that are both red and white. While most genes contain two allele forms, some have multiple alleles for a trait. A common example of this in humans is ABO blood type. ABO blood types have three alleles, which are represented as (IA, IB, IO). Some traits are polygenic, which means that they are controlled by more than one gene. These genes may have two or more alleles for a specific trait. Polygenic traits have many possible phenotypes. Examples of such traits include skin color and eye color.
