1. Review the four principles of sex-linked inheritance listed just before the case study.
Which individuals in figure 5.2 demonstrate principle 1?
Terry, Greg, Jenny and Bill 2. Which individuals in figure 5.2 represent principle
2?
Greg, Carl and Terry

3. Which individuals in figure 5.2 represent principle
3?
Jessica, Terry, Florence and Greg

4. Why are none of the males in figure 5.2 shown as carriers of hemophilia?

If the male has an X, then he has the disease. A male can’t carry hemophilia due to them
Only having a single X chromosome and hemophilia is an X-linked disease.

5. What is the probability that Marcy and Tom will have any child with hemophilia (irrespective of sex)? Show how you calculate this.
The total probability would be 12.5%.
This is calculated by marcy having 50% chance of a carrier(0.5).Tom is not a carrier(0).
So the children would have a 25% chance which is 50% of Marcy’s 50%.(0.5).
Calculation is* (.5)(.5)(.5)=.125 =12.5%

6. Suppose Marcy becomes pregnant and has an amniocentesis, a prenatal cell-sampling technique that can identify the sex of a child (among other things). She finds that she is going to have a baby girl. Should she be worried that the baby will have hemophilia? Why or why not? Suppose she decides to be sterilized after her baby’s birth, so she will have only this one child. Should she be concerned that her grandchildren will have hemophilia? Why or why not?
I don’t think she should worry. She herself has a 50% of being a carrier and Tom is
Not a carrier. Therefore the chances of her daughter having hemophilia is low.

7. Blood typing can help determine paternity.
Suppose an unmarried woman gives birth, charges a certain man with being the father, and sues for child support. He demands blood tests, which show that the woman is type A, the baby is type
A, and he is type B. Does this evidence rule him out as the father? Explain why or why not.

8. The drugs for cancer chemotherapy target rapidly dividing tumor cells, but also any other cells in the body that undergo rapid mitosis. In light of this, explain why these drugs often cause hair loss as a side effect.

9. Based on the data in table 5.1, which type of cancer—colon or oral—do you think is more treatable (has the better prognosis)? Explain your reasoning.…...

Bio Fuel

...(8) Many experts today believe that bio-fuel production causes more problems than it solves. Describe the main reasoning behind this view. · Bio-fuel production causes loss of tropical forest and other natural habitats, depletes oil, accelerates climate change, and exacerbates world hunger. · To grow biofuel crops, there needs to be cutting and burning of forests · You need burning of oil based fuel and use of petroleum based fertilizers to grow biofuel crops which leads to less oil which leads to a new for more biofuel so you burn all the forests and you need the oil to regrow them again · Deforestation – especially in South America and Indonesia accounts for 20% of all carbon emissions · Farming biofuels produces nitrous oxide which is bad for climate change · Large scale burning and cutting to grow crops –including biofuel crops- also causes adjacent forest decline: it causes reduced transpiration and hence reduced rainfall in adjacent forest areas result in drought cycle which accelerated death of trees which further reduces transpiration and rainfall. The accelerated death of trees results in warming of forest floor and accelerated decomposition of soil organic matter and explosion of termite population son dead tree trunks and branches. Both of this releases huge quantities of methane and carbon dioxide · The use of biodiesel from algae is not as green as it seems. It can generate four times the greenhouse emissions from regular...

Bios

...Video Summary BIOS One of the most common uses of Flash memory is for the basic input/out put system of you computer, commonly known as the BIOS. The BIOS makes sure all other chips, hard drives, ports and CPU function together. BIOS is the first program that is activated during the boot, running on ROM, ready only memory. Start up BIOS activates the POST bootstrap loader which runs POST. POST checks the basic system hardware testing memory and assigning system resources. Startup BIOS also check the CMOS, comparing them to the hardware found during POST. CMOS setting are stored in the RAM ( Random Access Memory) and are not permanent as BIOS setting are and can be changed by the user. BOIS and CMOS are different they are stored on different chips. BIOS are stored in ROM and CMOS are stored in RAM. BIOS are permanent, while CMOS are volatile, it can be erased if the power goes off. BIOS cannot be edited by users. CMOS can be edited by users, configuration can be saved. CMOS setting are not lost because of the CMOS battery, providing power during shutdown. Preserves CMOS configuration stored in RAM. If the battery dies the symptoms would be low battery= slow clock, dead battery which means checksum error during boot. The system will reboot once you clear the checksum error. After POST is complete and the CMOS are checked, the BIOS check the MBR (Master Boot Record), which is located on the first sector on the hard drive. MBR finds the activate partition and loads the......

Bios for Beginners

...OS Class – Toms Hardware Essay – 02-15-14 BIOS For Beginners “BIOS for Beginners” explains just how essential the BIOS is for any standard personal computer built today. The BIOS which stands for the Basic Input Output System is a chip installed directly on the motherboard and acts as the middle man that gives commands between the hardware and the operating system. Having incorrect settings on the BIOS can slow your computer down nearly in half which is why it is so important as a technician to understand how it works and the importance of each function it provides. As processors advance, the more complex the BIOS becomes as well often leaving even experienced computer technicians scratching their heads. Any wrong move when altering settings can lead to your computer malfunctioning. If this happens, you may need to completely reset the BIOS to the factory settings using the jumpers built in on the motherboard. “It is recommended that you reboot after each individual BIOS setting change to ensure that your system functions normally. If you make numerous changes before rebooting, and your system will no longer boot, you won't know which change is responsible for the failure,” http://www.tomshardware.com/reviews/bios-beginners,1126.html. To enter the BIOS in most computers, you will be using the F1, F2 or DEL button to enter the system. However, there are sometimes a couple other options as well given from a list of options when accessing damages and repairing the......

...his father who taught them about music. His sister played the keyboard and was quite good, but at the age of four years old Mozart outshined her. It was at a young age his father could tell he was meant to be a great musician and composer. His father was not only a musical teacher, but was an educated man as well and so naturally his father taught Mozart, and so it was that he was further along in his education than most boys his age, but for Mozart music was his passion, love, main interest. (Funk & Wagnalls New World) Amadeus was such a talented man that he was able to play the violin and harpsichord by the age of four, and a year later he was composing music. At age six Wolfgang went on his first tour escorted by his family. (Bio. A&E Television) The majority of his younger life was spent touring, and it was during this time he met Johann Sebastian Bach who was a great influence to Wolfgang, as well as Josef Mysliveček, Giovanni Battista Martini. It was during this time in 1770 that Mozart wrote an opera called Mitridate, re di Ponto, he also wrote the motet Exsultate, jubilate, K. 165, toward the end of his time in Italy which led to more commissions for him. Upon returning to Salzburg Mozart became the court musician for Prince-Archbishop Hieronymus Colloredo. During his tenure at the court he had the chance to work many different types of music, but it was during this time he found he enjoyed violins, so it was that he wrote five violin concertos, but......

Find a media piece—article, video, presentation, song, or other that recognizes the fundamental concepts of chemistry in biology. Include a link or reference citation for the piece and describe how it helped you better understand how fundamental concepts of chemistry affect biology. After my research at www.infoplease.com it has helped me to understand how fundamental concepts of chemistry affects biology by breaking down the concept of why chemistry and biology goes hand in hand. Infoplease, (2000-2014), stated that biology explained the living parts of the world and their environment. It also said that biology requires a little knowledge of chemistry and that it is important to know aspects of chemistry to make biology come alive. We all know that the understanding of chemistry requires a little mathematic but it is not important to go into detailed mathematical applications to understand the principles of biology.

Finally, carbon negative fuels, these fuels will also absorb carbon dioxide when they grow as well as carbon neutral fuels, but the difference is when carbon negative fuels burn and used as fuel, not the same amount of carbon dioxide which absorb when they grow will release, they tend to release small amount into the atmosphere. In other words, these fuels can reduce carbon dioxide (Mathew, 2008). Diagram source: http://biopact.com/2007/10/strange-world-of-carbon-negative.html. Convenience Biofuels is convenience because it does not require changes to switch to use compare with the other renewable energy, for example, solar energy and wind energy. (Want to know it, 2010). For the transport vehicle, Use of bio-diesel and bio-petrol do not require any change in the vehicle engine (Times internet limit, 2008). 3. Disadvantages Soil degradation The more alternative energy sources, for example biofuels, the greater the demand of agricultural land. Such as Amazon basin, scientist predicted deforestation will escalate, with growing amounts of virgin rainforest being cleared for farmland, thus greater soil degradation are going to ensue (Charles et al).

Bios and Post

...and Logic Understanding The BIOS and POST Student Name Introduction Inside every PC is a BIOS, which stands for Basic Input Output System.  In a nutshell, BIOS is software that interacts between a computer’s hardware and the operating system and software applications.  There are several types of BIOS', ranging from the motherboard ROM BIOS to adapter BIOS' such as video BIOS, drive controller BIOS, network adapter BIOS, SCSI adapter BIOS, etc... These BIOS' are the lowest level of software in a computer providing a set of small programs or software routines that allow the hardware of a computer to interact with the operating system by a set standard. The Boot Process To get to the operating system, a computer must first boot from the BIOS.  The BIOS performs a number of tasks when a computer is started.  From initializing the microprocessor to initializing and testing hardware to starting the operating system.  Starting a computer is not a simple task.  It's a methodical process that is performed every time power is applied to a computer. This process will vary with different computers and different BIOS', but the overall goal is the same. When you first turn on a computer the very first operation performed by the CPU is to read the address space at FFFF:0000h. This address space is only 16 bytes, which is not nearly enough space to house the BIOS found on a motherboard.  Instead, this location contains a special......

...Nonvolatile BIOS memory - CMOS [pic] CMOS Battery in a Pico ITX motherboard Non-volatile BIOS memory refers to the memory on a personal computer motherboard containing BIOS settings and sometimes the code used to initialize the computer and load the operating system. The non-volatile memory was historically called CMOS RAM or just CMOS because it traditionally used a low-power CMOS memory chip (the Motorola MC146818, or one of its higher-capacity clones), which was powered by a small battery when the system power was off. The term remains in wide use in this context, but has also grown into a misnomer. The non-volatile BIOS storage in contemporary computers might be in an EEPROM or flash memory chip and not in a volatile CMOS RAM. In these cases, the battery back-up is meant to keep the RTC chip synchronized. The NVRAM normally has a storage capacity of 512 Bytes, which is enough for all BIOS-settings. CMOS mismatch CMOS mismatch errors typically occur if the computer's power-on self-test program: 1. Finds a device that is not recorded in the CMOS. 2. Does not find a device that is recorded in the CMOS. 3. Finds a device that has different settings than those recorded for it in CMOS. 4. Detects a CMOS checksum error.

...Introduction To sum of the differences between ROM RAM BIOS and Post I will simply define the basis of each component while defining what they do. ROM is short for (Read-only Memory) Memory which data is prerecorded on a computer. ROM is simply data that cannot be eliminated even when the computer is off. When working in ROM it is difficult or nearly impossible to change. BIOS is short for the acronym (Basic Input Output System) it is a program which stores detailed information and enable the computer to boot. In addition a ROM chip located on the motherboard, it lets you access the basic setup and ensures that the BIOS will readily be available and will not de damaged by disk failures. RAM is (Random Access Memory) Memory that can be access randomly memory that can be access without touching preceding bytes. RAM is the typical memory found in most computers or printers. In addition, RAM is a volatile memory that requires power to keep information accessible. If power is lost, then memory can be lost. Lastly Post is the self-test which is activated by Bios. The post is designed to run checks on the motherboard. It necessary to use ROM for the BIOS because the ROM retains information on the computer even while shut down whereas RAM does not. Whenever a computer is being use the information is being stored on the RAM if the is ever a power shortage or the computer lose power the information is lost. RAM does not store memory when there is no power. POST beep codes make...

Bio-Medicine

...in need of provision. It can be explained that health and illness are simply biological descriptions of the state of our bodies. The structures of the body have been mapped out through genetics. This is ever closer inspection of the body or as Foucault 1977 would suggest through this ‘medical gaze’ which has brought considerable power to the medical profession. The sociology of health and illness is concerned with the social origins of and influence on disease rather than exploring its organic manifestation in individual bodies. The sociology of medicine is concerned with exploring the social, historical and cultural reasons for the rise of medicine particularly the bio-medicine model in the definition and treatment of illness. A more refined version of this common sense view underlies the long standing bio-medical model of disease based on the following assumptions. Firstly that disease is an organic condition and non-organic factors associated with the human mind are considered unimportant or are ignored altogether in the search for biological causes of pathological symptoms. Secondly that disease is a temporarily an organic state that can be eradicated and cured by medical intervention. Disease is experienced by a sick individual who then becomes the object of treatment. Disease is therefore treated after the symptoms appear and the application of medicine is a reactive healing process. It I treated in a medical environment in a surgery or hospital away from the site......
