* Differentiate between hazard and a risk. Hazard is anything that causes injury‚ disease‚ or death to humans‚ or damage to personal or public property‚ or deterioration or destruction of environmental components. Risk is suffering injury disease‚ death‚ or some other loss as a result of exposure to a hazard. (Boorse) * What risks from Figure 17-16 and Table 17-3 surprise you and why do they surprise you? In figure 17-3 the aids rate is what surprised me I didn’t think it would be that low. If

In prokaryotes‚ it’s easier to make DNA replication because of the lack of a nucleus‚ but to do DNA replication in a eukaryotic cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts

Prokaryotic and eukaryotic cells are both vital to our world today. Prokaryotic cells are simple‚ yet the oldest‚ and were known to evolve around 3.5 billion year ago. Eukaryotic cells are more complex and have been said to appear on Earth 2.5 billion years ago. It is sort of like people or characters in movies. You see them one year and basically understand what they’re doing or going through and then a year or two from now they seem like they become more complicated to understand. That’s just

human life‚ stem cell research is helpful and effective due to the various diseases it has the potential to cure and the reduced risk of transplantation after surgery. Stem cells are versatile cells that have potential to develop into specific cells. Everyone has stem cells‚ however‚ they are much more dominant in a fetus than in an adult body. Stem cells have potential to create all specific cells in the body and repair or replace damaged cells. Stem cell research is important in society today for

Functionally‚ eukaryotic genomes can be described as much larger and more complex than prokaryotic genomes. This means regulation is a lot more demanding and intensive within the eukaryotic genome. Due to its complex nature‚ eukaryotic gene regulation can bring genetic changes in its product that affect gene expression‚ phenotypic outlook‚ and advances in biotechnology. This can be thought of as an evolutionary advantage to organisms in an unstable environment. Gene regulation in eukaryotes is a

Stem cells are cells in living organisms are able to adapt to become specialized cell types. They can split apart and regenerate‚ which is an incredibly useful mechanism in our bodies because it allows us to grow and heal. Stem cell research has allowed medical breakthroughs to fight malignant and nonmalignant diseases and ailments. Stem cells are able to create tissue and organs. By researching stem cells‚ we can continue use them to our advantage. They prove very beneficial in treating medical

All living organisms are composed of one or more cells‚ and like any living organism‚ cells are made up of smaller structures that help them function. In the context of cells‚ these smaller structures are referred to as organelles and each organelle has its own unique function that has developed over time. While we are typically aware of how these organelles function‚ how they evolved raises several questions. The main model for how eukaryotic cells evolved over time is the endosymbiont theory. This

Are stem cells important to medical research? The most basic cells in the human body are stem cells and people are formed from stem cells. Stem cells are an important part of human medical research‚ and they help with specific medical treatments. However‚ with all the good from stem cells‚ controversy surrounds the methods employed to obtain stem cells. Even with all the controversy‚ stem cells are useful. Stem cells are the most basic‚ but useful cells in the human body. They are the building

103 Stem cells are known as the foundation of our bodies‚ and without them we would be unable to repair various organs or tissues whenever they may become damaged. Stem cells are very extraordinary cells because after division and a new cell is created‚ they are able to either remain a stem cell or turn into an even more specialized cell such as a muscle cell‚ red blood cell‚ or brain cell. Until recently‚ there were only two major types of stem cells‚ known as embryonic stem cells and adult stem
