_solve http://www.theguardian.com/science/2013/sep/01/20-big-questions-in-science Research 2 examples of questions that science cannot yet answer and suggest why scientists are unable to answer these questions
One question that scientists cannot yet answer is the cure for cancer. They cannot find a cure mainly because cancer is not a single disease; it’s a loose group of any hundreds of diseases. Not every cancer cell is the same so there are multiple levels of difficulty. Other reason scientists cannot yet cure cancer is because they are limited of recourses because of the lack of funding, if they had enough funding to research more into this disease.
Another question that science is still trying to answer is the cure for hiv/aids. The main reason that scientists have not been able to cure this disease yet is because they don’t have the level of technology to do that yet. They can only alter a few cells a day but the human body consists of trillions of cells. Therefore until they discover technology to this level the chances of finding a cure for hiv/aids is very low.
Research 2 examples of questions that science will probably never be able to answer

A question that science cannot answer is how life began on earth. Scientists cannot be certain as to how life began mainly because no one was around at that time to be certain what happened so scientists have to just make educated guesses based on the evidence they can find from the beginning of the planet. Most of this is microscopic since it is strongly believed among scientists

known as micro-organisms. They are usually a few micrometers in length and normally exist together in millions. They come in 3 main shapes: Spherical, Rod Shaped and Spiral and can be found everywhere. There are approximately 10 times as many bacterial cells in the human body then human cells, and a lot of these are found lining the digestive system. Some types of bacteria are useful for production of foods such as yoghurt. The cell structure is simpler than that of other organisms as there is no…

Evolution of Microbes Essay

Microbes Microorganisms – Organisms and acellular biological entities too small to be seen clearly by the unaided eye. Cellular microbes are found in plants and animals. Prokaryotic cells lack a nucleus unlike eukaryotic cells. Eukaryotic cells have membrane enclosed nuclei and are more complex and larger than prokaryotes. Organisms are divided into five kingdoms: Monera – Prokaryotes are places in this kindgom Protista Fungi Animalia Plantae *This classification system is no longer…

so that each new daughter cell gets a complete copy of genetic information. Asexual Reproduction -The production of genetically identical offspring from a single parent is known as asexual reproduction. -For many single-celled organisms, cell division is the only form of reproduction. -It many also occur in multicellular organisms by the process of budding. Sexual Reproduction -In sexual reproduction, offspring are produced by the fusion of special reproductive cells formed by each of…

being the strongest base. If a liquid has a pH of 7, it's neutral. This would be something like distilled water. 3. Adaptations also called an adaptive trait, in biology is a trait with a current functional role in the life history of an organism that is maintained andevolved by means of natural selection. Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation. Adaptations contribute to the fitness and survival of…

statistical tests to determine the extent chance has influenced the data. Variation is the result of two main factors: genetic differences and environmental influences. Genetic differences These are due to the different genes that each individual organism possessed. These change from generation to generation. Genetic variation occurs as a result of: Mutations: These sudden changes to genes and chromosomes may be passed to the next generation. Meiosis: This form of nuclear division forms the gametes…
