Every society in the world has found the need to count, whether how many fish they had caught or the number of family members; therefore, each culture throughout the millennia have come of with numeration systems to do so. For example the Mayan numeration system dates back to 9000 BC and were able to create sophisticated calendars—one of which supposedly marked the end of the world (Aufmann et al). They system was based on the solar calendar. Another example of a society developing a numeration system

Chapter four was on the Genes, DNA, chromosomes are what makes you who you are there the settlement structure that is giving to you by your farther and mother. these instructions are in the cells. Remember all living organism are made up of cells there are many different types like nervous cells, hair cells and skin cell. They all also have different shapes and forms. But every cells has the same basic parts the cells has an outer boarder call the membrane which we spoke about in chapter one. And

We often connect ourselves to the world through our appearances. One of the first characteristics we notice about another human is the color of their skin. It is unavoidable, as the largest organ of the body, it covers and highlights our individual features and forms a protective wall against the elements. There is no escape from the social repercussions our pigmentation causes no matter what range of the very broad spectrum of color we fall into. I have never thought so much about the genetic and

genome with thousands of duplicate genes and regulatory elements, all of which are subject to unique evolutionary forces. Immediately after duplication, all regions of the genome are nearly identical. However, depending on the selection acting on the gene, the duplicated copy could result in a number of different fates. If there is strong purifying selection on the gene, all copies would retain the initial function, but under other circumstances, the duplicated genes could develop a new function, divide

Epigenetics studies the process where a gene is chemically altered based on an environmental factor, but this alteration affects how the DNA is expressed, without affecting the actual sequence of the DNA (Hughes, 2014). Epigenetics is the study of these heritable changes within a particular gene’s function. So in other words, once a change occurs at the genome level, a change to DNA occurs and can be passed down from one generation to another, thus the gene functions differently as a result of the

Penicillin was discovered by accident in 1928 by Alexander Fleming. After leaving bacteria containing Petri dishes in a lab over a weekend they became contaminated with mould. Alexander Fleming realised that the bacteria calls around the mould were dying. It was through further testing that he realised the mould was creating a substance that destroyed bacteria, which he later called Penicillin. Structure of Penicillin Penicillin G is a naturally occurring penicillin that works against gram-positive

Drug interaction is a common phenomenon, that impairs or exaggerates the proposed effect of one or both administered drugs. Therefore, researchers should pay attention to this problem so as to elucidate possible interactions between different drugs when it deemed necessary to coadminister them. An example of combination between antibiotics and anthelmintic drugs that may be used in veterinary medicine is the coadministration of cephalosporin and nitroxynil. Cefoperazone is a semi-synthetic third

Camouflage Frogs Introduction Natural selection is the process where an environmental factor acts upon a population and results in some organisms having more offspring then others. This is widely accepted as the cause of evolution, and the reason that populations develop and change into better individuals over time allowing their species to maximise their chances of survival and develop into a more dynamic population. One of the many types of genetic variation is camouflage. The natural colouring

Most Healthy people won’t want this implant because it would probably involve a doctor opening your skull to place this device. In today age, the people who would probably use this if they have a serious medical condition that could help them with the use of it. Society could benefit from this because it allows anyone to connect to anyone in the world. But at the moment Phones can do all this and are much cheaper to have then having surgery to have implant put in. In the future it would probably

recombinant frequencies between genes, table 4, was used to determine the gene distance. The recombinant frequency was determined by counting the number of individuals whose genes differed from that of the parental type. For example, how many individuals white eye gene, and miniature wing gene, differed from both wild-type or both mutants. Recombination occurred between the white and miniature gene 33 times. Recombination occurred between the miniature and the forked genes 31 times. Recombination occurred
