continue to pass on those genes. Over time, more bacteria will contain DNA with genes allowing them to resist antibiotics and continue to reproduce. Because mutations do occur, it is possible to mutate genes to make them more or less fit for survival. Evolution / development does not occur in an

The U.S. environmental law that I choose is Endangered Species Act. This Act was passed in 1973, to protect the extinction of or threatened species. Before I go any further let me define the difference between extinct and threatened species; • Extinction is the process by which a species die out, this means that all genetic buildup of that species is gone forever. Extinction can be the cause of Natural disaster, from human activities. • Threatened species are living organism that can become endangered

The earth is the motherland of human society but the surface of the mother earth astro-geographically is not the same everywhere. A part of it is astro-geographically blessed with six eco-friendly seasons in a year; its other parts

Three indices were used for the analysis of abundance and diversity of the collected periphyton. The Shannon’s diversity index (H) (Shannon & Wiener, 1949) is a diversity index that is used to characterize species or genera diversity and account for their abundance and even the evenness. A high value of H would represent a diverse and equally distributed community and lower values would represent the opposite. A value of 0 would represent a community with just one species. Based on the periphyton

1970’s, plate tectonics is the scientific theory first proposed and elaborated by scientist, Alfred Wegener in 1912. The theory explains that the lithosphere is divided up into multiple plates that are moving constantly. (Cloos, 2018). This theory is regularly being adapted and developed as it has been through the past 400 years by several scientists. At first scientists, including Wegener only compiled a small amount of evidence supporting this theory. However, scientists have now composed a more

Title: Name: Instructors Name: Course Title: Date: Genetic Engineering Genetic engineering is a type of technology that changes the genetic structure of cells. The process entails the transfer of genes within and across species boundaries to improve the organisms. There is complex manipulation of biological chemicals and genetic materials during the process (Berlatsky, 2013). The chemical blueprints that determine an organism character are genes. Transferring the genes from one organism to

Molecular genetics is the field of biology and genetics that studies the structure and function of genes at a molecular level. Molecular genetics employs the methods of genetics and molecular biology to elucidate molecular function and interactions among genes. It is so called to differentiate it from other sub fields of genetics such as ecological genetics and population genetics. Genetically modified crops (GMCs, GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been

Home Reaction Paper of the movie entitled Home The film home by Yann Arthus-Bertrand is a beautifully shot panorama of the Earth and the damage done to it by modern humanity. It includes a moving narration about the evolution of the Earth, nature, agriculture, humans, and the crises of habitat destruction, energy depletion, climate disruption, degradation...of the environment, health, economic disparity, and more. The movie starts by taking the viewer back to the beginning of time, and explains

The following discussion will take into consideration the concept of genetic diversity, how it is introduced into a population and what, if any, are the resulting factors. The four means of introduction are: • Migration • Mutation • Population Size • Sexual Reproduction In the following synopsis, each means of introduction will be considered separately followed by a conclusion of the assignment. Migration as it relates to Genetic Diversity Migration is defined as the movement
