The theory of evolution, describes the human social dynamics and provides a significant support to the study of parenting (Geary and Flinn, 2001). Central to the evolutionary approach, are the differences between the characteristics of men and women, and their functions. Thus, the theory of evolution provides a valid framework for understanding different aspects of childrearing. Next to parenting and the differences between men and women, anxiety can also be approached from an evolutionary…

Society, will be altered by genetic engineering. Designing the perfect baby seems like a fantastic idea. If one family does it, it is an excellent idea. If every family in the world designed their children this procedure would not be as impressive. The side effect for a production of a massive amount of perfect human beings is unknown. There are many different outcomes. Human society may lose their sense of individuality. If one family creates the “perfect” human, everyone else would want to…

In conservation biology, it is one of the main goals to determine MVP (minimum viable population) and reserve size. These estimates that are produced via simulation, are valuable in the sense as grizzly populations are often endangered or threatened, and their population has been declining for a number of years (Wielgus, 2001). Although the population is declining, it is still legal in North America to hunt these endangered species, as trophy hunting and is believed to be beneficial or…

Use quadrats to estimate the size of a population in an ecosystem Collect, analyse and present data to describe the distribution of species whose abundance has been estimated Consider the accuracy of population estimation strategies Identify factors determining the distribution of species whose abundance has been estimated Examine trends in population estimates for some plant and animal species in each environment Examine trends in population…

Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

How do scientists explain and support the argument for biological evolution? From the recent trip to the Minnesota Zoo, labs performed in class and multiple readings these things have shown students the dynamics of evolution. Scientists, like Charles Darwin, who have focused studies on certain organisms like the Galapagos Island finches have played a large role in our knowledge today about biological evolution, natural selection and descent with modification. Over many generations and an…

Introduction Women currently hold roughly 25% of STEM (Science, Technology, Engineering and Mathematics) jobs in the United States, despite a roughly equal representation in the workplace as a whole (Beede 2011). It seems as though our society has accepted the presence of women in the workplace, on the condition that women only occupy jobs deemed suitable for their gender. Harvard president Lawrence H. Summers made a speech in January of 2005, claiming that the reason women are…

Safety in the science classroom involves weighing the potential risk factors of an experiment against the educational value, teacher and student should have a full understanding all the potential hazards of the materials, the experiment, and the equipment used. Safety concerns and potential hazards should be addressed prior to engaging in any laboratory activity and documented in the lesson plan. Students should be aware of the emergency contact sheet with phone numbers that is attached to the…

Population. Population, biologically defined as the summation of members of a particular species or group within a set region or community. For mankind, population has been the double edged sword and, the blunt shield that have allowed humanity to dominate this flying space-rock known as Earth. The population avaliable to a society meant the amount of workers which can gather, use, and produce various resources. This combined with the ability of humanity to use tools and technology, allowed…

What is animal testing used for and why? Animal testing is used and required by the United States government to test the safety of drugs, chemicals, cosmetics, and various consumer products. Additionally, animals are commonly used in the practice of medical and military training. Government agencies that heavily rely on animal testing are the U.S. Military, the U.S. Environmental Protection Agency (EPA) , the Food and Drug Administration (FDA), the Department of Transportation (DOT), and the…
