Archaeological and bone chemistry evidence Study Questions 6 Archaeological and bone chemistry evidence indicate that Paranthropus robustus (and likely boisei as well) ate some meat. However, their huge check teeth suggest that they had evolved to depend primarily on some other dietary source. Considering that these Paranthropine species likely had similar dietary restrictions as other hominins (they likely couldn’t eat grass, for example), what sort of diet would you postulate they followed and what sort of environmental conditions would this reflect? robustus is believed to have a dental formula composed of enormous cheek teeth and a very thick enamel. P. robustus chewed food using the back of the jaw. Additionally, the cheekbones of P. robustus were large and this characteristic allowed the passage of food through the huge chewing muscles to the jaws. It is this vital characteristic that gave P. robustus a broad shaped -face. More so, P. robustus had an elongated sagittal crest which was useful for accommodating the huge muscles due to the large surface area needed to chew food. As a result of these large muscles,…

Describe your chosen ecological system. Yellowstone ecosystem is best known as a national park. It has several attractive sites. Many beautiful mountains are covered by expansive forests, stunning waterways, and enormous waterfalls. The geothermal pools and springs dot the scene making the place one of the most remarkable ecosystems. The main predators and herbivores The main predators include the wolves, the bear, wolverines, and the coyotes. Plants herbivores eat. The major herbivores found in the park include the moose, bison, elk mountain goats, and deer. Plants herbivores eat The main plants in the Yellowstone that herbivores eat include the deciduous species, several trees such as the pine, and both the white and Engelmann spruce. Other organisms that rely on those same plants to survive. Other organisms that depend on plants to survive include the birds and insects. [Editor1] An example of bird species found in Yellowstone is the woodpeckers, which belong to the Picidae family. Their foods are basically found on the barks of trees, which the bird obtains by hammering their peaks to extract insects. Woodpeckers may have black,…

Batch experiment studies on bio-sorption of Pb(II) and Cu(II) metal ions using low cost adsorbents from Prosopis Juliflora Bark and leaves.                                                                                                                   ABSTRACT Different heavy metals such as Lead (Pb), Cadmium (Cd), Copper (Cu), Chromium (Cr), Mercury (Hg), Zinc (Zn) and Arsenic (As) are the core elements used as colour pigments in textile industries. This is widely effecting the aquatic environment causing high increase of metallic substances in water resources, which is a threat for the environment and human health. Among different processes adsorption by activated carbon is an efficient process to remove heavy metals from waste water.  Research is being done on inventing different low cost adsorbents from different agricultural wastes that can be used effectively to remove different heavy metals from textile waste water.  My work discuss about the efficiency of removing heavy metals such as copper and lead by using activated carbon from Prosopis Juliflora bark and leaves. Prosopis Juliflora is widely known for the extensive property of absorbing water and certain heavy metals.  Activated carbon was formed from Prosopis juliflora bark and Prosopis Juliflora leaves…

Is Spec Work Evil?             Collaboration is essential in creating the best agency-client relationships. It helps the agency in forming a deep understanding of its goals and the brand. Now considering spec work in advertising, when the agency produces creative without insights of its audience and its brand’s challenges, the brand is used to determine whether the agency has the right team to solve problems and create effective communication with its audience (Oetting, 2015). Over time, spec work has been a point of dispute between agencies and clients. Beyond the increasing queries on whether or not the exercise is ethical or fair, spec advertising is a growing cost in business with lessening margins. The efforts made by most companies to use online design contests and crowdsourcing have caused the spec work to even get worse with time. Therefore, I think the spec process should be eliminated in the industry. Spec work is more of a guessing game since it’s rare for spec ideas to be produced. Also, the spec process is artificially guarded with little collaboration and minimal information provided.…

  Best Cheap Dab Rigs for 2020 All of us had a chemistry course in our lives, which felt useless and dreary when we studied it. A thought always crossed our minds that what’s the use of it in the practical experience? Well, let’s put our chemistry to test and use beakers and glass apparatus to bring out the scientist within ourselves. Here are the best cheap dab rigs for 2020 that one can buy online. What is a Dab Rig? Let us not get ahead of ourselves already. So, what are dab rigs? Dab rig, or sometimes called Oil rig, is a form of a glass beaker. It is a type of bong or a glass pipe precisely optimized for smoking. It is used for smoking recreational drugs, mostly rosin, shatter, ice, glass, and butane hash oil. A butane torch heats the dabbing concentrate on the dab rig nail. Dabbing is considered safe and avoids combustion of the material.  It provides the most concentrated and highly psychoactive effect with a minute amount of cannabis. Why switch to Dab Rig?…

The Chemistry of Anxiety Chen (2013) defines anxiety to be a state of negative mood that is characterized by fear about the future and symptoms of physical tension. Imbalanced brain chemicals can contribute to mood and anxiety disorders. According to the chemical imbalance theory for panic disorder, chemical messengers known as neurotransmitters are responsible for sending messages throughout the brain, which can lead to anxiety if one or more is not balanced (Colckovic & Nazir, 2019). These neurotransmitters include; Serotonin- controls sleep, appetite, and mood. Norepinephrine- controls movement, energy, and attention. Dopamine- controls flight responses and how a person responds to stress. GABBA- balancing relaxation, excitement, and agitation. How Anxiety Involves Chemistry Chen (2013) suggests that among students, chemistry has a reputation for being a boring, complicated, and highly theoretical science. As a result, many students resort to memorization instead of seeking to understand concepts. This negative attitude causes chemical anxiety in them (fear of chemicals or chemistry as a subject/ course). Students perceive the subject to be too abstract, challenging, and only for the bright students resulting in pre- university-level…

Health benefits of Greenhouse Gases Mitigation Introduction Greenhouse gases have proved to be a nuisance in various parts of the world because of the numerous negative impacts that they cause to living things. Human beings, plants and animals always get affected by the emission of these gases. To get a better understanding of the gases together with their mitigation, it is good to understand that greenhouse gases absorb and, at the same time, give out radiant energy. The gases bring about the greenhouse effect. There are various gases in the atmosphere, including carbon dioxide, ozone, methane and water vapor (Montzka et al. 2011). Human activities have led to an increase of these gases in the thermosphere leading to global heating Leading causes of the abundance of these greenhouse gases are human activities, including mining, farming and industrial emissions. People tend to pollute the environment because it is a cheap way of disposing of goods that have been used and produced. The gas concentrations also increase in the atmosphere because of smog caused by the emissions from vehicles and industries. It…

Revolving fund social enterprise in Japanese urban areas The situation in urban areas across the globe is getting complicated based on the ever-growing population. Rapid urbanization trends, high population growth rates, urban poverty, as well as urban-rural migration, are the primary factors that contribute to this problem. Based on the rate at which these factors are spreading, they seem unstoppable in the foreseeable future. It is quite unfortunate that the high growth rate experienced in urban centers is more compared to new employment opportunities. In this regard, many people in these regions live below the poverty line and are unable to meet their basic human needs. It is a problem that is getting worse every day, and therefore something needs to be done to find a lasting solution to this problem (Kim, Yamaguchi, Kimura, Ko, Ikeda, & Shimoda, 2019). Most challenges in urban centers and big cities are associated with insufficient income. The majority of people in the urban centers lack the revenue required to meet their immediate basic needs for shelter, fuel, foods, essential health care, and to meet…
