Introduction The question of uniformity of matter has been explored through various perspectives in the philosophical dimension. A naturalist position may be a good option on which an emphasis can be made within the scope of the issue. Joseph Krutch, being a significant representative of naturalists, advocated the necessity to...
Organic farming allows maintaining a balance within the ecosystem while producing crops. It is a practice of managing the farming process by integrating site-specific practices and using ecological approaches, as defined by Sustainable Agriculture Research and Education (n.d.). For instance, an organic farming practice includes recycling resources and integrating and...
The brain is the most vital component of the human body. It directs and organizes actions and responses, helps think and feel, and provides human experiences such as memories and emotions. This research paper consists of three parts that highlight the three-dimensional sagittal view model of the brain, the structure...
In the article Interrogating racism: Toward antiracist anthropology (2005), the author Leith Mullings discusses the issue of racism in anthropological studies. In the introductory part of the research, Mullings explains the historical connection between anthropology, racism, and antiracist movements. She states that anthropology has a contradicting history when it comes...
Burmese pythons were introduced there by an invasive method. They feed on other animal species such as birds, crocodiles, and mammals. This type of snake is common in South Florida in the Everglades National Park (Florida Fish and Wildlife Conservation Commission, n.d.). Currently, it is noticed that this species is...
The grey squirrel is a mammal that is native to the United States and some provinces of Canada. Due to its grey fur, the squirrel frequently occurs in city environments since the color increases the species’ survival rate in urban conditions. As a consequence, these animals and their behavior are...
General Introduction Fossils from the Late Devonian period, supposedly more than 360 million years old, were found in rocks in East Greenland. The fossils of this ancient animal made it clear that it had a generally developed system of fingers and limbs, so the species was quickly classified as a...
Introduction The cause of aggression in dogs has been an ongoing debate, with some factions arguing that it stems from the breed of the dog and is hence inherent. Other groups contend that the hostility is due to environmental conditions. Aggression in dogs is characterized by loud backing, excessive hostility...
Dalton’s Atomic Theory (DAT) was a major contribution to the field of chemistry. DAT is based on five assumptions regarding the nature of the world’s smallest molecules. The first hypothesis of this theory suggests that all matter consists of atoms, invisible particles that cannot be observed due to their minuscule...
General Information Ambulocetus survived as a transitional form of cetaceans between terrestrial and aquatic species, so this creature was characterized by going out into shallow water searching for food. Ambulocetus’ appearance was similar to either dolphins or crocodiles, with anatomical structure indicating that the fossil form belonged to cetaceans. Ambulocetus...
The human body is a complex and multilevel system whose components are combined into a coherent and balanced mechanism. The need for molecular oxygen defines the body as an open system, which needs the resources of the environment to maintain effective activity. More specifically, at the macro level, oxygen is...
Introduction The fundamental differences between the British common law system and Quebec’s civil law system are associated with the national, historical, political, psychological, and other characteristics of countries and peoples. Due to its natural and other features, each of these legal systems develops on its own. This development, along with...
General Description of Homo Floresiensis Homo Floresiensis is a primitive hominine species that has become an object of active scientific debates. H. Floresiensis was discovered in 2003 in Lang Bua (Indonesia) in the Late Pleistocene sediments (Sutikna et al., 2016). For a long time, the scientists have been discussing the...
Introduction The concepts of osmosis, diffusion, and active transport concern the movement of molecules and are some of the foundational terminologies of the biology curriculum. Nevertheless, the terms are frequently confused and misunderstood. According to the research by Reinke, Kynn, and Parkinson (2019), most first-year biology students have a large...
Capillaries are small blood vessels that help connect veins and arteries while also facilitating the exchange of different vital elements between tissues and blood. They represent core connections in the arterial system, which includes the blood vessels that carry blood in the direction away from the heart and toward the...
Introduction This study discusses Polycyclic Aromatic Hydrocarbons, which are also called PAHs, as specific chemicals materials that present huge risk for the environment, animals, and human beings. These materials are formed as a result of process of combustion of different materials. The project also mentions the process of calibration and...
Introduction There are no other cells in the human body that can generate more different cells than stem cells. Research scientists have developed an interest in stem cells’ composition and applicability in the medical field (Wang et al., 2017). Cell division of the stem cells can generally occur in the...
Introduction Whooping cough, also known as pertussis, is a respiratory tract infection caused by the bacterium Bordetella pertussis. In earlier days before the development of a vaccine, it was viewed as an infantile disease that affected children, mainly between the ages of 1 and 9. In this age group, it...
The rib cage may also be called a thoracic cage. It has twenty-four bones known as the ribs. The ribs are curved around the chest. A human rib cage has twelve thoracics. The top seven pairs attach themselves to the sternum by cartilage; they are the true ribs (Starr, Beverly...
Purpose The purpose of this lab experiment is to equip learners with essential laboratory techniques and skills employed to avoid contamination of microbial cultures by maintaining purity. This experiment will allow us to utilize an aseptic technique to inoculate a pure culture of Lyompholized Escherichia coli to broth, slants, and...
Human beings have been trying to decipher their origin and roots for centuries onwards. They easily observed that living things inherit traits from their parents, and used this finding for the cultivation of certain features in animals and plants. But the means of such heredity represented a mystery to people...
Broadly, archaeology scientifically studies prehistoric and historical human activities by recovering and analyzing material culture. As such, archaeologists excavate and describe past human-made objects ranging from simple tools such as stone daggers to complex structures as temples and cathedrals. On the other hand, classical archaeology has traditionally focused its attention...
Genetic engineering is the manipulation of the genes of an organism by completely altering the structure of the organism so as to come up with different characteristics of the same organism. Genetic engineering has been successfully applied in different fields with a lot of success especially in the disciplines of...
For muscles to contract, the muscle fiber creates tension within itself. This tension is brought up by the action of myosin and actin cross-bridging sequence. Contraction in muscles generally means the generation of tension by the muscles with the help of neurons (Starr, Beverly 108). “The sliding-filament theory of muscle...
