Naser Alnajem Christian Petersen Oct 9th 2015 Evolution is not a chaotic process. Evolution is associated with the development of new devices, the formation of new species, the progressive development of wildlife. Natural selection is the only factor that is acting in a heterogeneous population, directs the evolutionary process. According to Charles Darwin the premise of natural selection is the struggle for existence. From a modern point of view, through the struggle for existence, the…

Define forensic entomology? Entomology is the highly diverse study of insects and is a subarea of anthropology. The forensic section of entomology deals with application of the the study of how insects relate to criminal matters. In most cases they deal with time of death determinations, location of death, and determining whether the body was moved or not. Bugs eat materials inside of and outside of the body throughout decomposition. A way to use them to determine how long someone has been…

Behavior Due to their rarity and secretive behavior, the LPS is possibly one of the least understood species of large snakes in North America (Rudolph et al. 1997), however, there have been a few studies published that describe the burrowing behavior and movement patterns of the snake. Recently, it has been published that the snake exhibits diurnal activity patterns in its primary habitat of open pine forests on sandy soils with an abundance of herbaceous vegetation (J.B. Pierce et al. 2014).…

On October 31, 2017, at 4:00 pm, I attended the Department of Biology Seminar Series hosted by Dr. Richard Gomer that helped in the Biological Sciences Building East, Room 115. The lecturer was Dr. Carolyn Cannon from the Department of Microbial Pathogenesis and Immunology at the College of Medicine TAMHSC. What intrigued me to go to this lecture was the title, “Wolves in Sheep's Clothing: Killing Bacterial Pathogens with Innocuous Compounds. Surprisingly the title did match the content that Dr.…

Heredity is carried from parents to their children and will affect the health and physical characteristics of that child. Most cells in human body have twenty three pairs of chromosomes, making it a total of 46 but, individual sperm and egg cells have only twenty three unpaired chromosomes. A child receives half of chromosomes from mother’s egg and half from the father’s sperm cell. A male child receives an X chromosome from his mother and a Y chromosome from his father and a female gets an X…

“No problem can be solved from the same level of consciousness that created it.” - Albert Einstein. Over the past few decades, technological advancements have paved the way to new scientific achievements, such as genetic engineering. This involves the manipulation and change of genetics in a living organism by changing its DNA (Morris 137). This new type of engineering has led to the modification of crops, finding cures for genetic diseases, and even the cloning of animals, which could…

Transtheoretical Model and the Precaution Adoption Process Model Both the transtheoretical model and the precaution adoption models are associated with the theory that behavior change is a step by step process that can be utilized change or improve a specific health related behavior. Although, the manner in which the two are initiated differ is several varieties of methods and are therefore, respectively approached and used in different situations. The transtheoretical model and the…

Animal testing, also known as animal experimentation, animal research is the use of non-human animals in experiments that seek to control the variables that affect the behavior or biological system under study. Many say that animals that are being tested are treated humanely but many say that it's horrible and inhumane and no animals should ever be treated on how they are treated in the labs. Medical testing on animals is essential to medical innovations that will save the lives of both humans…

Scientists have claimed that mutation and evolution has saved the lives of many Hawaii crickets. Let's be honest, Evolution is a very controversial subject. Many people believe it, and many people do not believe it. However, let us take a look at how some scientist say the lives of Hawaii crickets were saved because of it. WHAT MUTATION IS Basically, a mutation is a natural process that changed the sequence of DNA. They can effect several aspects in genes. They can alter the products of the…

To begin with , in my consider about animal testing comes down to be a big deal because their are people that are out and will do anything to save these animals from diseases , cancer and more . As in testing what their genetic's can do such as running as fast in 1.2 per second , hopping , swinging and , see how long they breathe under water a'lot of animals is pretty cool of what they can be able to do but when it comes down from a animal getting hurt it depends on us whether we can save or…
