The Current State of the Galapagos Islands

The Galapagos Islands are well known for Darwin’s observation of the various types of finches that live there and his subsequent theory of evolution. Less known though is the current predicament that has engulfed the islands. It was by chance that Darwin was able to observe these islands off the coast of South America firsthand...

Example of the Scientific Method in Action

Plainly stated the scientific method involves taking an observation, asking a question about that observation, brainstorming possible answers culminating in the most probable answer, quantitatively testing that answer, and finally coming to a conclusion as to whether the most probable answer is the best answer given the test results. At that point, if the most... Continue Reading →

Cellular Respiration: Glycolysis

Slide 2 Notes Glycolysis is only one segment of cellular respiration (Pruitt, Underwood, 2005). Glycolysis is the most primitive of the types of cellular respiration. Glycolysis does not required oxygen so it is called anaerobic. There are four major steps in glycolysis. The process begins with a molecule of glucose. The glucose molecule is exposed...

Patterns of Evolution

Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms? Why or why not? Yes, humans are subject to the same pressures of natural selection as other organisms. However, I would say that I think humans are subject to some pressures of... Continue Reading →

The Difference Between Mitosis and Meiosis

Why are the processes of mitosis and meiosis both important to a living organism? Mitosis is the process by which existing cells asexually reproduce to create sister cells. Without this process, there would be no way for our bodies to replace damaged, infected, or dead cells. Since cell theory states that all cells are created... Continue Reading →

Mendel on Patterns of Inheritance

How did Mendel’s approach to answering scientific questions differ from that of his contemporaries? Well, there were many differences between Mendel and his contemporaries. For instance, he applied mathematics to plant breeding, which no one else had done. By doing this he was able to accurately track gene inheritance, even recessive gene inheritance, through many...

Ecology and Population Growth

What is the current estimate of the worldwide human population at this moment? Describe how this number is changing moment-to-moment, day-to-day, and from one year to the next. The current worldwide human population at this moment is 6,555,336,000. This is a huge number. I knew that the current population was around 5 or 6 billion,... Continue Reading →

Theories of Biology

Evolution by Natural Selection Evolution is widely viewed as the foundational theory of biology. There are two parts to the theory of evolution. The first part establishes that species can evolve over time. The second part states that this evolving is accomplished through natural selection. Inheritance Inheritance is a theory which predicts that traits and... Continue Reading →

Characteristics of a Living Organism

Ten characteristics distinguish an object or thing from an actual living organism. All 10 characteristics must be present simultaneously in order for something to be considered living. The following table lists four of the 10 characteristics that make up a living organism. Fill in the remaining six characteristics: Characteristics of a Living Organism 1. Composed...

The Laws of Thermodynamics

You are a patent agent, and an inventor comes to you claiming that he has invented a self-powered engine that requires no fuel to run. Will you agree to patent this invention? Why or why not? I would not agree to patent such a device. I have studied perpetual motion for some time. I used... Continue Reading →

Personal Local Ecosystem

Describe the ecosystem in the area in which you live in terms of plant life, animal life, and geology. What populations and communities are present? Humans are indeed the great eroders. I live in a large city, Fort Worth, Texas. The entire area has been remade into a suburban area. As a consequence the predominate... Continue Reading →

How Biotechnology Could Benefit Society

For your assigned biotechnology example, provide at least two ways the use of this biotechnology could benefit society, and two ways this biotechnology could be harmful. One of the best examples of historic biotechnology could be Mendel’s peas. At that time many pea types had been specially selected and breed to bring about the best... Continue Reading →

The Genetic Basis of Hemophilia

Consider the other European families affected by the hemophilia gene. If you were a member of one of these families, what would be some implications? I guess that really depends on whether you plan on having children with this person or not. From what I have read royalty usually favors many children in order to... Continue Reading →

The Evolution of DNA in the Body

What are some of the benefits of squeezing so much data into virtually every cell in the body? Why did we not evolve with one central repository of DNA rather than having it replicated throughout the body? One of the benefits has to be that our genetic information cannot be lost simply by removing one... Continue Reading →
