In California, Pacific Northern rattlesnakes prey on California ground squirrels. Their relationship is a great example of co-evolution. Read the article about their relationship found at https://news.osu.edu/how-is-rattlesnake-venom-like-fine-wine-both-have-regional-varieties/, and then address the following questions: Explain why the relationship between these two species is considered an example of co-evolution. What did you find most interesting or significant about […]

A) Explain how geography, mass extinctions, and adaptive radiation help explain the diversity of living organisms. B) Explain how changes in development can explain the evolution of new life forms. Using the information you presented about geography, mass extinction, adaptive radiation, and embryonic development, from the previous two questions, explain how living organisms evolve.A) Explain what […]

The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered. For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned. To support your work, use your course and text readings and also use outside sources.

Assignment: ReflectionAs you explored a variety of biology-related topics during this course, you may have realized how much the study of biology influences the way you see and understand the world. Taking time to reflect on your learning enables you to deepen your understanding of new ideas and make them more meaningful to you personally. […]

The concept of biological evolution is considered both a scientific theory (which is different than a theory in the colloquial sense) and a scientific fact. Like all theories in science, however, evolution is also subject to refinement and discovery based on new findings. Even today, we are discovering new fossils, or using new technologies to […]

Choice 1: Editing Human Embryos and Adults With respect to gene editing in human embryos, most research is focused on fixing or removing harmful mutations that may cause diseases, but there are some fears of creating designer babies. In addition, we can edit the genes in adults, if we use a targeted approach. Read the […]

Your organs are composed of the four tissue types; epithelial, connective, muscle, and nervous tissues. Organs are wondrous things, each one with a different function vital to the homeostasis of your body. While it is easy for us to view a particular organ as a single item, it is in fact comprised of many different […]

How does the food pyramid work here? Is this a good tool or have you discovered another? How will you measure success? Take manufactured food and read the label. What are the ingredients? Why would this not be a superfood? Obesity and lack of nutrition cause many health problems. List a disease or condition, and […]

The human body is a complex structure. Yet, despite its complexity, it consists of only four tissue types; epithelial, connective, muscle, and nervous tissues. Each has its own unique characteristics and function. During this week’s Discussion, you will focus on the epithelial and muscle tissues. Respond to the two topics below for this unit’s Discussion.
