This blog post is an illustrated review/outline of the first semester of Biology. Images taken from the web will show the most important topics discussed during this semester. These images will prompt you to ‘retrieve’ answers from knowledge gathered during the semester; and relate that knowledge to the images shown. I will ask you questions regarding the images, which are questions that have been discussed at some point during the semester; also, these questions are aligned with the outlines/reviews uploaded to your Edline Bio pages (AP Biology and 10th grade Biology).
I. Life: an introduction
What is emergence? Why is this concept so important in Biology? Why spirals are good metaphors to understand emergence?
Why classification is important in Biology?
What is a gene?
Why are viruses considered ‘biological entities’ and not organisms? What does this tells us about the characteristics of life?
How is this image an example of homeostasis?
Briefly explain the concept ‘common ancestry’ with this image.
Why the scientific method should be understood as cyclical and not lineal? Image via Ars Technica.
II. Life and Chemistry
What is matter? What is an atom? Why are valence electrons important to understand the nature of compounds?
This image is both: a model and an electron microscope image of a chemical (real) phenomenon. What event is illustrated here? Why is this event so important for life?
This image is an artist’s representation of an ancient greek god called Proteus. He was able to morph into any shape he desired. What molecule of life does this image remind you of?
This is a 3D filled model of an enzyme called Hexokinase. Why are proteins important for life?
This image is a carbon allotrope known as a fullerene. Why carbon is important for life?
III. The Cell
What is the etymology of the word ‘Eukarya’?
Why cells cannot be the size of an elephant?
How is this arrangement of organelles called?
What is an ‘endosymbiotic relationship’?
What is this image? What type of microscope was used to magnify this structure?
IV. Diffusion & Osmosis
Refer to the blog post of October 30, 2013 titled: Diffusion and Osmosis (via Khan Academy)
What type of metabolic pathway is illustrated here?
What is energy? What is entropy? How the definitions of ‘energy’ and ‘entropy’ can be related to the Laws of Thermodynamics?
VI. Cellular Respiration & Photosynthesis
For this topic, refer to the following blog posts:
Glycolysis, or how cells break down carbohydrates
The Citric Acid Cycle (via Khan Academy).
Photosynthesis web kit.
