Usages of Genetic Engineering

There are uses of genetic engineering that can benefit the society. Once again, I reiterate the definition of genetic engineering, which is the direct modification of the characteristics of an organism by manipulating its genetic material by using biotechnology.

Reasons for Genetic Engineering

Genetic engineering is the direct modification of the characteristics of an organism by manipulating its genetic material by using biotechnology. Obviously there are pros and cons for genetic engineering, but for this tutorial, I will state the pros.


Mitosis is the cell division that creates two identical daughter cells to the parent(clones).


In terms of the difficulty of between cell biology and ecology on the Living Environment Regents, generally, ecology questions are easier. There is energy , transferred, and stored, and it is important to know this to understand about how the biotic factors interact. There are energy pyramids, food chains, and even more complex, food webs.

Cell Biology – Practice Questions

These questions are meant for beginner students in undergraduate level cell biology. These are review questions based on material in the first four chapters in “Essential Cell Biology” – See link below.

Biodegradable Veggie Pots: The Art & Sustainability of Making Seed Starting Pots

Vegetable gardening is not just about growing and eating vegetables. Students will learn how their creation of biodegradable pots provides a positive impact in a vegetable garden environment. 1. Learn about biodegradability and the degradation processes. 2. Understand the positive environmental impacts biodegradable objects. 3. Be empowered to grow and secure their own garden vegetables…

Cellular Respiration (Some Background Knowledge Required)

Cellular Respiration is the process by which O2 (oxygen) and C6H12O6 (glucose) is converted into CO2 (carbon dioxide), H2O (water), and ATP–the energy currency of the cell. This process is divided into three stages: 1). Glycolysis 2). Citric Acid Cycle 3). Electron Transport Chain. During Glycolysis, which occurs in the cytoplasm, glucose is split into…

Bipedial development

Bipedal animals are distinctly classified due to the anatomy of the pelvis and foot. This feature is found within the primate order and includes Homo sapiens and other extinct relatives including Homoerectus. The pelvis of a bipedal is shorter in stature and more cup or bowl-shaped compared to other primates. These unique characteristics allow for…

Omnivores, Herbivores and Carnivores

Teeth can tell us a lot about the characteristics of an organism. Certain animals have teeth that are meant to pierce and rip apart flesh. Other animals have a large number of teeth that grind plant matter. Some animals will fall in between these two possibilities which allows them to perform both functions. Omnivores are…


The concentration of a solution is usually expressed as 1M, or 1 mole/L, where one mole is is the formula weight (grams) of a molecule dissolved in one liter of water at standard temperature and pressure. The capital M can be expressed as mM (millimoles), uM (micromoles), nM (nanomoles) and smaller. Concentration is sometimes expressed…
