This methodology enables researchers to determine if a cell or a gene is vital for some developmental biological process since it requires them extracting whatever cell or gene might be in question, and then seeing if the process is still able to ta Continue Reading...
Cellular Respiration and Function Every living organism needs energy to survive since all cells require energy in order to perform the necessary biochemical reactions that sustain homeostasis within an organism. Cellular respiration and photosynthes Continue Reading...
Wile human beings have always exploited one another, and even looked down upon the so called "other," never before was it possible to claim as a matter of objective scientific fact, that other peoples were simply not "human" and thus could be treate Continue Reading...

On average, male skeletons are larger than female skeletons, but just as some women are larger than some males, this distinction does not hold firm in all instances. Female pelvic regions tend to be wider than male pelvic regions, an evolutionary fe Continue Reading...
Growing Organic Vegetables I just walked by the entrance to a nearby apartment in my complex and began a conversation with an older woman tending her plants. This woman, Janice, had been living here for years and had created a tremendous 'jungle' o Continue Reading...
Cell Junctions - Tight Junctions and Adherens Junctions There are a number of specialized junctional complexes in epithelial cells, formed by molecules that are different from CAMs and SAMs. These comprise of tight junctions, gap junctions, adherens Continue Reading...

"She relaxed limply in the seat. "Oh, no. No. I don't want to go. I'm sure I don't." Her face was turned away from him. "It will be enough if we can have wine. It will be plenty." She turned up her coat collar so he could not see that she was crying Continue Reading...
"When we introduce an intention in our pure potentiality, we put this finite organizing power to work for us." Section 6: The Law of Detachment The law of detachment is simple: if you want something in life, you must give up your attachment to it. Continue Reading...
Split-brain Cases as treated by Bundle Theorists Bundle Theory, as seen above, holds that the unit of consciousness can be explained not as a single individual person but rather as a series of states and events within the mental world of each pers Continue Reading...

The following study suggests that whilst macro and micronutrients are conducive to plant growth it is water that has the greatest impact on, and is the most crucial regulator of plant growth and, when regulated, can lead to the highest growth spurt Continue Reading...
stimuli can affect plant growth rates, robustness, flowering, and even fruit production. We also know that nitrogen is an important part of plant development, and contributes significantly to the thickness, leaf count, and stem width in most plants. Continue Reading...
On a biological level, consumption of genetically modified foods means the potential for "pleiotropic and insertional effects," Dona explains on page 165. Pleiotropic refers to the possibility that a gene may have more than one affect on the food. Continue Reading...
