Activity FOUR There is a direct relationship between the MWCO and the filtration rate; the higher the MWCO‚ the higher the filtration rate. Powdered charcoal is the solute that did not appear in the filtrate when using any MWCO membranes. As pressure increases‚ the filtration rate also increases‚ as long as the MWCO does not decrease. Since we have no control over the MWCO of a living membrane‚ we can increase the rate of filtration by increasing the pressure. The molecular weight

The term biology is derived from the Greek word βίος‚ bios‚ "life" and the suffix -λογία‚ -logia‚ "study of."[4] The Latin form of the term first appeared in 1736 when Linnaeus (Carl von Linné) used biologi in his Bibliotheca botanica. It was used again in 1766 in a work entitled Philosophiae naturalis sive physicae: tomus III‚ continens geologian‚ biologian‚ phytologian generalis‚ by Michael Christoph Hanov‚ a disciple of Christian Wolff. The first German use‚ Biologie‚ was used in a 1771 translation

Did the pH level of the blood change at all during normal breathing? If so‚ how? No‚ it stayed at 7.4 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No‚ it stayed at 40mm Hg Activity 2a: Hyperventilation – Run

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

Memory and Biology There are many events in a person’s life that leave an impression or may “change” a person’s perspective or path. From birth to death the mind is recording lessons and adding to the infinite storage space known as memory. Classical conditioning Lives are filled with many lessons; some of these are learned through classical conditioning‚ operant conditioning‚ and behavioral observation. A simple example of classical conditioning would
