Weathering and Erosion in Desert Environments

Weathering is the separating or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salt, plants, creatures, and changes in temperature are the typical weathering agents. Once the rock has been broken, a procedure called erosion transports the bits of rock and minerals away. No rock on Earth is sufficiently

Mount Pinatubo

Mount Pinatubo of the Philippines was the largest volcanic eruption of the 20th century. Its impact had caused major environmental changes, vegetation growth, and liability costs for those involved (including the U.S.). This was a matter of a “sleeping giant” that was combined with the coincidental Yunna typhoon, which assisted in carrying its massive ash

Cell activity during jogging and weight lifting

Our body is in oxidative/aerobic energy system when we are jogging. Inside our cells, ATP is created by breaking down sugar/glucose and is usually generated within 10-120 seconds. Prolonged activities such as marathon runs and jogging, where endurance rather than power is the goal, depend mainly on aerobic respiration. Levels of CP and ATP don’t

Is the volume of an ideal gas really zero if cooled to absolute zero?

When gas is cooled, it contracts, that is, its volume decreases. Absolute zero is largely a theoretical temperature. Scientists have been able to get very close, but due to certain fundamental laws of physics achieving true absolute zero is likely impossible. Now a Question for us to think about is: Is the volume of an

Biochemistry Lab Introduction: Preparation and Characterization of Plasmid DNA

When two pieces of DNA from different sources are joined together, recombinant DNA can be formed. DNA molecules can be cut into pieces by a kind of enzyme called the restriction endonuclease. After cutting, restriction endonuclease cleavage leaves the “sticky” ends that allow two fragments to associate by the base pairing process. The fragments can

The Carnot Cycle

The Carnot cycle explains the reversibility of gases that is broken down into 4 processes. One in which the reversible gas is expanded, the ideal gas absorbs heat from a heat source and expands onto its surroundings. The second process explains that there is insulation, so when the gas expands into the surroundings, the system
