under more physical exercise. When humans breathe the body converts oxygen in the air into energy, which is then transported to the muscles by red blood cells, which allows us to exercise for a longer period of time. The respiratory system recovers after exercise by making us continue to breathe heavily. We do this because when the human body is put under physical exercise the body has oxygen debt which means that there is an oxygen shortage in the body and to get…

Most enzymes are catalytic proteins made up of amino acids and are a key part of the breakdown and synthesis of virtually every biological catalysis reaction mechanism. The primary function of a catalytic enzyme is to increase the rate of reaction by helping the enzyme overcome the activation energy barrier without the reaction consuming or changing the enzyme. In enzymatic reactions, the substrate binds to the highly specific enzyme active site (the substrate-binding domain) and forms an…

Lake Erie needs our help desperately! The danger is that Erie is so polluted with raw sewage and poisonous chemicals, blue and green algae is a huge problem right now, because of the heat, it keeps on reproducing this fatal mush. 1960 was the most polluted it's ever been, so much pollution they protested to make the lake better. The lake was full of Nitrogen and Phosphate. Dead fish littered the shoreline, the lake was remembered as “dead lake’’. The United States signed a treaty with Canada…

Precambrian time covers the tremendous greater part of the Earth's history, beginning with the planet's creation around 4.5 billion years prior and finishing with the development of complex, multi celled life-shapes very nearly four billion years after the fact. The Precambrian is the most punctual of the geologic ages, which are set apart by various layers of sedimentary rock. Set down over a huge number of years, these stone layers contain a lasting record of the Earth's past, including the…

fact that to create water, it takes oxygen and hydrogen burning together. However, these raw elements are not laying around for Watney to use, therefore he comes up with a way to acquire the two gasses. First, Watney reasoned that that the MAV fuel plant was still left behind despite the launch of the spacecraft when his team left. This meant that there was an adequate amount of carbon dioxide remaining to transfer through the oxygenator to make enough oxygen for his goal of 250 liters of water.…

During respiration, gas exchanges take place as part of the reaction; in the case of animals, gas exchange takes place in the lungs, where CO2 and water vapors are exhaled and oxygen is taken into the bloodstream. Foxes contribute to the water cycle as they respire, breathing out water vapors that rise to the atmosphere. Foxes also contribute to the water cycle through perspiration. They perspire to prevent overheating; during…

Sowbug Experiment Introduction A sowbug is an isopod that belongs to the Classic Crustacea family. They live in damp, wet, dark environments and are commonly nocturnal. They are mostly found under rocks, rotting tree bark, or logs in moist, dark areas outside. Through the observational study I observed that the sowbugs most often moved towards the edges and buried themselves, they moved quickly, and they mostly stayed and/or ended up on the damp-dark soil rather than the dry-light sand. Based…

Chemical Contamination Hajra Takala Benedictine University Professor, David Milen, Ph.D.,MPH, MS, BA, AAS Chemical contamination refers to the presence of unwanted substances that make the food, air, or water unfit to use. There are two forms of chemical contaminants organic and inorganic. We have chemical contaminant in the substance that we are using every day. There is property or characteristic for some contaminants which is volatile, this lead to having like these contaminates in our…

Introduction Homeostasis is the state of a stable internal cell environment. If the cell is not in a state of homeostasis, then the cell will not be able to live and function properly. The plasma membrane is selectively permeable and controls what molecules enter and exit the cell. The plasma membrane keeps the environment inside the cell relatively stable which is the state of homeostasis. The goal of this investigation is to see if the size of the cell is affected when the cells are put in…
