Oxygen

collect plankton and benthos specimen that were put in a specimen jar. A water sample was collected to measure the dissolved oxygen in the water, phosphate in the water, nitrate in the water and the hardness of the water. Three hach kits were used to measure three different properties of the water of the stream. The Dissolved Oxygen hatch kit was used to measure the dissolved oxygen in the water. The Nitrate hach kit was used to measure the Nitrate (NO_3) in milligrams per liter. The Phosphate…

a union was eons ago when the level of oxygen in the atmosphere was starting to increase. At the time, eukaryotic cells could not metabolize oxygen until the bacteria invaded them. Due to the living conditions and the eukaryote’s “ cellular machinery”, they formed a symbiotic union (Krogh, 2014, p.349). Over time, the bacterium becomes an essential part of the eukaryotic cell. The bacterium made the transition of becoming an organelle that metabolizes oxygen known as the mitochondrion. It is…

chloroplasts and together with carbon dioxide and water, it is turned into glucose and oxygen. The glucose eventually gets used as energy for the plant to live and the oxygen is a waste product that is released. The oxygen is used by humans during cellular respiration. Photosynthesis began over 2 billion years ago when an organism first learned to make its own food and excrete oxygen. This caused too much oxygen in the atmosphere and many organisms could not tolerate this. However, this…

biological molecules contain carbon, hydrogen, and oxygen. A carbohydrate (C,H,O) is a biological molecule consisting of hydrogen , carbon, and oxygen atoms exclusively. They are the building blocks for polysaccharides, larger more complex carbohydrates. An example of a carbohydrate is glucose (the energy source for plants). Carbohydrates are the source of short term energy in organisms. Proteins (C,H,O,N) are made of carbon, hydrogen, oxygen, and nitrogen on a base level. Proteins are also…

body's entire homeostasis, or steady state. The cardiovascular systems distributes oxygen rich blood from the lungs to all of the body's organs and tissues by its heart pump and many arteries and veins. Cells throughout absorb what oxygen and nutrients are needed and then dispose of any carbon dioxide and waste which then flow back to the heart's right chambers and on to the lungs to be exchanged for more oxygen. As you inhale, air passes through the nasal passages to the pharynx to the lung…

chemical reactions happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even diseases. In fact, the human body is composed of 65% Oxygen, 18% Carbon, 10% Hydrogen, 3% Nitrogen, 1.5% Calcium, and in smaller amounts of several other elements. Bones make up the skeleton of the human body. They are composed of a collagen rich mixture of calcium and phosphate, which are both…

Totally different from the water’s cycle, the Carbon cycle was more about chemical elements in the ecosystem-atmosphere. Before diving into the subject, to refresh my memory I went back to read book and article to have a good understanding of this cycle. As asserted by Holli Riebeek, carbon is the backbone of life on Earth and mostly all terrestrial beings are made of carbon. Also, carbon was also the fourth largest element in the universe, forged in the heart of dying stars. An article…

Cellular Respiration takes place on the level of the cell, inside the mitochondria. This is the process of breaking down food in the presence of oxygen to form ATP. ATP stands for Adenosine Triphosphate which is an energy bearing molecule found in all living cells1. Things such as bacteria can perform this with their outer membranes. When a person runs, they use cellular respiration to create energy in the form of ATP which allows their muscles to move. Many other energy-consuming reactions of…

Reflective Journal 3- How Plants Tell Time After reviewing chapters six and seven in the Biology Life on Earth textbook while also considering the video titled How Plants Tell Time, it can be concluded that photosynthesis is the most important process on earth in regards to maintaining life. Photosynthesis is an endergonic reaction, meaning that the products involved in the process have more energy than the reactants (Anderson, 18). Because of this endergonic reaction, plants are able to store…

oven cleaner that contains Sodium Hydroxide. Sodium Hydroxide (NaOH) is highly corrosive due to its elements; the presence of oxygen and an electrolyte (Sodium – Na) cause corrosion, the breakdown of a metal resulting from reactions with chemicals in its environment. The oxygen oxidizes with the metal, and the sodium help speed up the corrosion process. The presence of oxygen and electrolytes (Sodium – Na) in sample number 2 make it more…
