the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started engaging in their photosynthetic reactions‚ large amounts of oxygen were suddenly released in the atmosphere. This lead to what is known as the Great Oxygenation

Asthma Asthma is a respiratory disease. Asthma has a high reactivity of the bronchial tubes to various stimuli and that reaction blocks air flow by narrowing and obstructing the trachea and lungs. (Woollbert‚ Robert‚ 1996) This causes difficulty breathing‚ and while it’s normally temporary and reversible it can still be life threatening. Normally a person with Asthma has triggers. There are two main sections triggers fall under‚ a viral illness or an allergy. A viral illness is

PH shows that your blood is more acidic and higher PH shows that your blood is more alkaline (base). The PH of your blood should be around 7.35-7.45.if this PH rise or fall‚ it can lead to number of health issues or even death. Respiratory acidosis In the respiratory system‚ lungs remove the excess waste products which is the carbon dioxide when you

conservation of mass. These results do not obey the law of conservation of mass. Possibly she made a mistake recording her numbers. 28. When 31 g of phosphorus reacts with oxygen‚ 71 g of an oxide of phosphorus is the product. What mass of oxygen is needed to produce 13 g of this product? 31g + x = 71g 71g - 31g = 40g oxygen This means that in

In chapter 11‚ we learned about DNA and Genes (11.1DNA: The Molecule of Heredity; 11.2From DNA to Protein; 11.3Genetic changes). DNA (deoxyribonucleic acid)‚ which is in a shape called a double helix‚ developed its name from the simple sugar in DNA (deoxyribose). The phosphate group is composed of one atom of phosphorus surrounded by four oxygen atoms. A nitrogen base is a carbon ring structure that contains one or more atoms of nitrogen. Next to cover is DNA replication in which enzyme breaks

Today‚ I was with respiratory therapy for a second time. This time I was with Amy G.‚ who is a registered respiratory therapist at Deaconess. Amy was working on the 4800 unit today‚ which is the trauma intensive care unit. This intensive care unit is the largest at Deaconess Midtown Hospital. In the 4800 unit‚ there is an office space dedicated to respiratory therapy. In this room‚ there are two computers for charting and storage for equipment such as ventilators. Amy started her one o’clock rounds

The goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus

A molecule is a group of atoms bonded together that represent the smallest unit of a chemical compound that can take part in a chemical reaction. (http://www.dictionary.com) In kitchen chemistry today‚ there are many types of food molecules such as minerals‚ vitamins‚ fiber‚ and water. But there are four molecules that people refer to as food‚ also known as the four basic food molecules‚ which can be used to produce energy which are carbohydrates‚ lipids‚ proteins‚ and alcohol which is not considered

RESPIRATORY PIGMENTS Colored‚ metal-containing proteins that combine reversibly with oxygen‚ found in the body fluids or tissues of multi-cellular invertebrate animals and microorganisms. The role of these pigments is primarily to aid in the transport of molecular oxygen. Thus they are distinguished from respiratory enzymes‚ which are concerned with the metabolic consumption of oxygen. Four distinctly colored groups of respiratory pigments exist among invertebrates: hemoglobins (purple‚ become orange-red
