Oxygen

determined to effectively influence muscle oxygen uptake at the cellular level. Evaluating and measuring the effectiveness of the two types of exercise on oxygen uptake would inform the advantages and disadvantages they have on muscles. Significant amounts of oxygen are consumed by the human muscles when moderate intensity aerobic work is performed. Contradictorily, anaerobic exercise causes the body to break down stored glycogen in muscles for energy. Therefore, oxygen availability, biological…

Effect of temperature Results In this experiment, results from two Procambarus propinquus (crayfish) were collected to observe the difference in oxygen consumption at different acclimated temperatures. These cray fish were collected from Medway Creek in London, and acclimated to their new environment and temperatures. The crayfish were exposed to the cold environment having an average temperature of 7° or warm having an average of 22°. An unpaired, two-tailed t test was performed to determine if…

abundant element in the Earth’s crust other than oxygen is silicon which if by mass is around 25.7g or 23%. However in nature, silicon never exist as a free or pure element but instead it mostly combines with the most abundant element in the Earth’s crust, oxygen, hence producing silica (SiO₂) or silicate minerals. The most prominent charge of Si in the crust is +4 rather than +2 which involve a silicon atom to bond in a tetrahedral manner with 4 other oxygen atoms giving rise to the silica…

Oral/nasal cavity- The nasal cavity is the primary intake for air for the respiratory system, consisting of cartilage, muscle and bone. It allows for inhalation of air into the body and warms the air as it enters filtering the air by removing dust, pollen, and other contaminants, purifying the air before it is passed to the inner body. The secondary exterior opening is the oral cavity, it allows for larger quantities of air inhalation, it also has less distance to travel allowing more air to…

Gas Exchange Gas exchange is the process in which gases enter and leave a body by diffusion across gas exchange surfaces. Gas exchange is important as it transfers oxygen from surroundings of an organism to individual cells in the organism’s body, needed by the cells for respiration to occur. Carbon dioxide is released. This process produces energy which is essential to an organism for survival. Group 1 – Insects The definition of an insect is any of a group of small and often winged animals…

organisms. Homo sapiens need oxygen to survive and reproduce. You are a homo sapiens. You need oxygen to survive. The only way in which there will be oxygen surrounding the face of the Earth, is by plants and other organisms converting carbon dioxide into oxygen during photosynthesis. The Amazon Rainforest is the largest rainforest left on the planet. This rainforest is responsible for producing 20+ percent of the oxygen on Earth (Taylor, 1). That is over 1/5 the total oxygen within the…

This method takes into consideration how the methane is broken down, oxidization, which takes molecular oxygen out of the environment. This method was used previously to examine the population of methylotrophs, however in this case the dissolved oxygen levels were used in order to determine where the methane was being actively broken down. The information gathered, lead researchers to discover that the plumes were in fact moving…

Catalase containing, positive, bacteria consist of aerobic, oxygen respiring, and facultative anaerobic, can grow either with or without oxygen, bacteria. Being catalase positive means the bacteria is exposed to hydrogen peroxide in a concentration high enough to make it toxic to the bacteria cells. Thus, the cell needs to break down the hydrogen peroxide into water and oxygen gas to survive. Catalase positive bacteria can include beneficial bacteria. Two harmful bacteria that are catalase…
