what the sun is composed of, ultraviolet rays, and ozone depletion needs to be understood. Our Sun is the central part of our solar system; if the sun didn't exist several things wouldn't occur: the process of photosynthesis would not take place, oxygen cannot be created, thus, life cannot be present. The Sun is mostly composed of “ hydrogen and helium”(Helmenstine). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion making the Sun a…
and from the human body. Water is also found everywhere on Earth. It can exist as a liquid, solid or gas. Many organisms use water in order to flush toxins anything into and out of a cell. Without water there would be no vegetation on land and no oxygen. Basically without water life would be impossible. Water is vital for all living things on Earth and is the vital force behind the Earth’s climate. The Water Cycle, which is the "first" step in the water cycle this happens when energy…
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…
Most proteins are enzymes, which have an essential role in biological catalysis by increasing the rate of a reaction. The experiment conducted included an enzyme assay with the enzyme catalase and the substrate hydrogen peroxide. To complete the assay, the catalase enzyme was added to the hydrogen peroxide buffered solution. Every thirty seconds, portions from the tube was removed and placed into the labeled tubes. Based on the degree in color of each sample, a different absorption value would…
Acid rain results in many ecological effects, with the most severe of these affects being its impact on lakes, streams, and aquatic environments in general. It negatively affects marine life, because acid rain makes waters acidic, causing the absorption of Aluminum; which is a combination that threatens some aquatic animals. As the acidity of water increases, the number of fish and marine animals in general decline. Although, there are some species that are able to survive in acidic water,…
Yeast is used nearly everyday all over the world in such quotidian items as bread and alcoholic beverages. To grow yeast, the sun is not necessary because yeast does not photosynthesize, Instead of yeast obtaining energy to grow from the sun, it processes sugars and disaccharides to make energy, with carbon dioxide as a byproduct. While sunlight does not directly aid yeast’s growth, it does affect yeast’s respiratory oscillation, which is an activity that impacts metabolism and energy production…
Mitochondria are the powerhouses of the cell that act like a digestive system which consumes nutrients, breaks them down, and manufactures energy for the cell. This chemical processes of the cell is known as cellular respiration (1). Most of cellular respiration happens in the mitochondria. Mitochondria typically float around free throughout the cell. Some cells have hundreds of mitochondria, like muscle cells, while others have little to none, like nNeurons (1). The quantity of mitochondria a…
Ocean acidification is detrimental to calcium carbonate life. As CO2 is absorbed into the ocean, it has a chemical reaction with water and forms carbonic acid, lowering the pH. This acid reacts with the calcium carbonate that many shellfish need to build their homes and protection, forming a different type of molecule, and depleting the ocean’s calcium carbonate resources. While it was obvious in our lab that our four mollusks, wrinkled drill, cowrie, small oyster, and large oyster, were to be…
respiration, in addition to the production of carbon dioxide in organisms from two different kingdoms.A big difference existed betweem the production of carbon dioxide among each creature and that was clearly noticeable in our data.Animals rely heavily on oxygen gas which is the product outcome of Photosynthesis. In the other hand, plants need carbon dioxide and on this experiment the production of carbon dioxide lacked, mainly because Elodea was not allowed to photosynthesize due to the foil…
adult does. Instead, the fetus draws its oxygen from the mother’s blood where the oxygen content is low. The hemoglobin in adults consist of two alpha and two beta subunits. Fetal hemoglobin consists of two alpha and two gamma subunits. This allows hemoglobin to bind oxygen with higher affinity compared to adult hemoglobin, allowing the extraction of oxygen from maternal circulation. It Is important in fetal development because fetal hemoglobin is the main oxygen transport protein during the…
