Conditions that must remain constant in this experiment include the temperature of the water baths and the volume of peas and beads in the respirometers. The general gas law states that if temperature and volume remain constant, then the pressure of the gas will change in proportion to the number of molecules of gas present. 2. Water moves into the respirometer pipettes because as oxygen is consumed by the peas, the pressure within the pipettes will decrease and thus the negative pressure will draw the water into the pipette. It is important to correct the readings from the peas because the glass beads are used as a control in which no changes should occur in CO2 and oxygen levels due to their abiotic nature.
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
Use a new glucose strip and record Data: Conclusion: According to my data, pH levels do, in fact, affect the results of Lactex. I say this because in my experiment, pre-enzyme, my solutions were all negative except for the soda. I used the test strips to determine if they were negative or positive solutions. After I put in the enzyme, Lactex, my results changed. Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme.
Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
Surfactant promotes easy expansion (inhale) of the alveoli and prevents the alveoli from collapsing during exhale. It also reduces the effort needed for the lungs to expand and contract during breathing. Gas exchange within the lungs and body tissues is vital for life to exist. Briefly explain the PROCESS OF gas exchange that occurs in the lung
Xylem tissue is non-living tissue. * Phloem carries glucose to tissues where it is stored or used in respiration * * * * * * * * * * Movement of Substances in Xylem and Phloem * Current theory explaining upward water movement in xylem involves passive process of cohesion, transpiration pull, tension and adhesion * The source-to-sink model explains active transport or translocation of sugar in phloem * Regulating Water and waste products * Water regulation is essential because: * The water in cells containing substances needed for chemical reactions. Too much or too little water changes the concentration of these substances * Too much or too little water will change the rate at which substances move in and out of cells * Metabolic processes produce waste. These wastes are toxic to cells and must be removed * Wastes include carbon dioxide (Produced during cellular respiration) and ammonia) produced from the breakdown of excess protein). Ammonia is very toxic and need to be removed quickly.
“Fibers that cannot be digested by bacteria in the large intestines are called insoluble fibers because they do not dissolve in water.” (Grosvenor & Smolin, 2006) High fiber diets can produce many benefits, including higher nutrient absorption levels, and better waste output. Diets that tend to lack in fiber or are high in insoluble fiber tend to cause gastrointestinal irritation and constipation. People that experience these symptoms should consider reviewing their fiber sources, and water consumption
You can put on sunscreen or lotion that has a broad spectrum and at least higher than SPF 30. Seek a shade when the sun shining really hot. Since the sun plays a major role in the premature aging of the skin, prevent the sun from damaging your skin cells. You can also ask your in-home caregiver to include these in your elderly loved ones’ health care plan. Protecting your skin from premature aging can actually boost one’s self-esteem from its apparent results.
SALT I believe that setting up a limit for salt intake could be benefial to ones health depending on the individuals daily salt consumption. The current recommended amount of sodium is set at 2,235mg per day which is about a teaspoon. Some of the benefits to reducing the amount is to prevent side effects such as elevated blood pressure, kidney damage, hypertension and water retention, which can also lead to unhealthy weight gain. Salt in the human body acts as an electrolyte, along with other electrolytes they all balance eachother out with water. If one enters the body in excess then the brain automatically lets the body know that it needs more water to balance out the effect leading up to water retention.
Person-to-person transmission is possible because the cysts are infectious when passed in the stool and for a period after. Cysts not only hardy but also can survive in cold water for several months. Giardia survives for long periods outside the body because it has a protective shell around it. This also makes Giardia tolerant to chlorine disinfection. How Giardia is Transmitted Giardiasis is commonly transmitted through contaminated water.
