Lab 9: Analysis of Commercial Bleach Introduction Many common products are effective because they contain oxidizing agents. Some products‚ which contain oxidizing agents‚ are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (or NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized from the molecular form (Cl2) to the

The nervous system is always in control of all activities during movement. When a neurotransmitter or message is sent for movement to occur‚ your body releases energy‚ in the form of adenosine triphosphate (A.T.P.). A.T.P causes the contraction or shortening of skeletal muscle. Muscles contract and shorten and as a result of this they are responsible for the movement of the body. In order to have movement the body needs ligaments‚ tendons muscles‚ joints‚ bones and the neurotransmitter or message

Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle Your answer : a. calcium is not released from the sarcoplasmic reticulum. Correct answer: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone

Aquarius(Sports Drink) Background Aquarius is a new isotonic sports drink launched in Asia at the year 2012 by The Coca-Cola Company. Aquarius was introduced in Japan in year 1983 as a grapefruit flavored sports drink as a response to compete for market share with other isotonic sports drinks such as Pocari Sweat‚H2O and 100plus.Aquarius was also the official sports drink for Olympics game in Barcelona in 1992 and 2012.As it’s a new launch product in Asia‚ there’s a need to create awareness to

The heart performed the pump action by a sequence of alternating contraction and relaxation of the heart muscle‚ and the term used for contraction is systole‚ and the term used for relaxation is diastole. I am explaining this because it is very important terms‚ and involve five stages: 1. The vagus nerve stimulate the sinoatrial node or SAN‚ which is the pacemaker of the heart. Is a small area in the upper wall of the Right atrium‚ close to the vena cava; the fibers of the of the SAN contract 70

of this lab is to investigate the reliability of the activity series of metals by testing in solution‚ confirming if the activity series was correct with its predictions. Hypothesis: It is predicted that the metals in solid form will displace metals in solution if located higher over the other within the activity series chart. Materials: 10 test tubes Test tube holder Metals in Solid Form 1. Aluminum 2. Iron 3. Zinc 4. Magnesium 5. Zinc 6. Aluminum 7. Copper 8. Tin 9. Lead 10

The hypothesis for this experiment was that if the baby lemurs activity level was compared to an adults‚ the baby lemur will have a higher activity level. The hypothesis was not supported. The data shows that the adult had a higher activity level. The data shows the adult being 1.8% more active than the baby lemur. The other behaviors of the adult Ring Tailed Lemur was grooming and sleeping/resting. Second‚ throughout the six trials the only behaviors that were performed by the baby lemur was sleeping/resting

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons
