If your voice gets hurt tell your teacher because if you wait your voice could sound weird or sound completely different from before If your voice gets hurt tell your teacher because if you wait your voice could sound weird or sound completely different from before you hurt it. This can happen if you don’t warm up your vocal chords before a lot of singing. They help

Epithelial tissue protects your body from moisture loss‚ bacteria‚ and internal injury. There are two kinds of epithelial tissues: Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example‚ the outermost layer of your skin and other organs‚ and the internal surface lining of your lymph vessels and digestive tract. Glandular epithelium secretes hormones or other products such as stomach acid‚ sweat‚ saliva‚ and milk. Connective tissue generally

T I V I T Y 3 Effect of Increases in Stimulus Intensity 3. Observe your tracings. How did the increases in voltage affect the peaks in the tracings? They increased with each increase in voltage. How did the increases in voltage affect the amount of active force generated by the muscle? The force increased. What is the voltage beyond which there were no further increases in active force? Maximal voltage: ____8.5____ V Why is there a maximal voltage? What has happened to the muscle at this voltage

Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple

A warm‚ safe‚ and caring environment allows students to “influence the nature of the activities they undertake‚ engage seriously in their study‚ regulate their behavior‚ and know of the explicit criteria and high expectations of what they are to achieve” (Queensland Department of Education‚ 2005).
