Thermal Expansion and Contraction Most of the matters‚ without some exceptions‚ expand with the increasing temperature. When you give heat to matters; speed of its particles increase and distance between them also increase which results in the increase of the volumes of matters. All expansions occurs in volume of the substance however‚ sometimes some of the dimensions of them expand more with respect to others. In this case we neglect the less expanded ones and assume expansion like linear expansion

Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres. Type 1 fies take approximately 110 ms to reach peak tension when

Summary In this lab‚ students took basic vitals and body scored dairy cows at the University of Maine’s‚ Witter Farm. These basic vitals included respiratory rate and ruminal contractions in addition to observing body condition. Upon arrival to the farm‚ students were led to a classroom where a presentation was given by the professor which covered basic cattle handling skills and safety techniques as demonstrated in videos from the University of Wisconsin. After the presentation‚ students were

What is athletic training? Athletic training is the concern of the well being of the athlete and generally assumes the responsibility for overseeing the total health care for the athlete. This basically states that an athletic trainer’s job is to be there for the athlete whether he/she is injured or not‚ and to practice the prevention of injury. By learning the proper techniques and steps to stretching‚ an athletic trainer can pass that information onto the athlete to help prevent common problems

Week 1 Chapter 1 1. What is the basic difference between anatomy and physiology? (p. 2) ANSWER: Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the science of structure and the relationships among structures. Physiology (fiz′-ē-OL-ō-jē; physio- = nature‚ -logy = study of) is the science of body functions‚ that is‚ how the body parts work. 2. Define each of the following terms: atom‚ molecule‚ cell‚ tissue‚ organ‚ system‚ and organism. (p. 6) ANSWER: AtomUnit of matter that makes

Bones in our body are living tissue. They have their own blood vessels and are made of living cells‚ which help them to grow and to repair themselves. Every single person has a skeleton made up of many bones. These bones give your body structure‚ let you move in many ways‚ protect your internal organs‚ and more. As well‚ proteins‚ minerals and vitamins make up the bone. Bones have several parts‚ but are manily made out of calcium deposits. It takes around 20 years for our bones to completely
