hill and you was at the bottom of the hill. This calculation is done in your mind, and it’s called physics. You just don’t call it that because it’s so natural. Physics the branch of science concerned with the nature and properties of matter and energy. The branch of physics that is most relevant to football is mechanics. Watching a football game could be teaching you something other than who threw the

8. Thermoregulation- The changes made in order to keep the temperature of someone or something as close to the desired temperature as possible. 9. The Hypothalamus is the portion of the brain that contains sensors that monitor body temperature. 10. a. Two mechanisms the body uses to cool itself is by having the blood vessels in the skin dilate to radiate heat, and having the sweat glands increase sweat production. b. Two mechanisms the body uses to heat itself is making the muscles begin

The experiments are conducted in a closed barn to avoid wind disturbances. The barn has windows on the roof and on the sides so that daylight illuminates the scene. The set up is sketched in Fig.\ref{Set_Up}, with the reference frame used hereinafter. A $15m\times3m$ white tarp sets the background. On the ground, a mesh of ($1\times1m^2$) panels is installed, covering an area of $3\times16m^2$. The blower is a Kuhn Primotor 3570 , positioned $3$ meters from the first row of panels. The camera used

nd Chronic Effects of Exercise on the Body Describe the musculoskeletal, energy systems, cardiovascular and respiratory systems responses to acute exercise (P1 & P2) Explain the response of the musculoskeletal, cardiovascular and respiratory systems responses to acute exercise (M1) There are a number of ways which the musculoskeletal system responds to acute exercise. These include: Musculoskeletal: • Increased blood supply- When we exercise there is an

of the lighting lamp. From the experimental setup, it was showed that the lamps (incandescent lamps) consumes more energy at higher voltages; as the voltage increase, the lamp brightness (intensity) increases. Similarly, as the voltage decreases the lamps brightness appear dim. It should worth saying here that as the brightness increase at a higher voltages, so it consumes more energy and it may lead to a shorter lifespan of the lamp. One of the foremost effect of voltage variations on the incandescent

This assignment is for elementary students who are in 1st grade. This will be an assignment that will be done in the classroom could work individually or by help from classmates. This is a public elementary school in an inner-city setting. The task is an in-class assignment to solve out a puzzle made by the students. The students will have a piece of paper that has a printed image of the classroom photo. The students will cut the pieces of the puzzle through the bold lines then will put it back together

depends on the extraction and clearance of the tracer for that particular tissue. The tracer is extracted by crossing membranes or by diffusion through small gaps between cell junctions in the capillary wall. Membrane transport can be active (requires energy to transport against a concentration gradient), passive (transports with the concentration gradient), or carrier-mediated (transports with concentration gradient with the assistance of a carrier molecule). The interaction of carrier molecules with

What was your selected goal for the semester? My fitness goals for this semester were to be able to maintain my exercise, to be able to do push-ups correctly, and to set a routine in place for my exercise. By maintaining my exercise, I mean to get some endurance. I was able to sprint but not run long distance. In order to achieve my goal, I started trying to gradually make my runs longer and faster. I was able to slowly jog 1.5 miles, but by the end of the semester I had hoped to be able to run

muscle fibre is the Sarcolemma which is the fibres cell membrane and beneath this is the Sarcoplasm, which is the cells cytoplasm, a gelatinous fluid which fills most cells. This contains Glycogen and Fats for energy and also Mitochondria which are the cells powerhouses, inside which the cells energy is produced. Each muscle fibre itself contains cylindrical organelles known as Myofibrils. Each muscle fibre contains hundreds to thousands of Myofibrils. These are bundles of Actin and Myosin proteins which

Ectotherms are cold blooded animals which can control their body temperature by changing their behaviour. Aquatic animals such as fishes are an example of ectotherms along with most amphibians, reptiles and invertebrates. The Waxy Monkey Tree Frog is an ectotherm, this means they are able to regulate their own body temperature by exchanging heat with its surrounding environment. Physical and Behaviour Control – The Phyllomedusa sauvagii has physical and behavioural adaptations to limit water loss
