How do muscles get oxygen? Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in […]
Is tens AC or DC?
Is tens AC or DC? A standard TENS unit typically delivers a low-frequency (<50 Hz) alternating current to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being […]
Which type of neuron is the fastest?
Which type of neuron is the fastest? Newsletter. 268 Speed (in miles per hour) at which signals travel along an alpha motor neuron in the spinal cord, the fastest such transmission in the human body. Sensory receptors in the skin, which lack the speed-boosting insulating layer called a myelin sheath, are among the slowest, at […]
Can be broken down into two or more components?
Can be broken down into two or more components? Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. mixtures are phisically combined structures that can be seperated into their original components. A chemical substance is composed of one type of atom or […]
Why Bubbles are not formed in water?
Why Bubbles are not formed in water? Atmospheric gases such as nitrogen and oxygen can dissolve in water. The amount of gas dissolved depends on the temperature of the water and the atmospheric pressure at the air/water interface. Hence bubbles along the insides of your water glass. Where do you think the bubbles came from? […]
What happens at an evidence hearing?
What happens at an evidence hearing? The preliminary hearing is like a mini-trial. The prosecution will call witnesses and introduce evidence, and the defense can cross-examine witnesses. If the judge concludes there is probable cause to believe the crime was committed by the defendant, a trial will soon be scheduled. How do you win a […]
Is Moon hotter than Sun?
Is Moon hotter than Sun? Temperatures on the moon are extreme, ranging from boiling hot to freezing cold depending on where the sun is shining. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 […]
Which rock is classified as an evaporite?
Which rock is classified as an evaporite? Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. Which of the following igneous rocks will cool the fastest? Extrusive igneous rocks form above the […]
How is the state of water determined?
How is the state of water determined? The number of bonds between molecules determines whether water will be a solid, liquid, or gas. In the solid state, water molecules have the maximum number of hydrogen bonds (4 per molecule), giving water the rigid characteristic of ice. What are three different states of water? Water can […]
What are the factors that affect soil stability?
What are the factors that affect soil stability? factors influence the size, distribution, and stability of soil aggregates. Among these factors are the method of taking and handling the sample, season of the year, moisture content of the soil at time of sampling, past soil management practices, and method of determining and expressing soil aggregation.
