Describe the major differences in acute versus passive range of motion (rom) when distinguishing between an articular and nonart
Ierofanga [76]
The question should be about active vs passive range of motion.

In the active range of motion, the test is done by asking the patient to move their body themselves. In this case, the patient should use their muscle to move their body. If there is a restriction in this examination, it could be caused by the muscles or the joints, or the nervous system that used to contract the muscle.
In the passive range of motion, the test is done by the examiner moving the patient body. Since no muscle used, the test shouldn't be influenced much by the muscle. Then, if there is an articular joint issue, the restriction would be found in both passive and active ROM, but the nonarticular joint issue might only cause abnormality in the active ROM.

Answer:

C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation

Explanation:

Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.

Burka [1]

This scientific law is called as Law of conservation of energy.

Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food   and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.

In the first part of the dna isolation, you discarded the supernatant and kept the cells. however, after processing the sample w
pishuonlain [190]
<span>For the first step, you must isolate the cells from the media. The cells contain the DNA so you keep the cells and pellet. The next step would be a cell lysis which causes the cells to open and the DNA to come out. At this point you would keep the supernatant, as the pellet is the cell membrane and other parts of the cell. The chelex is to bind to transition metal ions. This would cause and DNases in the cell to become inactive because the metal ion is their cofactor. The pellet in this case would contain the chelex and the DNA would still be in the supernatant.</span>
