model validation and testable hypothesis regarding specific conformational changes that control bond profiles, thereby suggesting structural mechanisms for the inner workings of the TCR mechanosensing machinery and plausible explanations of why and how force may amplify TCR signaling and antigen discrimination....
Two strips, one of iron and one of zinc, are riveted together side by side to form a straight bar that curves when heated. Why is the iron on the inside of the curve? Define what tension is and explain how t...
Explain how joint structure affects strength (resistance to dislocation) and flexibility (type and range of motion). a. Identify three impacts of the HIV/AIDS crisis on ethical decision making. b. What are these impacts and how do they work?
Explain how joint structure affects strength (resistance to dislocation) and flexibility (type and range of motion). What are two things a muscle spindle senses? How do you explain abduction in the muscle control formula? Explain why the testes are suspended out...
(b) Give examples of each type. Why do potassium levels have such a strong effect on muscle function? Explain. Describe the role of ATP in muscle contraction. As you fatigue, the force exerted by your muscles decreases. What physiological processes explain the decline in strength? Explain ...
The size of this voltage is directly proportional to the size of the electric current and the strength of the magnetic field. Which way do they go? How do you figure out which way the electrons will move? You can work out the direction of the Lorentz force with Fleming's left-hand ...
[1] In theory, the only thing that affects how fast a pendulum swings is its length and the strength of gravity. For relatively small swings, the time (T) it takes to make one complete swing (known as the period) is given by this little equation:...
Why do endurance, strength and power athletes need more protein than the RDI? Why does when a person loses their vision, their other senses compensate? Define the expiratory reserve volume (ERV). Explain how low oxygen in the blood affects the bra...
How would the type of gel influence this movement? Explain. Gel Electrophoresis: Gel electrophoresis is a technique used in molecular biology to separate DNA fragments and other molecules by size. An electrical current is applied to a gel, causing the fragments to move through it at different ra...
Finally, if you need industrial-strength air cleaning, there's a tougher standard called ULPA (Ultra-Low Penetration Air) that can catch 99.99 percent of particles 0.12 microns and above. However, the relationship between ULPA and HEPA can be confusing: it's worth noting that "a simple HEPA...
