Hint: check on volt/cm).The virus SARS-CoV-2 which causes covid-19 has quite flexible nail protein. Make a simplified biomechanical equilibrium model based on the black and white card (electron microscopy). Assume that C is a pin joint. Joint B is described as a torsion spring with force pair moment M = κα, where α is the angle in radians. Suppose further that force from above can be modeled as gravity in A, and that the medium acts as a vertical roller support at R. Dimensions: LBC = 100 nm, LAB = 2LBC.

- Briefly - state the experimental observation that is known as Chargaff's Rules (Briefly means TWO sentences maximum)Blood lactate is a biochemical by-product that is produced during high-intensity exercise due to insufficient oxygen intake. Commercially available drinks advertised as oxygen sup- plements claim to increase exercise performance and decrease the postexercise recovery period by decreasing the accumulation and accelerating the removal of blood lactate. To test this claim, researchers conducted a controlled experiment to compare the concen- tration of blood lactate during exercise and during recovery between two participant groups, one that ingested oxygen-supplemented water and another that ingested regular water.
