Human movement is carried out by the musculoskeletal system. There are essential structures like bones, muscles, and ligaments in the human body that work to produce a human movement. A lever is a firm bar that revolves around a fixed point or fulcrum. The lever has three parts, fulcrum (axis), force (effort), and resistance (load). The human body parts function similar to the parts of the lever. The axis of the lever represents the joints in the human body. The lever arm represents the bones. The force of the lever is similar to the region where the muscle is attached. The resistance of the lever is the force exerted to overcome the weight. Effort arm is the portion of the lever that starts from the fulcrum to the point of effort, whereas resistance arm starts from the fulcrum to the point of resistance.

Introduction:

Human movement is carried out by the musculoskeletal system. There are essential structures like bones, muscles, and ligaments in the human body that work to produce a human movement.

A lever is a firm bar that revolves around a fixed point or fulcrum. The lever has three parts, fulcrum (axis), force (effort), and resistance (load).

The human body parts function similar to the parts of the lever. The axis of the lever represents the joints in the human body. The lever arm represents the bones. The force of the lever is similar to the region where the muscle is attached. The resistance of the lever is the force exerted to overcome the weight. Effort arm is the portion of the lever that starts from the fulcrum to the point of effort, whereas resistance arm starts from the fulcrum to the point of resistance.

Students have asked these similar questions

a) What differences would you expect to see between the -DNA/+Amp and +DNA/+Amp plates? b) Predict the growth you would expect to see on each of the following plates: – DNA ___________________________________________________________ – DNA/+Amp ______________________________________________________ +DNA/+Amp ______________________________________________________ +DNA/+Amp/+IPTG _________________________________________________

1)Which plate did you see purple/pink/blue bacterial cells? Why did you see this growth? Explain your answer in terms of transformation and plasmids? 2) Calculating Transformation Efficiency For the +DNA/+Amp/+IPTG plate, record the following: Number of transformants (colonies): _________________ Nanograms of plasmid DNA added: 50 ng Final recovery volume: 0.50 mL Volume plated: 0.25 mL Transformation efficiency equation: Transformation efficiency = Number of transformants / µg of DNA x Final volume at recovery (mL)/ volume plated (mL) 3) Using the equation above, calculate the transformation efficiency. 4) Describe the success of the transformation efficiency of this demo based on the calculation you did above?

1) Look at the ideal results. Were your predictions accurate, and how did they compare with your results? 2) You used aseptic technique during this lab. Why is it important to work in a sterile manner when working with bacteria in the lab? 3) Why are the cells incubated at 42°C?
