The discovery of patterns of inheritance enabled many fields of biology to be unified. One process that is better understood by genetics is meiosis. Describe the process of meiosis and describe Mendel's two experiments (monohybrid and dihybrid) and Morgan's experiment on recombination. Describe how these threOKe experiments illustrate the process of meiosis.

In a Compton scattering experiment, an x-ray photon scatters through an angle of 19.0° from a free electron that is initially at rest. The electron recoils with a speed of 1,240 km/s.

(a) Calculate the wavelength of the incident photon.
nm

(b) Calculate the angle through which the electron scatters.
