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.

You have 1000 volunteers to find out if taking Zinc supplements at the first sign of a cold really shortens the duration and lessens the symptoms.
Describe how you would design an observational study to determine this.
Now describe how you would design an experiment to determine this.

i need a good introduction for a lab report about (isolation of caffeine from No-Doz tablets) . i am really not good at writing introduction and councluion.
for introduction i only wrote ( The purpose of this experiment was to extract the caffeine from a No-Doz tablets by recrystallizing it.) please help!!

What is Plank’s constant and the significance of this constant? A ray having an energy of 12 eV is required to create an electrical current in a circuit when the ray is shone on a piece of metal in the circuit. Determine the frequency of this ray. What is this called and what major revelation resulted from this type of experiment

When 6.597 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 21.74 grams of CO2 and 5.935 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 40.06 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.

how can gel electrophoresis be used to determine whether a ligation experiment was successful? Be specific with what you would expect to see in the various lanes of the gel if a ladder, comtrol ( digested plasmid + insert without ligase) and sample ( digested plasmid + insert with ligase) were run.
