Homework Answers
A. When energy is supplied to an element, it's eelectrons will get excited from lower energy state to higher energy state and while coming back to its original state it emits light and this produces line spectra. The peaks in emission spectra are very sharp so they are called as line spectra.
B. Helium atom consists of 2 electrons and Hydrogen atom consits of only one electron. So since more number of electrons are getting excited to higher levels in case of helium, it will have maximum lines in emission spectra than in hydrogen.

You introduced the pGlo vector into E. coli which carried the
GFP gene under the control of the arabinose
promoter. Based on what you know about the arabinose
promoter, when did you expect GFP to be expressed?
I expected the green fluorescence
protein to be expressed when arabinose was present.
What hypothesis was tested by the experiments you performed
after the pGlo vector was...

need help with this. thanks
Please answer the following questions by replying: 1. Why is it that during alpha emission, the atomic number decreases by two, and the mass number decreases by four? In your answer you should consider what an alpha particle is. 2. In beta emission, the atom loses an electron, yet the atomic number increase by one and the mass number stays the same. How is this possible? It may help if you consider what happens to...
