The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
The first options answer is phloem while the second answer is roots
I think its option b, may carry out nitrogen fixation.
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.
The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.
