Science is about finding the answers to questions, and philosophy is about working out what the right questions are, which can be surprisingly tricky. The two progress hand in hand. Philosophy isn't just 'bad science'.
No. Science is about empiricism - scientific method, experiments, etc. Philosophy is an overarching field encompassing all pursuit/love of knowledge. It's why another term for science is natural philosophy. It's why people who attain the highest level of education get a doctorate of philosophy ( PhD ).
