Both could be correct. It would help if you could share the context of what you are talking about. Resembles is probably what you want to use if you don't want to imply "looking" as in physically looking like. Hope that helps.

In the first example, you could actually use either preposition: 1) Nowadays, mobile phones are important to us. Nowadays, mobile phones are important for us. They both are correct and they mean almost the same thing. "to us" will focus on that we personally value mobile phones. "for us" may mean that we recognize the importance of mobile phones in our lives (even if we personally don't value them). Hopefully that helps and I didn't confuse you more!

The most important thing in my life is my family and my religion.

There are a lot of different pills that help with pain. Pain killers are usually the pills that are extra strong in decreasing the pain. These pills are also called narcotics. Hope this helps!

They have very similar meanings. The first one "I'm going to take a bus to visit my friend" makes it sound like you are in the process/action of going right now. "I'll take a bus to visit my friend" tells someone what you plan on doing, but you are not necessarily doing it right now. The first sentence could also be said without doing it right now, but if you were leaving to take a bus right now, you probably wouldn't use the second sentence. Hope that helps!

I would write it as: "They sometimes see women as less effective managers." You could only write this sentence if you already knew who the subject was (who "they" are). Hope this helps!

If you want the gender to be kept a secret then you would say "they." However, when writing English correctly, you would never write "they," you would write "he or she." The word "they" is not singular, which is why it is not correct to use it when referring to one person....but people get lazy when speaking English and use it like that. Hope that helps!
