Reward of Zikr, Remembrance of Allah, Adhan, Recitation of Quran for women not covering head

Can women recite Quran, Do Dhikr, Remember Allah, respond to Adhan without covering head?

Answer 

They may recite Qur’an and remember Allah, may He be glorified and exalted, even if they are bare-headed, if there is no non-mahram man present with them. That does not prevent the angels from coming in.
