Biology is an interesting, interesting and interesting subject, as it gives the learner a wide knowledge of what is happening in his body from the vital processes and organs that integrate with each other to help the body perform its vital functions. We can say explicitly that biology is the most important subject for studying medicine and pharmacology and delving into animal and plant sciences, microbiology, biochemistry and modern biotechnologies. I will teach this subject, God willing, in both Arabic and English. I hold a bachelor's degree in biochemistry and microbiology from Ain Shams University, one of the best universities in the Arab Republic of Egypt. I wish you success.
