hii Anubhav , 

As you not mentioned your category here . we can not say that admission will happen or not .   But according to your marks and  rank there is the Chance of admission is very few. You can wait for 2nd or 3rd round counciling . But my suggestion apply some other college like DU and state university for B.Sc. biology.

For more information related to admission - https://www.google.com/url?sa=t&source=web&rct=j&url=http://bhuonline.in/&ved=2ahUKEwi_-MqstfriAhXKQo8KHTJgDyIQFjAAegQIBxAD&usg=AOvVaw18wXL8CGIXxONTCOcwkNev

Hope it helps !!
