biographical information, fax and maybe even addresses. These are WordPress or theme specific fields which are not visible on frontend profiles. BP doesn’t use them if you use the xtended profile component.
Anyway…

Try this snippet, and use it to your need from within your child-theme functions.php

function remove_user_fields(){

// Print jQuery that removes unneeded elements
  ?>

  <script type="text/javascript">
    jQuery(document).ready( function($) {
    // the magic goes here...
      var ids = ['#description', '#comment_shortcuts', '#color-picker']; // Check in page source for other ID's
      for (var i = 0; i < ids.length; i++) {
        $(ids[i]).closest('tr').remove();
      }
    });
  </script>

  <?php
}

add_action( 'admin_footer', 'remove_user_fields' );
