YHH i said that it doesnt need to be repeatedly applied like pesticide, it doesnt lead to bio accumulation, and its specific to one organism

Yh exactly the same, except I put that the pest cannot become resistant to the biological control. Apart from that question on the waterlogged soil (where I put the osmosis 😭😭😭), it was fine. The 8 marker and the 6 marker were heavenly tbh

i said that the person may have blood cancer or an infection - most likely an infection bc an infection leads to an immune response so more lymphocytes/antibodies idk tho
