When someone bitten by an alpha werewolf continuously for 60 seconds, 250 g of the venoms will enter his or her body, get into the whole-body system and leave the body through sweats and urine, together with the blood, sweats and urine itself.  

A teenage dating couple at the side of the forest were suspected to be bitten by an alpha werewolf. One of them turn to be a beta werewolf and able to be captured, and another one was found dead. You are the expert chemist in werewolf study and are required to report your findings. Within your knowledge, if the venom leaves the body through urine and contains 1 wt% more than the urine itself, the victim will die but not for the case of venom leaving the sweats. However, if the overall venom leaves the body (through urine and sweats) are higher than the urine, the victim will turn into a beta werewolf. Nothing will happen if the overall body fluid in the victim's body is 99.5% higher than the venom itself.  

The followings are the details of the victims

1. Derive mass balance independent equations to reflect the following situations:  
2. If the male becomes beta werewolf, and the female died (Team 1, 2) 
3. If the female becomes beta werewolf, and the male alive (Team 3, 4) 
4. If the female alive, and the male becomes beta werewolf (Team 6) 
5. Both become werewolf (Team 7,8) 
6. Both are dead (Team 9) 
7. Both are alive (Team 10)
