Answer: The correct sequence for the series of event would be.
1. Igor's toe is being cut by the glass.
2. The wound surrounding the injury becomes infected  with bacteria from Igor's foot.
3. Antibodies and circulating white blood cells stick to the  bacteria creating a large complex in the lymph vessel.
4. The bacteria enter his lymph system and travel towards a lymph node.
5. The complex becomes trapped in a lymph node and is  engulfed by a phagocyte.
6. The bacteria is destroyed.
Explanation:
Whenever there is any cut or wound in the body and body encounters invasion of the foreign materials it considers it as harmful pathogen.
These pathogens when enters the body it is considered as antigen, it then travels to the lymphatic system.
These bacterial complex is then killed by the phagocytes and digested by the body.
In this way the complex is killed and the bacteria is destroyed. 
 
        
             
        
        
        
Answer:
Explanation:
Heat required to convert ice to ice at 0⁰C
= mass x specific heat x rise in temperature 
= 18 x 2.09 x 20 
= 752.4 J . 
heat required to convert ice at 0⁰C to water at 0⁰C
mass x latent heat of fusion
= 18 x 336 
= 6048 J 
Heat required to increase the temperature of water to 100⁰C 
= 18 x 4.2 x 100 
= 7560 J 
Total heat required 
 7560 + 6048 + 752.4 
= 14360.4 J
