Answer: adaptive immune response
Explanation:
Autoimmune disorders are caused by different microoorganism and drug which manipulates the immune system in a way that immune system become unable to recognise between self antigen and foreign antigen. In that case immune system treats foreign antigen as self antigen which cause systemic or organ specific damage.
The exact cause of autoimmune disorders is unknown and hence it is thought that it is caused by adaptive immune response which builds against self antigens and causes damage to the cells.
Hence, some autoimmune disorders are thought to be caused by adaptive immune response.

Answer:
<em>The chromosome number will not be constant and the person would die.</em>
Explanation:
During gamete formation, half of the chromosomes arise from one parent and the other half from the other parent. This is possible due to the process of meiosis.
If during gamete formation, the number of chromosome does not get reduced, then after fertilization the gamete will have double the number of chromosomes as compared to the parents. Hence, the chromosome number of the person will not remain constant and he/she would die.
Answer: Photosynthesis
Explanation: Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
