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:

The correct answer choice would be B. 4 acetyl CoA enter the citric acid cycle.
Answer:
The correct labels are :
Label A prophase
Label B metaphase
Label C anaphase
label D telophase
Explanation:
Mitosis, a method of cell division which complete in four different phases. These phases are prophase, metaphase, anaphase and telophase. In the given question the correct labels are: A-prophase; B-metaphase; C-anaphase and D-telophase. Mitotic division is begins with prophase in which chromatin threads condense and called chromosomes. During metaphase all the chromosomes get arranged in the central plane. In the anaphase, the sister chromatids of each chromosome gets separated and move to the opposite pole. In the telophase the spindle breaks from the chromatids and begins to disappear. The nuclear membrane starts to form around each of the daughter chromosomes.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.
