Answer:
Option A
Explanation:
Only an autotrophic species can convert methane into food.
Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.
Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.
Hence these autotrophic bacteria’s will be considered as producers as they produce food.
Thus, option A is correct.
Patient A is suffering from anemia, due to underproduction of hemoglobin
Explanation:
Patient A’s blood cell count:
Hemoglobin: 5g/dL
RBC: 4.6 x 106 cells/ml
WBC: 15,000 cells/ml
Platelets: 250,000
Results inferred from the count: Low hemoglobin, low normal RBC, high WBC, normal platelets count
Hemophilia is an inherited blood clotting disorder, where due to excessive bleeding, blood hemoglobin, RBC, and platelets can go lower. The low hemoglobin is due excessive loss of blood and not due to underproduction of hemoglobin. Moreover, patient A’s platelet count is normal. Hence, hemophilia can be ruled out.
Since the hemoglobin and RBC count is low, it clearly indicates low production of these blood cell components, leading to anemia. However, the increase in WBC leads can be due any other underlying medical conditions like infections, hemolytic anemia, leukemia etc.
