Explanation:
According to Lindeman's 10% law, only about 10% of the energy from one trophic level is transferred to the next; the rest is lost as heat through respiration. Producers (Trophic Level 1) have 10,000 kcal. Primary consumers (Level 2) get 10% of 10,000 = 1,000 kcal. Secondary consumers (Level 3) get 10% of 1,000 = 100 kcal. Tertiary consumers (Level 4) get 10% of 100 = 10 kcal.

Explanation:
The Philadelphia chromosome is a specific genetic abnormality found in the bone marrow cells of most patients with Chronic Myelogenous Leukemia (CML). It is formed by a reciprocal translocation between the long arms of chromosome 9 and chromosome 22, denoted as t(9;22). This translocation fuses the BCR gene on chromosome 22 with the ABL1 gene on chromosome 9, creating a mutant BCR-ABL1 fusion protein with constitutive tyrosine kinase activity, driving uncontrolled cell division.

Explanation:
Approximately 70% of CO2 is transported in the blood as bicarbonate ions (HCO3-). CO2 diffuses into red blood cells, where it reacts with water to form carbonic acid, catalyzed by the enzyme carbonic anhydrase. Carbonic acid then dissociates into H+ and HCO3-, which moves into the plasma. About 20-25% is carried as carbaminohemoglobin.
