Problem:OPTIONS:
- tracheophyte stage
- zooflagellate stage
- zygum stage
- diakinesis stage

Answer the following question given this paragraph: During the diakinesis stage, chromosomes further condense. The chiasmata remain intact during this stage. The remainder of this stage is similar to prometaphase of mitosis: the nucleoli disappear, the nuclear membrane disintegrates, and the meiotic spindle begins to form. Q: Chromosomes further condensed in which stage? A:
****
A: diakinesis stage

Answer the following question given this paragraph: Renal Hilum The renal hilum is the entry and exit site for structures servicing the kidneys: vessels, nerves, lymphatics, and ureters. The medial-facing hila are tucked into the sweeping convex outline of the cortex. Emerging from the hilum is the renal pelvis, which is formed from the major and minor calyxes in the kidney. The smooth muscle in the renal pelvis funnels urine via peristalsis into the ureter. The renal arteries form directly from the descending aorta, whereas the renal veins return cleansed blood directly to the inferior vena cava. The artery, vein, and renal pelvis are arranged in an anterior-to-posterior order. Q: The renal hilum is the entry and exit site for structures servicing which organs? A:
****
A:
kidneys
