Q: Renal pyramids (or malpighian pyramids or Malpighi's pyramids named after Marcello Malpighi, a seventeenth-century anatomist) are cone-shaped tissues of the kidney. In humans, the renal medulla is made up of 10 to 18 of these conical subdivisions. The broad base of each pyramid faces the renal cortex, and its apex, or papilla, points internally towards the pelvis. The pyramids appear striped because they are formed by straight parallel segments of nephrons and collecting ducts. The base of each pyramid originates at the corticomedullary border and the apex terminates in a papilla, which lies within a minor calyx, made of parallel bundles of urine collecting tubules.

Based on this passage, why do renal pyramids have a striped appearance?
A: because they are formed by straight parallel segments of nephrons and collecting ducts

Stream of consciousness: To answer this question, we should know that: Jadzia is murdered in "Tears of the Prophets", the finale of the sixth season.

Q: Context: Jadzia is murdered in "Tears of the Prophets", the finale of the sixth season. She and Worf had been trying to conceive, despite the doubts of Dr. Bashir that such a pregnancy was possible. After Major Kira tells Jadzia she has been praying for a conception, Jadzia receives encouraging test results from Julian, and goes to the station's temple to thank the Prophets. It now appears a pregnancy will be possible. The Cardassian Dukat arrives, possessed by a Pah-wraith, with the intention of destroying the orb-like Bajoran artifacts known as the "Tears of the Prophets". Jadzia is no match for Dukat while he is infused with the Pah-wraith. He mortally wounds her and destroys the orbs. Upon her death in the infirmary, a distraught Worf screams out a Klingon wail of sorrow for his beloved and to let the Klingon afterworld know a warrior was on the way ("Heart of Glory"). Her death shakes the crew to its core: by the beginning of season 7, Sisko has left the station in despair and Worf has been risking his life on increasingly dangerous missions.
