Answer:
D. the homologous chromosomes are paired AND the spindle is formed
Explanation:
Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.
In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.

Hydrogen ions rush out of the thylakoid, powering the reaction that produces ATP
Explanation:
As the electrons from the reactive center of photosystems are passed down the protein chain, their energy is harnessed to pump in H+ ions from the stroma into the thylakoid lumen. This creates an H+ proton gradient that has potential energy to do work. ATP synthase utilized this gradient to generate ATPs by chemiosmosis. As the H+ ions move down the concentration gradient through the protein molecule, the ATP synthase is able to phosphorylate ADP and convert them into ATPs – the energy currency of cells.
This same principle not only in the chloroplasts but also in the mitochondria.
