During meiosis i, the homologous chromosomes of a tetrad face the same spindle pole. face both spindle poles. face opposite spindle poles. do not face spindle poles, but are aligned at the spindle equator. undergo separation of sister chromatids.

Face opposite spindle poles

Explanation:

Meiosis is a kind of cell division that involves the formation of daughter cells with a reduced chromosomal number (by half). Since the chromosome number is reduced, it occurs in a two step division process viz: Meiosis I and Meiosis II. In meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) separate.

In the Metaphase stage of meiosis I specifically, spindle microtubules from opposite poles of the cell attaches to the kinetochores of each chromosome and aligns them at the equator. This alignment is done in such a way that each homologous chromosome of a tetrad or bivalent (pairing of homologous chromosomes) faces opposite spindle pole in order for their separation to opposite poles in Anaphase to be accomplished.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
