Answer:
<h2>D. Joan of Arc</h2>
Explanation:
Joan of Arc was a French peasant who claimed she'd had visions of saints and an angel that told her to help restore France from domination by the English.
Joan of Arc came to the scene at a critical time in 1429. The northern half of France was essentially under the control of the English. There was contention over who was truly the French king after Charles VI had died in 1422. His son, the prince Charles, was a claimant to the throne. But the English contended their boy king, Henry VI, should rule over France.
In January 1429, Joan (age 17) came to the court of the prince, Charles, and convinced him of her mission from God. Within a few months, she had rallied the people of France and helped to break the control of the English over large sections of French territory. She ultimately was captured by a group of French nobles who were allied with the English, was handed over to the English, and was burned at the stake (in 1431). But she had done much to unite the French people around a sense of common patriotism and national aspirations.
Nutrients primarily come from detritus sinking from more productive shallower water.
<h3>Define detritus.</h3>
In contrast to dissolved organic material, detritus is dead organic material that is in the form of particles. Detritus typically consists of faces and the carcasses or remains of dead organisms. Communities of microbes that colonize and breakdown (i.e., remineralizer) detritus are frequently found in it. It is known as "soil organic matter" and is present in terrestrial ecosystems as leaf litter and other organic matter that is combined with soil. Organic matter that is suspended in water and accumulates in depositions on a body of water's floor referred to as "marine snow" when the floor is a seabed is referred to as detritus in aquatic ecosystems.

Explanation:
More specifically, porosity of a rock is a measure of its ability to hold a fluid. Mathematically, it is the open space in a rock divided by the total rock volume (solid and space). Permeability is a measure of the ease of flow of a fluid through a porous solid.
