The answer would be B for this question. ATP is used by the mitochondria the “power house” of the cell.
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs, and have no body symmetry.
The shapes of their bodies are adapted for maximal efficiency of water
flow through the central cavity, where it deposits nutrients, and leaves
through a hole called the osculum. Many sponges have internal skeletons of spongin and/or spicules of calcium carbonate or silicon dioxide. All sponges are sessile
aquatic animals. Although there are freshwater species, the great
majority are marine (salt water) species, ranging from tidal zones to
depths exceeding 8,800 m (5.5 mi).
<u>Answer: </u>
Option(D)
Powder Alarm
<u>Explanation: </u>
The powder alarm was a considerably prominent reaction to the orders of General Gage, royal governor to the British soldiers to remove the gunpowders from the magazine.
In response to this action, amid rumours that blood had been shed, alarm scattered to Connecticut and even beyond through the countryside, and American Patriots sprung into action, fearing that war was at hand.
<span>The protons want to diffuse into the mitochondrial matrix and they do this by going through the ATP synthase protein which resembles a water turbine. As the protons move through the ATP synthase, ATP is produced. In essence the energy from H+ wanting to diffuse through the inner mitochondrial membrane is converted to energy in the form of ATP</span>
