<span>A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel, monitoring the process to detect when the concentration of aqueous ammonia in the second reaction vessel has fallen below the selected range, and feeding aqueous ammonia solution with an ammonia concentration in or above the selected range to the second reaction vessel to return the solution to within the selected range.</span>

<u>Answer:</u> transitional
<em>Gerobatrachus hottoni mostly like to be transitional fossil.</em>
<u>Explanation:</u>
<em>Gerobatrachus refers to an extinct genus of amphibamid temnospondyl, which thrived in the initial Permian, that is, about 290 Mya</em>, in the region, which is now known as Baylor County, Texas.
The transitional form of fossils is those that <em>demonstrate the intermediate form between the two distinct living species, </em>it could be in a form of an ancestor and its descendants.
It has been believed that the reptiles creatures as frog have evolved from the <em>previous ancestor of primitive amphibian tetrapod subclass known as Temnospondyl. </em>
Answer:
Tropical climates are better suited for a multitude of species of plants and animals.
Explanation:
The reason for this is tropical climates are easier to handle then harsh winters because almost all tropical climates are near the equator so it tends to stay warmer year round creating a year round growing period. Polar climates are harsher on the plants than the animals. Also consider this the fact that there would be no herbivore animals for predators to eat so that limits what can grow in the polar climates.
The one that best help the scientists to study the generation of Earth's magnetic field would be : A. Comparison rotation of the earth's core and Crust
The Earth's magnetic field currently tilted at the angle of about 10 degrees with respect of Earth's rotational axis
hope this helps
