The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.
Primary succession can occur in essentially lifeless areas or regions in which the soil is incapable of sustaining life as a result of such factors as lava, sand dunes, or rocks left from a retreating glacier.
The correct answer is nephron.
<span>
The nephron consists of Bowman’s capsule ( where blood is initially filtered ) and glomerulus which is a tuft of capillaries. Bowman’s capsule and a glomerulus together form the renal corpuscle. The renal tubule extends from the capsule and it consists of proximal convoluted tubule (selective reabsorption), a loop of Henle (establishes a salt gradient) and distal convoluted tubule (selective reabsorption). </span>
