Answer:

Option (B)

Explanation:

The Permian period started from 286 million years to 245 million years back.

It was the last period that belongs to the Palaeozoic era. During the initial stage of this period, the continents were all combined together, forming the supercontinent called the Pangea. The Pangea at this time experienced a very extreme type of climates because of its huge landmass and towards the south, the area was under the frozen ice. This period was the boundary that separates the Paleozoic and the Mesozoic era.

Towards the end of the Permian, there occurred a global mass extinction. As a result of which, about 90% of the earth's marine species and approximately 75% of the terrestrial lives were completely wiped off from the planet.

Thus, the correct answer is option (B).

Describe the flow of glomerular filtrate from its formation in bowman's capsule till it exits the body as urine
SOVA2 [1]
There are 3 main processes in urine formation. These are Filtration, reabsorption  and secretion. 
Filtration
Blood enters the afferent arteriole and goes to glomerulus where blood is filtered and it will sip inside the glomerulus and nonfilterable components will go into efferent arteriole.

Reabsoprtion
Molecules and ions will be reabsrobed into  the system. The fluid will pass into the proximal, distal and convoluted tubules, loop of henle, as water an ions are removed as the fluid osmolarty changes. Last is secretion of substance  that is not filtered.
