Describe the structure of the nephron and explain the role of each part of a nephron in creating urine (5 points)

Each kidney has approximately 1 million nephrons. Each nephron consists of 2 parts: 1. Glomerulus; 2. Renal tubules

Explanation:

The glomerulus is a capillary type branching network formed from the renal arterioles which originates from the renal artery and is involved in the filtration of blood.

Renal tubules has the following parts:

i) Bowman's capsule: It is a double layered cup like structure. Bowman's capsule along with glomerulus forms the malphigian corpuscle or renal body.

ii) Proximal convoluted tubule (PCT): It forms a highly coiled network.

iii) Henle's loop: It is hairpin shaped part of tubule which has a descending and an ascending limb.

iv) Distal convoluted tubule (DCT): It is also a highly coiled tubular region.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
