Answer:
2. Bowman's capsule
6. proximal tubule
1. descending limb of loop of Henle
4. ascending limb of loop of Henle
5. distal tubule
3. collecting tubule
Explanation:
There are two main components of a nephron-
a) Renal Tubule
b) Renal Corpuscle
Renal Tubule –
The renal tubule emerges from the glomerulus and consists of three sub parts
a) Proximal Convoluted Tubule (PCT)
b) Henle’s Loop – has descending and an ascending limb
c) Distal Convoluted Tubule (DCT) – last part of nephron
Renal Corpuscle- consists of a glomerulus surrounded by a Bowman’s capsule
So the correct order is as follows
2. Bowman's capsule
6. proximal tubule
1. descending limb of loop of Henle
4. ascending limb of loop of Henle
5. distal tubule
3. collecting tubule
72 chromatids were present in the present in the primary oocyte during prophase 1 of meiosis.
The primary oocyte contains 72 chromatids during prophase 1 of meiosis as the mature ovum has 18 chromosomes.
The primary oocyte contains 72 chromatids , that means it contains 144 chromosomes. During the first meiotic division, it produces one secondary oocyte and one polar body.
The secondary oocyte has 72 chromatids, which again undergoes second meiotic division and produces mature ovum and second polar body . The mature ovum contains contains 36 chromatids which means it has 18 chromosomes.
