Earthworms are delicate. Careful handling is important to
avoid damaging the internal organs.
Place the worm with the dorsal side up. Start the dissection
2 centimeters posterior the reproductive segment. Snip the skin above the dorsal blood
vessel ( near the posterior pin) through
the septa to the mouth.
This is known as carbon.
Any atom with 6 protons is carbon. The number of electrons determines whether it is an ion and the number of neutrons determines which isotope it is and contributes to the atomic weight.
Hope this helps!
Answer:
granular cells of the juxtaglomerular apparatus
Explanation:
Renin or angiotensinogenase is a circulating enzyme released by granular cells of the juxtaglomerular apparatus of the kidney in response to a series of physiological stimuli and causes activation of the renin-angiotensin-aldosterone system.
Renin transforms angiotensinogen from the liver into angiotensin I, which is transformed into angiotensin II by the lungs.
