The part of the nephron that In which part of the nephron are sodium and chloride ions are actively reabsorbed is the Henle's loop. It <span>is the portion of a </span>nephron<span> that leads from the </span>proximal convoluted tubule<span> to the </span>distal convoluted tubule<span>.</span> It's main function is to make a concentration gradient in the medulla of the kidney. 
        
             
        
        
        
Hey there,
Step 1: N<span>ever attempt to remove a patient from an electrical source unless the EMT is trained and equipped to do so.
Step 2: </span><span>Never touch a patient who is still in contact with the electrical source
Step 3: </span><span>Administer oxygen by nonrebreather mask at 15 lpm
Step 4: </span><span>Monitor the patient for cardiac arrest
Step 5: </span><span>Assess the patient for muscle tenderness with or without twitching and any seizure activity
Step 6: A</span><span>ssess for an entrance and exit burn injury
Step 7: T</span><span>ransport the patient as soon as possible.
Hope this helps :))

I don't think changing seasons can REMOVE CO2 from the air, but I do think instead it could add it to the air. It's a long process that involves several ecosystems and stuff. But, as the climate is getting warmer, ice caps are melting and within these ice caps... there are trapped bubbles of CO2 that are released ( I am not sure if this adds a lot of CO2 to the atmosphere, but I am sure that it does contribute to CO2 concentration). 
In relation to your last statement... plant growth would actually reduce CO2 in the air because of the process of photosynthesis. Plants take in CO2 and give out O2 for us to breathe. In turn we conduct cellular respiration in which we take in the O2 and give out the CO2. So, plants are actually one good solution for decreasing CO2 levels.
