Explanation:
In cellular respiration, animals take in O2 (oxygen) and exhale CO2 (carbon dioxide).
 
        
             
        
        
        
Answer:
A. Cyanobacteria.
Explanation:
Both cyanobacteria and plants use water as an electron donor for the light phase of photosynthesis and make ATP and NADPH. The ATP and NADPH are used in the Calvin cycle to fix the atmospheric CO2 into glucose. The use of water as an electron donor releases oxygen gas as a by-product. This photosynthesis wherein the use of water as an electron donor releases oxygen gas as a by-product is also called oxygenic photosynthesis.
 
        
                    
             
        
        
        
<span>The answer would be: a. inflammation is accompanied by an increase in peristaltic movements of his small intestine.
The pathogen will attract the white blood cells that will induce inflammation in the intestine. Inflammation of the intestine will cause increased permeability and increased bowel movement, makes the food transit time reduced and lead to diarrhoea. This mechanism is beneficial since it can help the intestine to "flush out" pathogen of toxins that induce the inflammation.</span>

According to the climate change, the correct order is : 
<span>1 - Sources emit greenhouse <span>gases.
</span></span>CO₂ makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of CH₄ and nitrous oxide N₂O are also <span>emitted
</span><span>
2- </span>Global temperatures rise.
 Temperatures measured on land and at sea for more than a century show that Earth's globally averaged surface temperature is rising<span>.
</span><span>
3- </span>Snow and ice melt.
If the surface temperatures warm above 32°, the snow and ice touching the surface will warm and begin to melt<span>. 
</span><span>
4- </span>Sea levels rise.
When sea levels rise<span> rapidly, as they have been doing, even a small increase can have devastating effects on coastal habitats.</span>
