How do cells get ATP through Cellular Respiration.
Cellular respiration takes place in the mitochondria. The Mitochondria use oxygen (O2) to convert broken-down glucose (at type of sugar) into carbon dioxide (CO2) and water (H2O).
The reactants of CR are oxygen and glucose.
The products of CR are ATP, carbon dioxide, and water.
Alfred Wegner was the first person to propose the idea that all seven continents were all one supercontinent called "Pangea". Everyone considered his theory to be a joke until he found evidence to back up his theory. His evidence was the matching mountain ranges, fossils, certain species, and more over different continents. Also that all the seven continents fit together like puzzle pieces. I hope this helps! :)
Over the last few days, NASA has been getting everybody excited with its plans to hold a high profile briefing about a discovery beyond our solar system. Now we know that the announcement concerns the discovery of seven planets orbiting a star elsewhere in our galaxy<span>. hope this helps</span>
Work = -Pressure external*Volume change
<span>-1 atm * (20 - 1) = -19 atm-L. </span>
<span>1 atm-L = 101.324999971 J </span>
<span>So -19 * 101.32 = -1925 J </span>
<span>B. </span>
<span>Calculate each step individually then sum the answers. </span>
<span>For step 1) </span>
<span>-5 * (4-1) = -15 atm-L </span>
<span>step 2) </span>
<span>-1 * (20-4) = -16 atm-L </span>
<span>Thus total work = -31 atm-L </span>
<span>convert to joules, </span>
<span>-3141 J</span>
