True!
Arteries carry oxygen-rich blood from the heart to capillaries. On the contrary, veins carry blood without oxygen from the capillaries to the heart.
Arteries are very flexible and yet strong blood vessels so efficient transport of oxygen-rich blood through the organism is performed.
Vasapore is nt considered a part of the nale urethra. Only the other options are.
The main two functions of a catalyst are to
1) Decrease reaction activation energy
This is accomplished by providing the reaction with an alternate pathway which does not require as much activation energy.
2) Decrease reaction time
This is done by decreasing the activation energy as well as arranging substrate molecules in a manner in which they are easily broken down.
The molecules of nitrogen in the urine are broken down into ammonium. - Step 5 ("Nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification<span>.")
Then, ammonium is converted into nitrates by nitrifying bacteria. - Step 1 ("</span><span>Ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. This is called nitrification.")
There are then two ways that the cycle can take... in the one related to the deer, follows the assimilation where the plants add the nitrogen to protein. - Step 6 ("</span><span>Plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.")
The deer then eats the plants and the nitrogen is again inside it and ready to be used and again released in urine. - Step 2 ("</span><span>The deer eats the plants and uses the nitrogen-containing proteins for cell growth.")
The other way that the nitrogen may take is denitrification by denitrifying bacteria. - Step 4 ("</span><span>Some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere.")
This gas is then captured by nitrogen fixing bacteria, called nitrogen fixation. - Step 3 ("</span><span>Bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium.")
The ammonium is now ready again for t</span>he process of ammonification.
