Blue whales are mammals and just like us have lungs with alveoli and transport oxygen in blood via a closed circulatory system. However, in contrast to us, blue whales are the biggest animals that have ever lived. Compared to a human, the total distance that oxygen has to diffuse to reach cells in blue whales is blank , while the distance of bulk flow for oxygen in blue whales is

Roughly the same, larger.

Explanation:

The mammals have four chambered heart and double circulation occurs in mammals that separates the oxygenated and deoxygenated blood in mammals and saves the energy.

The oxygen needs to diffuse in each and every cell of the body. The distance of the oxygen diffusion is almost same in the whales and other mammals. The distance of bulk flow of oxygen depends on the total surface area and inversely proportional to it. The humans body small is small as compared to whales and has less distance where blue whale has the large distance of bulk flow for oxygen.

Thus, the answer is roughly the same, larger.

the answer to this predicament is false, by friend, i had this on a quiz, and i got it wrong, so i learned it, cos i was gonna have it on a test, and i got it right

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
