Answer:

Sprinter hold their breath while marathon runner didn't.

Explanation:

A sprinter can use mainly anaerobic respiration during the race because a sprinters hold their breath during a race so due to lack of oxygen it takes energy from anaerobic respiration, while a marathon runner needs to use aerobic respiration because he use oxygen during their race and by using oxygen aerobic respiration is executed. So we can conclude that sprinters use anaerobic respiration while marathon runner use aerobic respiration during running.

When the elodea is underwater where is the carbon dioxide coming from

astra-53 [7]

The elodea is getting the carbon dioxide from its environment like when underwater animals breathe out carbon dioxide the plants will use that carbon dioxide. The plants can also get the carbon dioxide from the atmosphere which can "dissolve" in water.

Using the help of the semi concevative replication of DNA, what is the role of a single strand of DNA

miss Akunina [59]

Answer:

In the semi-conservative method of DNA replication, each of the strands of the double helix acts as a template for replication.

Explanation:

Semi-conservative DNA Replication:

Semi-conservative DNA replication produces two daughter helices from the original parent helix. One strand of the daughter helix is form the original template while the other is newly synthesized.
This means that one strand will have the base sequence identical to the parent, while the other will be complementary to the template.
This model was experimentally confirmed by an experiment conducted in 1958 by Meselson and Stahl. They used radioactive isotope of nitrogen i.e. N-14 or N-15. DNA molecules made with N-15 were allowed to replicate in the presence of N-14.
After first replication, DNA molecules contained both N-15 and N-14 isotopes, disproving the conservative model that stated that the new helices are completely identical to the template.
The second replication yielded only N-14 which disproved the dispersive model that the new helices are a combination of both the template and new strands.
