Answer:
Baleen is a filter-feeding system inside the mouths of baleen whales. The baleen system works by a whale opening its mouth underwater and taking in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales.
Depending on the species, a baleen plate can be 0.5 to 3.5 m (1.6 to 11.5 ft) long, and weigh up to 90 kg (200 lb). Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness.[1][2] Baleen plates are broader at the gumline (base). The plates have been compared to sieves or Venetian blinds.

Answer:
In carbondioxide
Explanation:
During cellular respiration, the glucose is oxidized in the presence of oxygen and produce byproducts in the form of carbon dioxide and water. So when glucose with radioactive carbon is fed to mice then the radioactive carbon in glucose will be found in the carbon dioxide after respiration because the 6 carbon atom in glucose converts into 6 carbon atom of CO2 in the respiration process.
Cellular respiration reaction:
C6H12O6 + 6O → 6CO2 + 6H2O
Therefore we can find radioactive carbon atoms in the carbon dioxide after the mice completely oxidize the glucose in cellular respiration.
