<u>Answer</u>:
When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.
<u>Explanation</u>:
In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.
As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.

The fingernails on the manatee are homologous structures.
Explanation:
The manatee is an animal that lives in the water, but it is not an animal that is related to the fish, instead it is a mammal. When the term mammal is mentioned, people often think of terrestrial animals, but some of the mammals are not living in the water, and have lot of characteristics that are very similar to the other marine animals. Mammals that live in water are:
Some of these mammals, like the manatee, actually have fingernails, which is very weird considering that they are of no use. The fingernails are actually homologous structures, or rather structures that have been kept from their ancestors, and can be found at many other animals with which they share common ancestor. While the ancestors of the manatee were terrestrial mammals, over time they totally transformed as they were using the water more and more, but the fingernails remained, with the main reason for that being that they are not disadvantageous, so there is no evolutionary pressure for the animal to lose them.
