The answer is eukarya. While Eukarya, Archaea, and Eubacteria may share some similarities, the most distinctive feature of eukarya is the presence of a membrane-bound nucleus containing the cell's genetic information. This diverse group includes plants, animals, fungi, and protists (unicellular organisms).
Answer:
Its based the organism's observable traits
In simpler terms, the Big Bang theory says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius). The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.
The atomic number where as the atomic mass refers to the number of both neutrons and protons and the symbol refers to the element
Answer:
The correct answer is option A, the type of isotope
Explanation:
The half life of a radioactive substance is a constant value and thus it is not affected by the temperature, catalyst or mass of the substance. Basically it is the time taken by a radioactive substance to reduce its mass by half of its actual value. Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element.
