Oxygen-16 and Carbon-12 are stableisotopes of elements O and C respectively. Hence, they do not have half-lives. But Carbon-14 andUranium-238 are radioactive isotopes. Among them Carbon-14 has relatively short half-life as about 5730 years while Uranium-238 has a long half-life as about 4.5 billion years.
Answer is. uranium-238
Answer:
c. are often quite different from each other
Explanation:
Multicellular organisms - composed of several different cells: Cells in these organisms differ in relation to the function to be performed.
The cells in these organisms are growing, developing, and reproducing.
The cells differ in shape, size, and role they have in the organism.
In the group of multicellular organisms are animals (Animalia), plants (Plantae), and fungi (Fungi).
The principles of probability can be used to predict the outcomes of genetic crosse
The items needed to complete a circuit include the following:
<h3>Functions of the parts of a Circuit.</h3>
The wire helps in the distribution of the electric current from the power
source in order to ensure it gets to the load.
The battery contains compounds which is responsible for providing the
energy required to power up the load.
The load could be a bulb, fan etc and is the final destination of the electric
current. The electric current powers up the load and makes it functional.
The switch helps to regulate the flow of electric current and has an 'on and
off button' to prevent energy wastage when not in use.
