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
Lactose because it is a sugar made up of galactose and glucose.
The probability of producing a transgender = None ( D ) when the father is gay

Answer:
In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.
Explanation:
During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.
In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.
