The most common use of radioactive isotopes in medicine is to diagnose disease. Typically, radioactive materials are injected into the body and then radiation-detecting cameras are used to build images of affected body parts or particular types of cells. This equation models the amount of a radioactive isotope in the bloodstream minutes after it is injected:
Radioactive substances are employed in therapy to destroy malignant tissue, shrink a tumor, or lessen discomfort.
What is the radioactive elements?Two or more chemical species of an element with varying atomic masses and unstable nuclei are referred to as radioactive isotopes. Because of the excess radiation that these isotopes produce in the form of alpha, beta, and gamma rays.
Nuclear medicine treatments use a tiny amount of radioactive substance called a radiopharmaceutical to assist diagnose and cure disorders. To identify disorders, some radiopharmaceuticals are utilized in conjunction with imaging technology. To reduce or eliminate a cancerous tumor, radiopharmaceuticals can also be injected close to the tumor inside the body.

A population of mice thrive when grain and seed resources are plentiful. When food runs out, they compete with
one another for food and no longer produce offspring. This is an example of
O biotic potential
O group behavior
O individual behavior
O interspecific competition
individual behavior
Explanation:
if the mice are competing with each other that means that it's every man for himself.
The given example suggests the individual behavior of the mice because they change their behavior according to conditions.
How a population of mice affects the resources?In nature, organisms search for resources first, and if this availability is fulfilled, they reproduce themselves and increase the number of offsprings, but when the availability of resources are depleted they compete with each other.
The individual behavior of the mice in the population is defined as some mice fighting for the same resources and others mating with each other.
In the given question interspecific competition is not a right choice because it is the competition between the organism of two different species for the same resources.
Therefore, option C is correct.

How does water move from the biosphere to the atmosphere in the water cycle
Answer:
The water cycle depicts the ongoing circulation of water inside the Earth and atmosphere. It is a complicated structure with several functions. Water vapor evaporates from liquid water, compresses to create clouds, and falls back to earth as rain and snow.
Explanation:
The water cycle is a cyclical process in which water circulates between the earth's atmosphere, seas, and surface via precipitation, drainage in lakes and rivers, and return to the earth's atmosphere by absorption and evaporation. Throughout respiration, organisms exhale carbon dioxide and water vapor, which evaporates back into the atmosphere.
