The right answer is B

A radiotracer is an entity composed of a carrier molecule and a detectable radioactive isotope using devices such as gamma cameras or positron emission tomography.

A radiotracer is either a radioactive isotope alone or the combination of a molecule and a radioactive isotope. In this case, it is said that the molecule is labeled by the radioactive isotope.

A radioactive isotope is an atom whose nucleus, unstable, emits radiation. It could be :

- alpha radiation consisting of two protons and two neutrons.

- a beta radiation consisting of a negative electron (beta) or a positive electron (beta +, positron).

- a gamma radiation consisting of a high energy photon.

Art [367]

Answer:

Stop habitat destruction

Explanation:

Cutting down and burning forests basically take away the shelter, hunting grounds, and overall habitat away from many species that use the trees as a form of shelter and protection. Removing their shelter, which could be their only form of protection causes many of these organisms to die, not to mention the plants that are necessary to keep the food chain balanced.
