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.

The process by which ions join to reform the solid is called dissolution
mestny [16]
I believe the process by which ions join to reform the solid is called precipitation. It is a process in which ions leave a solution and regenerate an ionic solid. For example; Ag+(aq) + Cl-(aq) = AgCl (s). Dissolution on the other hand is the process in which an ionic solid dissolves in a polar liquid; it is the opposite of precipitation.

Organisms use different types of adaptations to aid in their survival. many different types of animals hibernate throughout the
zalisa [80]

Option (A) Torpor is the correct answer

Organisms that undergo hibernation have the ability to slow down their metabolism so as to lower the core temperature. This process is known as Torpor.

<h3>Why is torpor important for organisms undergoing hibernation?</h3>

Torpor is a state in animals where they lower all their metabolic activities and bodily functions so as to keep the body temperature low.

It is done by the animals to conserve resources in conditions where scarcity of food is there.

Some birds undergo torpor to conserve fat in the body.

Some animals use this technique of torpor to survive competition with other species.

These organisms come back to normal physiology when the conditions become favorable.

What kind of model is a globe and what are its limits
tester [92]

A model of a globe is a physical model. The limits are that the solar system is too big to be seen all at once. From the Tennessee science textbook, "Many years ago, scientists thought that Earth was the center of the universe and the sky was a blanket that covered the planet. Later through the observation, it was discovered that the objects you see in the sky are the sun, the moon ,stars, and other planets. This new model explained the solar system differently.
