Answer:
A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule
Explanation:
Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.
However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.
This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.
1- C ( this is an assumption; a hypothesis is always based on an assumption.
2- F ( this states to share the results with other classmates).
3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.
4- A (this is something you could observe during the experiment, therefore it is an observation).
5- E (this sentence is a conclusion).
6- B (This is an actual question)
The coexistence of eight species of woodpeckers in Oregon forests is an example of
Resource partitioning
Number B is the correct number
ATP is the cell's energy, the mitochondria (aka the power house of the cell) is what produces ATP. The process is called Cellular Respiration.
