The amazing process begins with the female digging a hole in the gravel with her tail. A female salmon will lay a few thousand eggs in the hole that will be fertilized by the male fish. Eventually the new baby salmon hatch out of these eggs.
D .............. im pretty sure its this one :)
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.
Ferns make their own food. They grow and reproduce using spores instead of things like seeds. Humans on the other hand have to ingest food from their surrounding and when mature reproduce sexually. They can also choose if they want to reproduce or not while ferns don't have that option. Sexual reproduction is based on inseminating and egg cell, while ferns don't worry about this because the spores just fall on the ground.
The right answer for the question that is being asked and shown above is that: Aerobic Respiration by definition is<span> the process of producing cellular energy involving oxygen. If </span><span>the aerobic respiration process broke down in a tropical rain forest, then the tropical rain forest cannot produce foods.</span>
