B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.
The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.

Answer:
B. the genetic diversity of the crops will decrease
Explanation:
without the influence of the insects, the crops will have no reason to change
Betta fish are also known as Siamese fighting fish.They flare their gills when they are ready to fight. This makes them appear larger since fish do not have very good eyesight. They also fan their gills when they are trying to court a female Betta. ... Bettas are one of the few fish that can get air from above the water.
Answer:
Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.
Explanation:
For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.
When you put water onto water, it's an addition of water, you don't say it's wet or wetter.
Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.
Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.
So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
There are many fuels that produce energy. Some are:
- Coal
- Nuclear Energy
- BioFuel
- Oil / Gas
Hope this helps!
