B.) the available food on the islands
Since these different beaks were adaptions part of their evolution to be able to be more fit to survive with the food available on the island
A nonnative species may not have any natural predators when being introduced subsequently it won’t have any competition with the other organisms living in the same ecosystem. This will make the other organisms struggle for food and other resources and could potentially make them go extinct. They can also have drastic effects to the local biodiversity (for the previous reason). Also, due to the competition or newly introduced predator (assuming they’re a predator) the preexisting organisms of the ecosystem may start to relocate and start a new ecosystem or if there are neighbouring towns/cities may have to forage for food there - which would obviously be dangerous for both them and us. Hope these few examples help.
When sodium chloride is formed from a positively charged sodium atom and a negatively charged chlorine atom, the charge on the salt becomes neutral is true
Explanation
Sodium ion ( positively charged) combine with chloride ion ( negatively charged) to sodium chloride which is neural according to equation below.
Na⁺ + Cl⁻ → NaCl (<em>neutral</em>)
Equal number of positive and negative charges add up to make neutral Nacl therefore the statement above is true.
C. The nucleus does not exit within a prokaryotic cell
The answer would be conservative plate boundaries.
They occur where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake.
I hope this helped and is correct! :)
