Commonly called the enterics due to the fact that they inhabit the intestinal tracts of humans and other animals.
Solar energy is energy that comes from the sun and is captured by solar cells. These cells transform the energy of photons of light into electrical energy. One mechanism is the energization of electrons, here the energy of the photons is transferred to the electrons, which can already be considered electric energy.
As for the hydroelectric energy, here the waterfalls or rivers flow driving a turbine, which will transform the movement into usable electric energy as it rotates.
The answer Is B A new Species is forming
Hello!
There are two possible answers to this. The one I'm assuming you're looking for is hydrogen bonds.
Hydrogen bonds are the bonds which hold together the double helix shape of DNA. These bonds result from a positive and negative charge drawing two molecules closer to each other. These bonds are generally seen as weak, however, since there are so many of these bonds (as there are so many nitrogenous bases in one strand of DNA), the double helix strand is fairly strong.
Hope this helps!
