The correct answer is B. All species share a common ancestor and that change occurs through time.
We can see this because the diagram start at one point (the common ancestor) and spreads out in different ways (changes throughout time).
I hope this helps u!
Have a great day! :)
Answer:
Una de las características de los seres vivos se encuentra en su composición biológica, dado que todos ellos están constituidos por cuatro bioelementos esenciales que se encuentran de manera abundante en la naturaleza:
Carbono
Hidrógeno
Oxígeno
Nitrógeno
Estos bioelementos o elementos biogénicos están presentes en las biomoléculas, que son las que dan forma a la materia que constituye a los seres vivos. Estas moléculas están formadas, a su vez, por la unión de átomos.
De estos bioelementos, es importante destacar el papel del hidrógeno y el oxígeno, que dan lugar a la molécula del agua. El agua, o H2O, juega un papel fundamental en el funcionamiento de los seres vivos.
Nucleotides makes up each individual strand of DNA
Answer:
translucent
Explanation:
Transparent means ALL light and ALL shapes are visible through, like a window.
Pigmented means that shapes are visible clearly, but not colors, like sunglasses.
Translucent means that shapes are somewhat visible (v. blurry,) and lights are somewhat also.
opaque is nothing in, nothing out. Solid.
Explanation:
Molecules of reactants and products undergoes chemical changes when they combine.
The combination leads to the breaking of bonds and rearrangement and this brings about the formation of new products.
- Atoms in molecules tends towards stability
- They often want to mimic the noble gases and would keep rearranging until stability is attained.
- This leads to the formation of new compounds in the product end of the reaction.
