Answer: The correct answer is -
D) giraffes having increasingly longer necks over time.
Natural selection is an evolutionary mechanism that was proposed by Darwin.
According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.
Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).
This is considered as a peculiar example of natural selection.

It is way better to develop because fungi is a useful product to the world.
Answer:
cada célula tendrá dos núcleos
Explanation:
El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.
