Answer:
New species can appear gradually through small changes in an ancestral species.
Explanation:
The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
Answer:
Falso
Explanation:
La ecología es <u>la ciencia que estudia la interacción entre los seres vivos y el ecosistema.</u> Esto incluye la interacción entre todos los factores tanto bióticos, o vivos, como abióticos, no vivos.
Por ejemplo, la ecología podría estudiar la manera en que un venado interactúa con su entorno: cual es su principal fuente de alimento, el rol que juega en el ecosistema, las adaptaciones que ha desarrollado para vivir en dicho entorno, etc.
Debido a que la materia inerte es considerada un factor abiótico o no vivo, esto no correspondería al área de la ecología. Por ende, este enunciado <u>es falso</u>.
The phase contrast microscope uses out-of-phase and in-phase light rays that produce contrast areas allowing scientists to detect even a minute number of protein molecules and focus on the minute internal structures of a particle.
