Stereomicroscopes is that they have a much lower magnification limit than other microscopes, such as the compound microscope, for instance. The stereomicroscope can magnify an image 100-150 times, while normal compound microscopes can magnify an image 1000-1500 times. This can be a disadvantage of stereomicroscopes, because not as much detail of the image is seen.
Answer:
b option is the correct answer
Answer:The mother's antibodies can destroy the red blood cells of the fetus.
Explanation:
If a woman with an Rh negative (Rh-) blood group has a child with an Rh positive (Rh +) male, there is a possibility that the child is also Rh +. Although this has no consequences throughout pregnancy itself, as the mother's and fetus's blood does not come into direct contact during pregnancy, it can have serious consequences for subsequent pregnancies.
In fact, rupture of the placenta at the time of childbirth may allow some red blood cells from the fetus to pass into the maternal circulation and cause sensitization, meaning the woman's body will detect them and begin to make anti-human antibodies. Rh that will persist indefinitely in the blood. If a woman regenerates another Rh + child, the anti-Rh antibodies present in her blood will pass easily into the fetus's blood through the placenta and attack and destroy the fetus' red blood cells, which can lead to severe fetal anemia and serious repercussions that sometimes lead to intrauterine death.
That statement is false

Answer:
a través de introducción antrópica
Explanation:
La introducción antrópica es decir, la acción del hombre (muchas veces de modo intencional), es la causa más común por la cual una especie exótica puede colonizar un nuevo ambiente. Generalmente, las especies exóticas compiten con especies autóctonas por la disponibilidad de recursos (alimento, hábitat, etc). Las especie invasoras que se adaptan a nuevos ambientes a menudo incrementan rapidamente su rango de distribución ya que el ecosistema no posee los mecanismos naturales para evitar su crecimiento poblacional (por ejemplo, presencia de depredadores adaptados para cazar la nueva especie). Como consecuencia de este proceso, una especie invasora puede convertirse en un serio riesgo para la biodiversidad y el equilibrio del ecosistema, causando muchas veces la extinción de especies autóctonas que son esenciales en la cadena trófica del ecosistema.
