Scientists detect their effect on the matter nearby, say if a normal star passes near a black hole, the black hole will pull it towards itself tearing it apart, as the attracted matter accelerates it emits x-rays that radiate in space till it reaches the Earth.

FinnZ [79.3K]

Answer:

Nuestro planeta esta habitada por numerosas <em>especies</em>, muchas de ellas extendidas en grandes y diversas zonas. Sin embargo, existen especies que habitan una sola <em>área/región</em> con características<em> ambientales</em> únicas para su desarrollo.

Explanation:  

Entre las miles de especies que habitan el planeta, muchas de ellas pueden estar ampliamente distribuidas, mostrando adaptaciones a una gran variedad de ambientes y hábitats, mientras que muchas otras solo se encuentran restringidas a determinadas areas o regiones particulares que presentan condiciones ambientales determinadas. Esta diferencia en distribución esta muy relacionada a la historia de la especie,  a la edad de la misma sobre la tierra, adaptaciones a los ambientes y capacidades reproductivas y de dispersión.

Dentro de la clasificación de especies de acuerdo a su distribución, podemos mencionar a las especies

  • nativas: aquellas que habitan y se distribuyen las áreas naturales donde se originaron,
  • endemicas: entran dentro del concepto de nativas, pero a parte se caracterizan por habitar <u><em>unicamente</em></u><em> una región en particular debido a las condiciones ambientales</em> que les son propicias para su desarrollo. Estas especies no pueden trasladarse a otras regiones.
  • exoticas: aquellas especies que salen de su area natural de distribución para habitar otras areas mas lejanas. Allí pueden establecerse e interactuar con especies nativas sin causar grandes daños.
  • invasoras: especies exoticas que llegan a otras areas, que se establecen y que tienen la capacidad de reproducirse a una tasa superior a la de las especies nativas, invadiendolas y desplazandolas. Interactuan con las especies nativas y causan daños importantes.

Los términos nativos, endemicos, exóticos son <em>relativos al área a la que se esté haciendo alusión</em>: un continente, un país, una región o un bioma.

Tomtit [17]
Antibodies, also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it.<span>
