Answer:
Explanation:
Una estrella de unas 38 veces la masa del Sol y otra ligeramente inferior, de unas 32 masas solares, están tan cerca que comparten una única envoltura. Ambas orbitan alrededor de un centro de masas común, y acabarán fusionándose en una única estrella supermasiva, dicen los científicos, de unas 70 veces la masa del Sol. “Será dentro de algunos millones de años, ni siquiera decenas de millones de años, y tenga en cuenta que eso no es apenas nada en términos astronómicos… nuestro Sol tiene 4.500 millones de años de vida”, explica a EL PAÍS Javier Lorenzo, astrónomo de la Universidad de Alicante y líder del equipo que ha descubierto y caracterizado está sistema binario. MY Camelopardalis, situado, en la constelación de la Jirafa, está a una distancia de entre 12.000 y 15.000 años luz de la Tierra, en nuestra galaxia.
The answer is all of the above because they are all true.
So the answer is D
Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.

Answer:
The thermosphere is very high above the Earth and is distinguished by an increase in temperature with altitude. The density of the air is extremely low, but the activity of the molecules are very high due to the amount of energy they are receiving from the sun. Individual molecules can be as warm as 2000 degrees C.
