CASOS EVOLUTIVOS: Dos especies de Drosophilas, que en la naturaleza tienen diferentes tiempos de reproducción pero cuando están juntas en un laboratorio se reproducen y pueden obtener descendencia fértil hasta la primera generación. ES URGENTE POR FAVOR

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers

to this one it would be receptive field
