Answer:
Combustión
Explanation:
La combustión es el proceso mediante el cual la materia reacciona con el oxígeno y se convierte en dióxido de carbono y agua.
Otro nombre para la combustión es quema. Cuando el metano se quema en el aire, se convierte en dióxido de carbono y se devuelve a la atmósfera según la reacción;
CH4 (g) + 2O2 (g) -----> CO2 (g) + 2H2O (g)
Answer:
Allopatric speciation occurs due to the geographical isolation between individuals of the same species. The geographical isolation can be due to canyon development, mountain formation, migration, etc.
The geographical isolation gives different environmental condition to the separated population of same species to live which allow these two population to evolve differently and evolve in different species.
So when two population becomes different species and not able to interbreed with each other when give opportunity then the allopatric speciation between the two populations becomes complete.
"A. Natural resources and human labour".
I agree.
The right answer is D.
The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.
This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.
External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.
Hey there,
Your correct answer to this question would be of that "<span>A statement of fact that is generally accepted to be true and universal because it has always been observed to be true."

Hope this helps you.
