D is your answer. It works faster than a lipid
<span>Lungs take in air, and diffuse (absorb) air into the capillaries of the blood. However, this process is two steps, one for inhalation and one for exhalation. Diffusion takes place in both processes, and serves different purposes. One is to absorb oxygen, the other is to rid co2.</span>
Answer:
muchos factores pueden contribuir a la variación de la población animal, incluidas las enfermedades, el suministro de alimentos, la sequía y la predicción natural. la sequía puede ser un factor de control importante y la mortalidad inducida por la sequía ocurrió en 1993 causando aproximadamente un 40% de mortalidad en la población de búfalos.

Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency
