Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.

Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way.

Which of these is correct regarding the permeability of a specific capillary type?

Red platelets are too vast to leave any capillaries. As capillaries are just a single cell thick and have thin porous dividers this implies substances can diffuse out of them effortlessly. Helpful substances, for example, oxygen and sustenance diffuse out of the blood in the vessels into the tissue liquid where it is then taken to the cells.

Que diferencias hay entre difusión simple y difusión facilitada
natima [27]

Answer: En la difusión facilitada, las moléculas solo se mueven con la ayuda de una proteína en la membrana. En difusión simple, las moléculas se mueven hacia abajo del gradiente de concentración, pero en la difusión facilitada las moléculas se mueven hacia arriba en el gradiente de concentración. La difusión simple es pasiva, pero la difusión facilitada es un proceso activo que utiliza energía.
