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.

Explanation:
The correct option is BY CONDUCTING EXPERIMENTS THAT EXPOSE THEIR PROPERTIES.
Scientific investigations are always ongoing in all parts of the world, scientists strive to build on existing knowledge by carrying out more experiments that are targeted at obtaining more information above that which is already known.
1. The correct answer is 4. Carbon can bond to 4 other atoms, exponentially increasing its ability to make different molecules.
2. The correct answer is 3. An organic compound (or molecule) is any atom (usually hydrogen) that bonds with carbon.
3. The correct answer is the third option (8 electrons). Valence electrons in the outer shell are those can form a chemical bond. When (most) atoms have 8 electrons in their outer shell, they are then considered to have maximum stability.
4. The correct answer is 2. These macromolecules all contain carbon and hydrogen, making them organic compounds.
Research the Pancreas, it's functions are not at all talked about enough. Perhaps give me a brainliest answer?
