Answer;

(3) the concentration of the substance is greater outside the cell than inside

Explanation;

-When a substance is of low molecular weight and has a higher concentration of the substance outside the cell as opposed to inside the cell then it is most likely to diffuse into a cell.

-Diffusion involves the movement of molecules from a region of high concentration to a region of low concentration, therefore if molecules are highly concentrated outside the cell then they are likely to move into the cell. Additionally, the size or the molecular weight of the molecules determines whether they will move into to the cell as the cell membrane only allows movement of materials in or out of the cell selectively.

Someone help me with this
nadya68 [22]
A horseshoe crab has been around for almost 500 million years. They are classified as arthropods and not actual crabs. However, There are many reasons that have helped them survive this long including, they can eat almost any organic matter. There blood is different from normal, in fact it’s blue. This blood helps them heal any wounds right away. They can also live in areas with very low levels of oxygen, meaning habitat is not a big issue for them. Evolution has also helped them grow and adapt seeing as they’ve survived this long.

Hope that helps:)

<h2>The correct answer is: Mutualism.</h2>

Explanation:

  • Mutualism can be defined as a type of symbiotic relationship.
  • Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
  • Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
