Which is an example of active transport? a
Cells move sugar into their cells with energy
Water moves from where there is more water to where there is less
b
с
Salt moves from a 15% solution to a 2% solution
d
Dye moves from where it is dropped throughout an entire glass of water

с ) Salt moves from a 15% solution to a 2% solution

Explanation:

In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient.Aug 14, 2020

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
