You are doing research on nervous system diseases; particularly, one that dissolves lipids. what part of the neuron would you expect to be affected most by this disease?

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.

the fossil record provides evidence of a common ancestor to many species.

what is shown in the image?

eukaryote

chloroplast

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
