An extra chromosome is known as a trisomy and one less chromosome is known as a monosomy. Why are these good words for a disorder with extra or missing chromosomes (look at the root words)?​

prefix meaning for "mono" means "one and "tri" means three

These are good words for a disorder missing a chromosome (mono) or having an extra (tri) since it is litterally telling you it either has 3 or 1 chromosome

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)

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.
