GEOGRAPHY
Greece is^ made^ up^ of^ the^ lower^ part^ of^ the
Balkan peninsula,^ which^ is^ in^ the^ northeastern
part of^ the^ Mediterranean^ Sea.^ It^ has^ numerous
islands off^ the^ coast.^ Greece^ is^ bounded^ on^ the
east (^) by the^ Aegean^ Sea,^ and^ on^ the^ west^ by
the Adriatic^ Sea.^ On^ the^ north^ are^ other^ Balkan
countries. Greece^ has^ many^ fine^ harbors^ and
much natural^ beauty.^ However,^ the^ mountain
ranges and^ the^ deep^ valleys^ cut^ Greece^ into^ iso
lated sections.^ Generally,^ the^ soil^ is^ stony^ and
dry, although^ there^ are^ some^ valleys^ that^ havve rich, red^ earth.^ Usually,^ little^ rain^ falls^ except along the^ eastern^ border.

Over six^ hundred^ of^ these^ striated^ muscles are in our^ body. All^ of^ them^ are^ voluntary^ muscles and need^ to^ be^ directed^ by^ our^ brain^ to work. Most of^ the^ meat^ eaten^ by^ human^ beings^ is

Smooth muscles^ are^ the^ type^
