anabolic reactions are where
products of digestion are digested into the blood stream and used to make larger molecules
metabolism is
the sum of all chemical reactions taking place in an organism

does water have adhesive properties
yes
water’s adhesive properties make it a good… because…
transport medium, they create a pull on the water column, which plants use to transport water from roots to leaves
