Plants and Animals

Behavior is Science. When I climb on the ladder to get a picture these baby Robins now open their mouths wide thinking Momma is here with food.

But when Momma and Daddy Robin notice I am there and start squawking the babies shut their mouths and flatten out so the supposed predator might not notice them.

Medicinal plants are science.

Foxglove is Digitalis purpurea and is the plant from which some cardiac glycosides such as digitoxin and digoxin are derived.

Roses that change color are Science. Mutabilis is a rose from prior to 1894 (about the same age as our house). It opens a peachy yellow, changes each day, first to a light pink and then to a dark pink. The change is caused by sunlight acting on the pigments. The fragrance changes daily too.
