Here, the red color is unable to express itself in the heterozygous condition and produce pink color.

First, I chose to put a Chipotle container into the trash, instead of the recycling. This wasn’t the best decision, because it could have gone to the recycling and helped others.

Secondly, my family owns a compost bin and compost machine that helps compost vegetable waste, fruit scraps, coffee grounds, and other compostable items. Choosing to do this helps the environment in many ways.

Thirdly, I picked up many aluminum cans on the side of the road to crush and collect. After several months of collecting them in a container, my family and I bring them to a place that recycles and reuses metals and aluminum.
