1. Write an editorial that urges homeowners to plant more trees on their
property.

Explanation:

Dear Editor:

Our country is facing a severe problem of air- pollution in every town and city. Scientifically speaking every adult is utilizing 250 mL of oxygen every minute, 15 L of oxygen every hour, and 360 L of oxygen every day. Similarly, every adult is expiring 200 ml of carbon dioxide every minute, 12 L every hour, and 288 L every day in the atmosphere.

Tree are the only source of oxygen and the only source to  clear carbon dioxide  from the atmosphere. Now a days trees are vanishing at a very fast speed due to urbanization and development. Every month our forest area is shrinking. There is an urgent need to plant more trees in order to save our nature and mother earth. This is a mandatory requirement for all of us to plant at least one tree and nurture it for the coming generation.

I have started this project from this year. I encourage my students, friends, and family members and relatives to plant and nurture at least one tree. Planting and nurturing a tree is a noble work. It gives satisfaction, mental peace, and a sense of well-being. I, humbly,request you to publish this message and oblige me.

and your question what topic are you in trouble with?

the krebs cycle and electron transport occur in the mitochondria, though other than that i would need to know more information.
