As scientists, politicians, and concerned citizens recognize the threat of global warming to the ongoing climate change, reductions in greenhouse gas emissions become the forefront of the discussions. To reduce the presence and persistence of greenhouse gases in the atmosphere, their sources must be fully understood. Natural and anthropogenic sources for greenhouse gases can impact their presence in the atmosphere. Which of the options best matches the anthropogenic sources and the greenhouse gas accurately?

A) Methane- rice cultivation

CFCs- livestock farming

Carbon dioxide- landfill decomposition

B) Methane- corn and wheat agriculture

CFCs- fossil fuel combustion

Carbon dioxide- deforestation

C) Methane- fossil fuel combustion

CFCs- agricultural fertilizers

Carbon dioxide- volcanic activity

D) Methane- livestock farming and landfill decomposition

CFCs- refrigerants and propellants

Carbon dioxide- combustion of fossil fuels

the answer is D

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
