Why do the walls of the alveoli need to be thin? What is the physical mechanism of the transport of oxygen and carbondioxide? Explain how the structure of the gastrointestinal tract is related to it's functions. Explain how you describe the journey of blood through the heart and lungs, sta...
Explain the Krebs Cycle. Respiration: Respiration is the energy-releasing process in all living cells in which complex biomolecules are broken down to release energy, which is captured in the molecule ATP. Respiration can either occur anaerobically (without oxygen) or aerobically (with oxygen), wher...
The carbon and hydrogen combine with oxygen from the air to make carbon dioxide gas and water, while the energy that held the molecules together is released as heat. This process, which is called combustion, releases huge amounts of energy. When you sit round a camp fire, warming yourself ...
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms.
OTEC can also be used to produce fuels such as hydrogen; the electricity it generates can be used to power an electrolysis plant that would split seawater into hydrogen and oxygen, which could be bottled or piped ashore and then used to power such things as fuel cells in electric cars. ...
Briefly explain the following: Effects of increasing nitrogen and carbon dioxide on the environment. How does atmospheric nitrogen become the same nitrogen in plants? What is the role of nitrogen in eutrophication? Describe the nitrogen cycle and its correlation with fertilizers. ...
Describe the functions of blood. Describe how to do a hematocrit test. What are the average hematocrit values for males and females? What makes red blood cells different from other body cells? Explain in detail how oxygen and carbon dioxide are transported in the blood. Be sure to include th...
They have an important role in the defense of the organism with their antimicrobial activity through the generation of reactive oxygen species (ROS), the activation of protease, and the establishment of neutrophil extracellular traps (NET). In addition to the production of TGF-beta, metalloprotease...
they're sometimes calledheat engines. The process of burning fuel involves a chemical reaction calledcombustionwhere the fuel burns in oxygen in the air to make carbon dioxide and steam. (Generally, engines makeair pollutionas well because the fuel isn't always 100 percent pure and doesn't bur...
