During exercise, blood CO2 levels increase as a result of muscle cell activity. This makes blood more acidic, which disrupts pH homeostasis. Drag the following events in the regulation of gas exchange into the proper order.
Answers
I will put the events in order and further explain what happens to gaseous exchange during exercise.
During exercise,
- Blood CO2 increases,
- Blood becomes more acidic-PH decreases below the set point,
- Brain stem detects PH change,
- Brain cell signals muscles in the diaphragm and rib cage,
- Breathing level increases,
- Amount of CO2 exhaled increases,
- Blood PH returns to the set point.
During exercise,the cells of the muscles respite more than when the body is at rest.Heart rate increases abd,more oxygen is used or required and more CO2 is exhaled.
The rate and depth of breathing increases and this is in a bid for the body to compensate by making sore that more oxygen is absorbed into the blood as well as remove more carbondioxide
When CO2 combines with water, carbonic acid is formed,this makes the blood to become acidic.
Therefore,when CO2 is present in the blood,it decreases the blood PH and an excess of it (PH less than 7.35) will result in Acidosis.
Your colleague asks you to verify her findings about a new polymer intended for use as a vascular graft. It must be reasonably elastic; otherwise, the blood will be constricted and increase its flowrate downstream with each pulse of the heart. She found that the material was sufficiently elastic for use inside the body. After running a tension test, you find that it is too brittle for use. Your colleague reviews your protocol and declares that you have either graduated from Duke or checked your eyelids for light leaks during Dr. Brudno's BME 203 class, because it definitely is adequate. Describe two mistakes you may have made. Put a (1) and (2) before each of your reasons.
Answers
Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.

The process represented in the diagram is photosynthesis because Photosynthesis is the process whereby green plants makes use of water and Carbon dioxide from the atmosphere in the presence of light to produce its food and also producing oxygen as its by product in the process
Photosynthesis :
H₂0 + CO₂ + light energy -----> C₆H₁₂O₆ + O₂
Hence we can conclude that the process in the image is Water, carbon dioxide and light are inputs while oxygen and glucose are outputs

Why do fats have higher caloric value than other organic molecules?
Answers
Fats have higher calorific value. Fats have high energy than other molecules.
What is high calorific value?Calorific value, which is measured by measuring the heat generated by the full combustion of a particular quantity of a substance, is nothing more than the energy present in a fuel or food. Currently, this is typically given as joules per kilogram.
A device called a calorimeter is used to calculate calorific value. In order to determine how much heat was generated during combustion, a predetermined amount of the object being investigated is burned under carefully controlled conditions.
Therefore, Fats have higher calorific value. Fats have high energy than other molecules.
