Q2.18. Which of the following techniques is least likely to improve your ability to detect a trend in a climate data set?

○ Decreasing the length of the data set by using data just from recent years

○ Focusing on regional averages instead of local observations

○ Analyzing temperature anomalies instead of absolute values

○Using more accurate instruments and techniques to collect data

 

Q2.19. Climatologists look for climate change in many components of the climate system. Which of the following statements has the least direct evidence?

○ Global mean surface temperature has increased since 1850 .

○ Arctic sea ice, glaciers, and ice sheets have decreased in size over the past 50 years.

○ The length of the growing season in the U.S. has decreased since the 1890 s.

○Global mean sea level has risen significantly since 1880 .

I need answers to these 2 questions please. Thanks

1) About 20% of the carbon dioxide that is produced in the tissues (from burning fuel) is transported on the hemoglobin molecule.

A. How is carbon dioxide transported on hemoglobin?

B. How many carbon dioxide molecules can bind to each hemoglobin molecule?

C. How does the other 80% of carbon dioxide move from the tissue in the lungs?

2) During hyperventilation too much carbon dioxide leaves the lungs. What effect will this have on the function of hemoglobin? Will the hemoglobin deliver more or less oxygen to the tissues? Explain your answer.

I need answers to these questions very urgently.

1-identify the possible consequences of prescence metal ions in cotton bleaching baths using your knowledge of chemistry

2-provide a simple model for representing the mechanism causing this problem using your knowledge of chemistry

3-choose convenient application method and sequestering agents to solve the problem

4-evaluate the success posibility of your solution by comparing the method and chemical chosen with other possible alternatives taking into consideration their solubilities, complex stabilities, complex forming abilities ecological effects (including biodegradability)
