Question
Chapter 3, Problem 2AAE
Summary Introduction
To predict: The mRNA codon for the amino acid histidine with the triplet code in DNA
Introduction: mRNA formed by the transcription of DNA is translated to form the target protein. After splicing, mRNA is transported from the nucleus into the cytoplasm through the nuclear pores. In the cytoplasm, mRNA is bound to specific tRNA for the process of translation to continue.

6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in
relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in
diving humans.
• How might the location and slope of the O2 line differ for diving marine mammals such as
whales and dolphins?
•
How might the location and slope of the CO2 line differ for diving marine mammals such as
whales and dolphins?
•
•
Draw in predicted lines for O2 and CO2, based on your reasoning above.
How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line
differ for diving marine mammals?
What physiological mechanisms account for each of these differences, resulting in the ability
of marine mammals to stay submerged for long periods of time?

The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
