为什么是这个答案
“As a result” shows cause and effect. “Nevertheless” and “in contrast” would signal an unexpected or opposite idea.
答案: B · The protein lacks one amino acid but the rest is unchanged

Because three bases are removed, the codons after the deletion are still read in the correct frame. The protein loses one amino acid, which may or may not affect its function.
答案
B · The protein lacks one amino acid but the rest is unchanged
16.护理入学考试生物
答案: D · It falls, because CO₂ forms carbonic acid in the blood
为什么是这个答案
CO₂ combines with water to form carbonic acid, which releases hydrogen ions. More CO₂ therefore lowers the pH and makes the blood more acidic (respiratory acidosis).
答案
D · It falls, because CO₂ forms carbonic acid in the blood
17.护理入学考试化学
答案: B · The temperature at which its vapour pressure equals 1 atmosphere
