Answer:
The protein would be incorrect and the protein might not function.
Explanation:
We know that introns carry information but introns not only carry information to build a protein. They have to be removed for the mRNA to encode a protein with the right protein sequence.
If the spliceosome fails to remove an intron, an mRNA with extra "junk" will be created in it. As a result, a wrong protein will be created during translation.
If a wrong protein sequence is created, it will hamper the whole translation process. The protein won't function properly.
Answer: Alveoli
Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.
