Answer:
The Cardiovascular System
Explanation:
The respiratory system draws air into the lungs. Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream. The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart. As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.
This is called passive immunity. Passive in such a way that the vaccine came from another human blood plasma which contains antibodies that temporarily combats disease-causing virus/bacteria. Vaccination with gamma globulin transiently boosts patient's immunity against illnesses or diseases.
Answer:
introns will remain inside the bacteria
Explanation:
Introns are the remains of an RNA transcript that do not involve in coding and hence they are trimmed off once the protein is translated from the RNA molecule.
Introns are found more commonly in eukaryotic genomes as compared to bacterial and archaeal genes
Group I introns have an ability to invade tRNA, rRNA and protein through its intervening sequences however their insertion into genes is phenotypically neutral.
