Answer:
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
Explanation:
Answer:
The correct answer is B. Prokaryotic cell consumed a smaller cell.
Explanation:
Endosymbiosis theory says that the origin of eukaryotic cell happens when a bigger prokaryotic cell consumer a smaller prokaryotic cell but the bigger cell did not consume the smaller cell rather these two cells remain in symbiotic association with each and later evolved as a eukaryotic cell.
The evidence of this theory can be seen in eukaryotic cells in the form of mitochondria and chloroplast in animal and plant cells. These two organelles are very closely related to today's prokaryotic cells.
Both the organelles have their own circular genome enclosed in double membranous structure and 70s ribosomes which resembles the bacterial cell. Therefore, the correct answer is B. Prokaryotic cell consumed a smaller cell.
Answer:
The adaptive immune response is divided into two branches. The first is immunity, in which antibodies are produced that bind to the foreign cell. In the second branch, immunity, recognizes foreign cell structures and can destroy or help activate infected cells, which can generate plasma cells that produce specific antibodies.
Explanation:
Specific antibodies are those proteins that mark certain pathogens, these are manufactured by cells of the immune lineage, and the acquired defense, that is, the one acquired by humans during their growth, is not born with these antibodies.
Specific antibodies are formed once a pathogen has been recognized, that is, in the second encounter between the pathogen and the organism, that is why we are talking about a first infection and a second infection.
These antibodies are recognized as those that are formed in some vaccines.
