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.
Answer:
Calcium
Explanation:
Between Neon and Calcium, neon will be more stable compared to the calcium.
Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.
- Calcium on the other hand is reactive
- It requires a loss of two electrons to attain stability.
- Therefore, it is a more reactive element.
Answer:
Hydrogen ion(H+)
Explanation
The human blood has carbonic acid and bicarbonate anion as buffer to maintain the blood pH between 7.35 and 7.45. A virtual value higher than 7.8 and 6.8 can lead to death.
Taking coffee which has a low pH will lower the pH of the blood. In order to raise the pH back to normal and lower the level of acid present in the system. The human buffering system will to take up Hydrogen ion.
