Answer:
Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.
Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.
Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.
Thus, a person becomes immunised.
Regular water temperature has a high surface tension. Without surface tension, small particles like dust could sink into the water and kill marine life that live below. This could cause whole ecosystems to be destroyed. I hope this helps!
Artificial sweeteners help reduce the amount of sugar in the diet with obvious benefits for general health. It can also make a big difference in your dental health by helping you prevent tooth decay.
True The second law of thermodynamics is broken when a fertilised egg grows into a sophisticated adult organism. The second law of thermodynamics is broken when a fertilised egg grows into a sophisticated adult organism.
<h3>What does chemistry's second law of thermodynamics say?</h3>
According to the second rule of thermodynamics, processes and chemical reactions only take place if and only if they cause an increase in entropy in the universe that is higher than or equal to zero.
<h3>Do cells fall under the second rule of thermodynamics?</h3>
No Closed systems fall under the purest application of the Second Law of Thermodynamics. Closed systems cannot exist in living systems; otherwise, they are not living.
