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.

The Difference is during aerobic respiration, carbon dioxide, water, and ATP are produced meanwhile, during anaerobic respiration, lactic acid, ethanol, and ATP are produced.

Answer:
The process that produces mRNA is known as transcription.
Explanation: Transcription is the first process that occurs during protein synthesis when part of the DNA.
Answer: Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). ... One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.
