Answer:
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.
Information
The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.
Your body's cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.

Answers:
1. Three problems associated with alcohol
a. High blood pressure
b. Liver and kidney disease or cancer
c. Heart diseases
2. “The direct answer to this question is that the government does not decide the legal status of drugs based on scientific assessment of potential for harm.
The ranking of drugs is a very interesting and controversial topic (subject to the apples and oranges problem), but it is simply not the basis by which governments make these decisions. The chart is worth analyzing, but it won't answer the question.
Practically speaking, making alcohol illegal is untenable. It was attempted in the United states in the 1920s, and I am not aware of any credible historians that consider prohibition to have been a success. Alcohol use has been present amongst humankind for millennia. It spans society, race, social class, etc. It does certainly present great potential for harm, individually through the detrimental health effects of abuse, and societally through the impact of impaired decision making, most notably drunk driving.
Despite that, alcohol also clearly provides some benefits that drive some people to use it. Others choose not to use it at all. Many use it without issue, and some develop problems. It is an effective social lubricant. In many cultures it is a common component of traditional celebrations, and in some cultures it is even a component of formal business interactions. It is one of the central rituals in the Catholic church.
Many of the problems associated with alcohol use can be reasonably mitigated without blanket prohibition, i.e. drunk driving and age restrictions. Many of the problems are also solved through basic social structures, in which friends and family address issues independently.
Given the above, the clear follow-on question is why these other, less harmful, drugs are illegal? If alcohol has demonstrated that it is actually more effective to manage these problems with regulation, how are other legalization decisions being made?
Those are much more complicated questions. The brief answers have to do with legacy (less history of widespread human use with other chemicals) and institutional racism.”

<span>True. Hunger just like any other emotion in the
body is a chemical reaction that occurs within the brain. This signals the body that it<span> is
in need of nutrients essential for many organ system functions. There are many
chemical processes within the body that need essential nutrients (eg.
carbohydrates, fats) to perform efficiently. Without food, the body will be
weak and there will be complications within the internal organs. Hunger is a
natural behavior of all living organisms and is essential for survival and
overall a major cause of evolution.</span></span>
