Answer:

1.The immune system is a complex network of cells and proteins that defends the body against infection. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognize and destroy the microbe quickly if it enters the body again.

2. Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek phagein, "to eat" or "devour", and "-cyte", the suffix in biology denoting "cell", from the Greek kutos, "hollow vessel".

3. Lymphocytes are primarily involved in the body's immune response mechanism. This involves complex phenomena which end in the development of humoral and cellular immunity. Humoral immunity involves the production of antibodies (immunoglobulins), and is brought about by lymphocytes, which are called B-cells.

4. 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.

5.Flu viruses continually change over time. This constant changing enables the virus to evade the immune system, so that people are susceptible to the flu throughout life.

Hope this helped! ^^

How can you reduce your risk from ETS?
Nana76 [90]

One can reduce the risk of Environmental tobacco smoke(ETS) by visiting places that are smoke-free.

Environmental tobacco smoke (ETS), or second-hand smoke, is the air polluted by tobacco smoke.

ETS consists of mainstream smoke (smoke exhaled from the smoker's lungs) and side stream smoke (smoke from the lit end of a cigarette, pipe, or cigar).

Conventional smoke exhaled by the smoker has a lower concentration of carcinogens, nicotine and tar. For this reason, side-stream smoke is more dangerous than mainstream smoke. ETS from tobacco, cigars, and pipes contain over 4,000 chemical compounds.

Over 50 of these chemicals are carcinogens. Several studies have shown that infants exposed to ETS are more likely to develop asthma than their unexposed peers. Inhaling ETS poses a serious health hazard.

Health Risks for Non-smokers

Second-hand smoke kills about 3,000 people each year from lung cancer. ETS causes eye irritation, headaches, ear infections, and coughing in people of all ages. It aggravates asthma and other respiratory disorders and increases the risk of coronary artery disease.

Achondroplasia is a type of dwarfism in which the long bones stop growing during childhood, resulting in limbs that are dispropo
kvv77 [185]

Answer:

The best answer to the question: Which zones do you think would be most affected by this disorder, would be, C: Proliferation and hypertrophic zones.

Explanation:

The reason why a human being is able to grow from his/her small body when borh, to his/her adult body size is in part because his/her bones continue developing and growing, meaning enlarging, until they reach their adult, and fully matured size. However, in people with Achondroplasia this is not the case. Essentially, people with this affection will have problems at the zones of the bone where both proliferation of the chondrocytes and hypertrophy of the tissue that has been produced takes place. This will cause for an incomplete enlargement and formation of the fully-grown and development of the bone, and which becomes evident in people with this affectation due to their limbs being more "child-like" than in adults who did not suffer from it.
