Answer: Young children
Explanation: Resistance to food borne illnesses develops through exposure to small amounts of food borne pathogens. The longer the exposure, the greater the buildup of immunity. Young children are more likely to succumb to food borne illnesses due to lack of exposure to pathogens, and resultant lack of resistance to them.
<h2>Answer:</h2>

Answer:Explanation: Viruses are acellular organisms and although they do not have cells, they are extremely dependent on these structures, since they do not have their own metabolism and do not have any organelles. Viruses can only reproduce within a host cell other than fungi and bacteria
Explanation:
Stem cell therapies are not new. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued.
The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. Political leaders began to debate over how to regulate and fund research involving human embryonic stem (hES) cells.
Newer breakthroughs may bring this debate to an end. In 2006 scientists learned how to stimulate a patient's own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.
