False. Pathogens can include a variety of organisms such as bacteria, viruses, fungi, and parasites that can cause disease in their hosts.
False. Disease transmission today is not necessarily as easy as it was in the past due to advancements in medical technology, sanitation practices, and public health measures. Remote groups and communities can also benefit from modern healthcare resources to prevent and control diseases.
False (A+)
The writer left out the statements regarding autoimmune disease. However, in autoimmune diseases, such as lupus, MS, or HIV, the white blood cells in the body are no longer able to protect the body against infection. The immune system has been compromised and a person has to be extremely careful and avoid getting sick. Also, the immune system starts attacking different organs in the body because they believe to be a threat. These are truths about autoimmune disease, anything saying different would be false.
True. Rh-negative mothers who are pregnant with Rh-positive babies can develop antibodies against the baby's blood, leading to hemolytic disease of the newborn in subsequent pregnancies.
Insufficient fluoride in water can lead to increased risk of tooth decay, but it does not typically cause discolored enamel. Discolored enamel is more commonly a result of factors like genetics, diet, or medication.
I believe it is correct (true), for England at least, but I'm not entirely sure...
False - "microbe" can be any microorganism, not just those that cause disease.
Fluoride is a natural element found in the earth's crust as well as in water and air. It's also considered a nutrient because our bodies need fluoride to grow and develop properly. Decades ago, scientists discovered that kids who naturally had more fluoride in their drinking water had fewer cavities. In the mid-1940s, communities started to put more fluoride in their water supplies to protect people against tooth decay. Fluoride helps because, when teeth are growing, it mixes with tooth enamel - that hard coating on your teeth. That prevents tooth decay, or cavities. But fluoride can help even after your teeth are formed. It works with saliva to protect tooth enamel from plaque and sugars. By using fluoride toothpaste, for instance, everyone can enjoy some cavity protection. Fewer cavities means healthier teeth when you're an adult - and less chance of having to wear false teeth (dentures) when you're old! So how do you get your fluoride? Ask your dentist the next time you have an appointment. In addition to fluoride toothpaste, he or she might recommend a mouthwash that has fluoride in it. And if your drinking water doesn't have fluoride in it, your dentist might suggest supplements - which are like vitamins containing fluoride. Just how effective is fluoridated water? Thanks to it, dentists say half of kids between 5 and 17 have never had a cavity in their permanent teeth.
False, Cigarette smoking does affect coronary heart disease.

No, most natural dietary fluoride comes from mineral deposits containing fluoride salts, this then leaches into drinking water. But with only a few rare exceptions this is rare. Most municipal water supplies have fluoride added and this would overwhelm any natural dietary fluoride sources.
No - the main goal of genetic engineering - is to eliminate weaknesses in the subject organism. Example 1 - Creating a strain of wheat that is resistant to disease False A+ls - Awesomeness399 :P

False
A false negative indicates that a person may not have a disease that is being checked for or that the person may not be pregnant. Having a false positive would be the opposite showing that the person does have a disease or could be pregnant.
No, it isn't a disease. To put it simply, a hypochondriac is a person who has a false belief that he or she has a disease or abnormal condition.
