(Ch. 27.4) Many people are allergic to substances in the environment, such as ragweed pollen, as well as foods, such as peanuts. Which of these statements BEST describes an allergic reaction to one of these substances? (1 point) A. The substance is similar or identical to human antigens, and so it triggers an immune system response. B. The substance invades the body and causes damage to tissues, which triggers an immune system response. C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response. D. The substance invades the body and triggers a response from the respiratory system or digestive system, but not the immune system.
Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.

...here is the question...
Why are fermenting bacteria used to protect foods from rot?
Answer:
The desirable bacteria cause less deterioration of the food by inhibiting the growth of the spoiling types o bacteria. Some fermenting processes lower the pH of foods preventing harmful microorganisms to live with too acidic an environment. Controlled fermentation processes encourage the growth of good bacteria which starves, or fights off, the bad microbes. Depending on what is fermented, or the manner of fermentation, foods can remain consumable for years!!

1) How can you still justify saying that Canada has a population density of 8.7 people
per square mile when in the city of Montreal alone there is a population density of
approximately 2, 192 people per square mile?
Answer:
Due to average population density.
Explanation:
The population density of Canada is the average population density of the whole Canada whereas the population density of city of Montreal refers to the population density of one city only. There are some regions in the country usually in the rural areas where population density is very low while on the other hand, the population density of cities are very high due to more job opportunities so that's why the population density of Canada is lower as compared to the city of Montreal.
Scientists predict that ocean acidity could double (increase 100%) by 2100. What are the effects of ocean acidification on ocean plant and animal life give (2 examples) and on humans (give 2 examples)?
Thank you!
Answer:
Reduce amount of carbonate and dissolve calcium carbonate.
Explanation:
Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. ... Animals that produce calcium carbonate structures have to spend extra energy either repairing their damaged shells or thickening them to survive.
Ocean acidification will affect humans too! It will affect the food we eat since most of our shellfish requires calcium carbonate to form or to fortify their shells. Many of the fish we eat are also dependent on shelled animals for their food source, so the entire food chain is in jeopardy

Answer:
1) Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Answer:
In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.
In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.
