(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.

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
