Any substance that triggers an immune response

Answers

Answer 1
Answer: A substance that triggers an immune response is called an antigen. Antigens are any factors that can induce an immune response, thus the release of antibodies in the body. Examples of antigen include bacteria, toxins and foreign blood cells. 
Answer 2
Answer:

Final answer:

An antigen is any substance that triggers an immune response. This can include foreign macromolecules, or even harmless substances that the body identifies as foreign. Unnecessary immune responses to harmless antigens can lead to allergies or autoimmune diseases.

Explanation:

Any substance that triggers an immune response is known as an antigen. Antigens are usually foreign macromolecules that are recognized by the cells of the immune system. However, an individual's immune system may also identify harmless substances as antigens, leading to an immune response, such as in the case of allergies or autoimmunity.

In the case of allergies, an individual's immune system reacts to a harmless protein or substance, like pollen, thereby causing symptoms like sneezing or itchy, watery eyes. This is due to an overactive immune response, known as a hypersensitivity response, resulting in the synthesis of IgE antibodies that mediate the allergic reaction.

Autoimmune responses, on the other hand, occur when an individual's immune system mistakenly attacks the body's own cells, causing diseases like rheumatoid arthritis or systemic lupus erythematosus. These arise from a breakdown in tolerance, a process that usually suppresses immune responses to harmless macromolecules.

During physical activity of moderate intensity, your heart will beat at a percentage of its maximum rate. What is the target heart rate for moderate-intensity activity?

Answers

The target heart rate for moderate-intensity activity is between 64% and 76%1,2 of your maximum heart rate.

How to estimate the maximum heart rate?

Estimate our maximumheart rate based on our age. To estimate your maximum age-related heart rate, subtract your age from 220.

  • Generally, to figure out whether you are exercising within the target heart rate zone, you must briefly stop exercising to take your pulse. You can take your pulse at your neck, wrist, or chest.
  • We recommend the wrist. You can feel the radial pulse on the artery of the wrist in line with the thumb. Place the tips of the index and middle fingers over the artery and press lightly.
  • Do not use the thumb. Take a full 60-second count of the heartbeats, or take for 30 seconds and multiply by 2.
  • Start the count on a beat, which is counted as “zero.” For example, if this number falls between 109 and 129 bpm in the case of a 50-year-old person, he or she is active within the target range for moderate-intensity activity.

Hi there! I believe the answer would be GENETICS, as that is the only answer that cant possibly be avoided! Drugs, smoking and sex are all learned habits and can be avoided with proper caution! But genetics are determined at birth, and cannot be changed, no matter how hard you try!

A study is being performed to assess the effectiveness of a new medication to relieve pain from arthritis. Researchers recruit 300 subjects suffering from arthritis. They randomly assign half of the subjects to receive the new medication, and half to receive a placebo. After one hour, they record whether or not each patient is experiencing pain relief. The results are given in the table below.
