Maintaining a healthy lifestyle through diet and exercise is important, but it has no effect on the immune system. but it actually decreases the immune system. and it has been scientifically proven to boost the immune system. but it has not been proven to boost the immune system.

Answers

Answer:

D). But it has not been proven to boost the immune system.

Explanation:

As per the question, maintaining a healthy lifestyle through diet and exercise is significant however it has not been proven to boost the immune system. A healthy lifestyle including a balanced diet along with regular exercise corresponds to enhancing immunity and contracts the risk of diseases yet no specific proof has been scientifically approved that a healthy lifestyle(including exercise and healthy diet) nurtures the immune system. Thus, option D is the correct answer.

Final answer:

A healthy diet and regular exercise positively impact the immune system while stress can have negative effects. Temporary stress may not significantly affect a healthy person's immunity, but prolonged stress or conditions like immunosuppression can weaken the immune response.

Explanation:

Eating a healthy diet and exercising regularly does boost your immune system. Research has shown that these lifestyle choices have a positive effect on the immune system, which fights off pathogens and prevents us from falling sick. It is also important to note that being sedentary or having an unhealthy diet can weaken the immune system, making us more susceptible to infections or ailments.

Stress can negatively impact the immune system as well. The human body reacts to stress by releasing cortisol which can suppress the immune system when present in large amounts over a prolonged period. This makes us more susceptible to infections. However, short-term stress may not impair the immune system in healthy individuals to a degree that leads to a higher incidence of diseases.

It is also noted that the immune system can sometimes fail or breakdown, a state referred to as immunosuppression. In such cases, the body becomes more vulnerable to infections and diseases, with the extreme case being HIV/AIDS, where the immune system is completely destroyed by the virus.

PLEASE HELP!!! I NEED HELP QUICKLY!!!!`In his 2011 State of the Union Address, President Barack Obama said:
"To attract new businesses to our shores, we need the fastest, most reliable ways to move people, goods, and information—from high-speed rail to high-speed Internet. Our infrastructure used to be the best, but our lead has slipped. The jobs created by the transcontinental railroad & the Interstate Highway System didn't just come from laying down track or pavement. They came from businesses that opened near a town's new train station or the new off-ramp.

We've begun rebuilding for the 21st century. And tonight, I'm proposing that we redouble those efforts. We'll put more Americans to work repairing crumbling roads and bridges. Within 25 years, our goal is to give 80% of Americans access to high-speed rail. Within the next five years, we'll make it possible for businesses to deploy the next generation of high-speed wireless coverage to 98% of all Americans. This isn't just about faster Internet or fewer dropped calls. It's about connecting every part of America to the digital age."

Analyze the types of appeal used in President Obama's statement. Use your findings and examples from the text to explain whether this is an argument or persuasion. Answer in a minimum of three complete sentences.
