Final answer:

The components of a wellness model for long term weight management include physical activity, nutrition, and mental behavior. Each is important for maintaining healthy weight in the long term. The body's response to perceived starvation, helpful to our ancestors, can hinder weight loss today by conserving energy and increasing fat storage.

Explanation:

The six components of a Wellness Model for long term healthy weight management include: physical activity, nutrition, stress management, sleep, interpersonal relationships, and mental behavior. Three of these are physical activity, nutrition, and mental behavior.

Physical activity is an important component of long-term weight management because it helps burn calories, build muscle, and maintain a healthy metabolism. Regular exercise has benefits beyond weight management, including reducing the risk of chronic diseases and improving mental health.

Another component, Nutrition, involves having a balanced diet which incorporates all essential nutrients needed by the body for good health and weight management. This includes fruit, vegetables, whole grains, protein, and healthy fats.

Mental behavior refers to the psychological aspects of weight management. This involves maintaining a positive self-image, forming healthy habits, and managing stress effectively. A healthy mindset is crucial for long-term weight loss and maintenance.

As to the body's response at the cellular level to perceived starvation threats, when a person is dieting or ill, the body can go into what is often referred to as 'starvation mode'. This is where the body slows down the metabolic rate, preserving energy, and increasing fat stores for future use. This was an immensely helpful adaptation for our early ancestors who faced frequent periods of food scarcity. Nowadays, it can hinder weight loss progress because when we diet, our body clings to fat stores, making it harder to lose weight.

Which statement correctly describes the inflammatory response process? A. blood vessels dilate, swelling occurs, phagocytes ingest foreign bacteria or viruses B. phagocytes enter the area, swelling occurs, enzymes are released to ingest foreign bacteria and viruses C. acids are released, enzymes are released, phagocytes enter the area and ingest foreign bacteria and viruses D. cells are destroyed and bacteria or viruses are ingested, blood vessels dilate, swelling occurs

Answers

B is the closest answer. When an immune response is triggered, phagocytes are induced and they go to the site of the invasion by the foreign body. These then digest and destroy the bacteria that triggered the response. Other cells are also activated at this point to assist with the immune response.

blood vessels dilate, swelling occurs, phagocytes ingest foreign bacteria or viruses
