Yes, an increase in physical activity can lead to an increase in your basal metabolic rate (BMR) because it can boost your muscle mass and overall calorie expenditure. Regular exercise can help to raise your BMR over time, which can contribute to weight loss and improved overall health.

Factors that can increase BMR are food and decrease it is the lack of food. You're welcome for the answer :D
Higher temperatures can lead to an increase in basal metabolic rate (BMR) as the body works harder to regulate its temperature through processes like sweating. Conversely, colder temperatures can also raise BMR as the body expends more energy to maintain warmth. Overall, extreme temperatures can impact BMR by requiring the body to work harder to maintain homeostasis.
The Basal Metabolic Rate (BMR) for a 14-year-old boy who weighs 120 lbs can vary, but a rough estimate would be around 1400-1600 calories per day. BMR can be influenced by factors such as muscle mass, body composition, and activity level. It's always best to consult with a healthcare provider for personalized advice.
When measuring Basal Metabolic Rate (BMR), it's important to ensure the individual is in a fasting state, both physically and mentally at rest, and has not engaged in any strenuous physical activity prior to the measurement. Additionally, the environment should be thermoneutral to prevent any external factors from influencing the metabolic rate measurement.
Endothermic organisms have a higher Basal Metabolic Rate (BMR) because they rely on internal heat production to maintain their body temperature. This requires more energy expenditure compared to ectothermic organisms, which rely on external sources of heat to regulate their body temperature. Additionally, endothermic organisms have higher metabolic demands due to their higher activity levels.
