Since Lillian consumes 2100 kcal of foods and beverages and expends a total of 1800 kcal, then her body is in a state of positive energy balance.
<h3>What is a state of positive balance?</h3>
The expression 'state of positive energy balance' indicates a difference between the calories consumed and burned.
This state of positive energy balance is due to higher consumption of calories regarding calories burned each day.
In conclusion, since Lillian consumes 2100 kcal and expends a total of 1800 kcal, then her body is in a state of positive energy balance.

Pulmonary embolism occurring in up to 3 in every 1,000 births is a major cause of death.
One of the pulmonary arteries in your lungs can get blocked, causing a pulmonary embolism. The majority of the time, blood clots from deep leg veins or, rarely, veins in other parts of the body that go to the lungs cause pulmonary embolism (deep vein thrombosis).
Pulmonary embolism, which occurs when blood clots obstruct the flow of blood to the lungs, can be fatal. But the danger of dying is significantly decreased with quick treatment. By taking precautions to avoid leg blood clots, you can lessen your risk of developing pulmonary embolism.

Answer:
because the sodium channels have a refractory period following activation, during which they cannot open again and it ensures that the action potential is propagated in a specific direction along the axon.
Answer with Explanation:
Homeostasis<u> allows an organism to regulate its internal condition in order to adapt to a changing environment.</u> In order to maintain this, the positive and negative feedback mechanisms (loops) remain essential <em>when it comes to physiological processes that are deemed complicated.</em>
<em>Let's talk about the "Negative Feedback Loop."</em>
- The "baroreceptors" are sensors in the blood vessels.
- For example, when the body's temperature changes, the body's initial reaction is to return to its normal level. So, it goes the same way with blood pressure. When the baroreceptors sense an increase or a decrease in blood pressure, it communicates with the hypothalamus by sending a signal. Then, the hypothalamus sends a message to the organs that are responsible for returning the blood pressure to normal level. These organs are the heart, kidneys and blood vessels. So, if a person experiences a "dropping blood pressure," heart stimulation follows (causing an increase heart rate) due to hormonal vessel constriction. This also allows the kidney to retain more water, thereby increasing the blood pressure.
This is how all these elements work together to achieve homeostasis.
