As there are no options to choose from I can only answer this based on statistics and averages. So on average a family will spend around 20% of their income on food to feed their family. It does of course depend on what the income level of the family is but that is the rough estimate for a typical family.
"What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
<em>How do Rosa's body systems work together to get the molecules she needs into her cells?</em>
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).
How do hair cells use these molecules to release energy for her body to run?
The substrates (glucose and oxygen) enters the bloodstream and then taken up to the cell. Then they are provided to the mitochondria for the release of energy in the form of ATP. This is why mitochondria are known as the powerhouse of the cells. Within the cell, energy is released in a three-step process, i.e. glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. In the end, aerobic respiration per reaction run produces 36 molecules of ATP which are sufficient to meet intensive energy needs. During exercise, the supply of oxygen and glucose is also faster due to faster lungs and heart actions.

So you have enough energy to do things for tomorrow.
To allow your body to rest after the things you did during the day.
The answer to this question is positive reinforcement.
There are two types of reinforcements: positive and negative. While the definition of positive reinforcement is given in the question, negative reinforcement occurs <u>when the behavior increases because an aversive stimulus is removed. </u> Reinforcements are the basic concepts that govern the principles of <em>operant conditioning</em>, which was researched by Skinner.
When the impulse reaches the end of the axon, chemicals are released and picked up by a neighboring neuron, causing the nerve impulse to continue. ... Your emotions, decisions, and physical actions all happen through nerve impulses traveling through neurons in your brain, spinal cord and nerves.
