Answer:
Once you begin CPR, do not stop except in one of these situations:
You see an obvious sign of life, such as breathing.
An AED is available and ready to use.Another trained responder or EMS personnel take over.You are too exhausted to continue. The scene becomes unsafe. If at any time you notice that the person is breathing, stop CPR. Keep his or her airway open and continue to monitor the person’s breathing and for any changes in the person’s condition until EMS personnel take over.
Explanation:
Answer: A) Photosynthesis
Photosynthesis:<em> </em><em><u>The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water</u></em><em>. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.</em>
Cellular Respiration:<em> </em><u><em>Is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate</em></u><em> (ATP), and then release waste products.</em>
Decomposition:<em> Is the process by which organic substances are</em><u><em> broken down into simpler organic matter</em></u><em>. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death.</em>
Burning Fossil Fuels:<em> </em><u><em>is a fuel formed by natural processes,</em></u><em> such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years.</em>
(<em>Extra</em>)>Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of <em>photosynthesis</em>, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.

"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.
