Answer:
The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.
The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.
During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.
In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.

Would a plant be able to survive if the ground tissue was damaged? Explain your answer.
Given what we know, we can confirm that with damaged ground tissue, a plant will most likely not be able to survive.
What we know about ground tissues in plants.The ground tissue forms an abundant part of all plant tissues. This tissue includes all plant tissue that is neither vascular nor dermal.This means that ground tissue covers a wide variety of functions. Two primary and important functions are the storage of sugar and water.Therefore, given the vital role of this tissue in plants and its function in storing "food" and water, we can confidently say that a plant with damaged ground tissue will not be able to survive for long.

Explanation:
cytochrome c is a protein found in all species, and functions in energy metabolism. the more closely related two different species are,
The more closely related two different species are, the more alike their cytochrome C amino acid sequences are. The cytochrome C is an evolutionarily conserved protein.
The cytochrome C is an evolutionarily conserved protein involved in cellular respiration.
The cytochrome C is a carrier of electrons that acts during the oxidative phosphorylation stage of cellular respiration.
This protein is evolutionarily conserved in species whose cells generate ATP in anaerobic (oxygen presence) conditions, which means that generally synonymous mutations are observed when comparing the amino acids of this protein.

The mitochondria
The Krebs cycle or citric acid processes in the mitochondrial matrix yield a substance called NADH. Adenosine triphosphate is then produced from NADH by enzymes included into the mitochondrial inner membrane (ATP).
What is the main role of mitochondria in nutrient energy?Organelles, or “tiny organs,” are what mitochondria are. They generate ATP (adenosine triphosphate), a chemical that is used by the cell to power the various tasks it must perform, as a source of energy.
The creation of cellular ATP by oxidative phosphorylation is undoubtedly one of the activities of mitochondria, but they also play significant roles in ion homeostasis.
Various metabolic pathways, apoptosis and programmed cell death, as well as the production and consumption of ROS.
Therefore, mitochondria transform nutrient material into an energy form that is used by the cell.
