Answer:
Both photosynthesis and cellular respiration occur in plants. However, the rate of photosynthesis exceeds that of cellular respiration during the day when there is sunlight. The Chlorophyll pigment picks up energy from the photons and uses it to reduce carbon dioxide into carbohydrates. During the night, when there is little sunlight, the rate of photosynthesis drops down below that of cellular respiration, that breaks down these energy molecules made in photosynthesis to supply the plant’s cellular processes with energy.
Answer: The hormones are stored in the Endocrine System and secreted in the blood.
Explanation: The Hormones are ductless, they do not have ducts. So the hormones are secreted in the blood. The endocrine system has glands which produces one or more hormones. Thus the hormones are stored in the Endocrine System.

Answer:
As the heart pumps, glucose is carried in the bloodstream to cells all over the animal’s body. Oxygen which enters the animal’s body through its respiratory system (lungs, gills, skin, or exoskeleton) is carried by its transport system (blood for many animals to every animal cell. Once the glucose and oxygen arrive in the cell they can go through a chemical reaction. Glucose reacts with oxygen to produce carbon dioxide and water. Cells transform the chemical energy in the glucose molecules into energy for cell functions, motion energy, and heat. Because of cellular respiration, muscle cells have access to the energy necessary to contract or relax in response to a signal from the brain sent through nerve cells, so muscles can contract or relax enabling the animal to move. During cellular respiration, energy is released in the cell to enable the work of the cell to occur. The atoms found in glucose are rearranged into carbon dioxide and water and are no longer needed by the cell so they are considered waste products. Cells have to get rid of unwanted waste products. Carbon dioxide and water move out of cells and into the blood. The blood carries the carbon dioxide and water to different places in different animals (the lungs, gills, skin, kidneys, or exoskeleton) where they are released into the environment. Animal movement we observe at the macroscopic scale is possible because cellular respiration is happening at the atomic-molecular scale.
An action potential is the variation of the electrical potential associated with the passage of a pulse along the membrane of a muscle cell or a nerve cell.
<h3>What is a nerve cell?</h3>
The nerve cells are the cells involved in the formation of nervous tissue. it helps in the conduction of stimuli through the nervous system.
An action potential is the variation of the electrical potential associated with the passage of a pulse along the membrane of a muscle cell or a nerve cell.
Thus, the answer is action potential.
