Answer:The raw materials required for the process of photosynthesis are carbon dioxide, water and solar energy.
The carbon dioxide present in the atmosphere diffuses into the leaf through stomata.

Solar energy is obtained from the sun which gets trapped by the chlorophyll pigment present in the leaves.
Explanation:
Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).
The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine (fight-or-flight hormones).
* It accelerates the metabolism and is activated for example in case of danger or fear, to prepare the individual to escape.
* It affects the cardiovascular system: it increases the heart rate and induces peripheral vasoconstriction, causing an increase in blood pressure.
* At the digestive level, it slows the muscular contractions of the intestines but promotes the release of glucose by the liver.
* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.
We need options :) but stem cells are a amazing type of cells that are able to develop into many different types of cells <span>First, they are unspecialized cells capable of renewing themselves through </span>cell division<span>, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.</span>
