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.
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
Probability is the greater or lesser possibility of a certain event occurring.
In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:
total number of possible cases= 48 + 30 + 67= 145
The number of favorable cases for a moth to be brown is: 48
Then the probability that a moth is brown is calculated as:
= 0.33= 33%
On the other side, the number of favorable cases for a moth to be yellow is: 30
Then the probability that a moth is yellow is calculated as:
= 0.21= 21%
In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
