Answer:
Paralysis is usually caused due to damage in the nervous system, particularly spinal cord.In majority of cases, people get paralysis due to any kind of accident or medical condition which affects functioning of the muscles and nerves. So, if there is any kind of injury to the spinal cord or a stroke, paralysis occurs
Answer:
The correct option is B. Activation energy
Explanation:
The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.
For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.
The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
An ideal gas is one in which the gas molecules do not
interact with each other, hence intermolecular forces of attraction is
negligible. For this to occur, the pressure must be low and temperature is high
so that the volume or space between molecules is very large. This can be taken
from the ideal gas equation:
PV = nRT
where an increase in temperature and decrease in pressure
makes the volume increase
<span>So a noble gas other than radon which would depart most
readily from ideal gas behaviour must have also a high density. From the
tables, this would be Xenon.</span>
Both the Amy and Rosalie are correct.

What is Circulatory system?</h3>
The heart, blood vessels, and blood itself circulate throughout the entire body of a human or other vertebrate through the blood circulatory system.
The blood contains of the red and white blood cells along with plasma and other substitutes of blood.
Also the blood has the function to supply the nutrients to the cells of the body along with transporting carbon dioxide to the alveoli of the lungs.
The circulatory system is a closed pack system with the involvement of various organs like the heart the lungs and plays a crucial role in maintaining the homeostasis of the body.
