Answer:
Pollution is the presence of harmful materials in the environment of a substance that has harmful or poisonous effects. Nitrogen dioxide (NO2) and Carbon monoxide (CO) are 2 pollutants of air and Industrial Waste and Sewage and Wastewater are 2 pollutants of water.
During inhalation, you breathe in and this contracts the diaphragm and moves downwards. This increments the chest cavity space which means the lungs are expanding. The intercostal muscles or the muscles in between the ribs also aids in the enlargement of the chest cavity. Both muscles contract to pull your rib cage upward and outward when you inhale. As your lungs expand, air is sucked through your nose and mouth. It then travels down to the windpipe and into the lungs to the bronchus, bronchioles and eventually in the alveoli where air exchange between carbon dioxide and oxygen happens.
The additional accessory muscles of respiration are typically used only under conditions that are of high metabolic demand or respiratory dysfunction. However, in instances where these muscles become stiff and hard, expansion of the rib cage can be quite restricted. The accessory muscles of respiration include sternocleidomastoid and the scalene muscles namely anterior, middle and posterior scalene. Both aid in elevating the rib cage. However, their involvement seems to depend on the degree of respiratory effort. During quiet breathing, the scalenes are consistently active at certain phases while the sternocleidomastoid is quite.

Answer:
The two factors that increase the size of a population are natality, which is the number of individuals that are added to the population over a period of time due to reproduction, and immigration, which is the migration of an individual into a place.
Explanation:
For fluid resuscitation in hemorrhagic shock, about 3 ML of crystalloid for every 1 ML blood lost. 3 L of fluid needs to administered to raise the intramuscular volume by 1L.
Fluid administration should continue until the patient's hydrodynamics become stabilized. Crystaloids quickly leak from vascular space, fluid expands the blood volume by 20-30% . Lactated ringer's solution is used balanced salt solution for fluid resuscitation in hemorrhagic shock.
Colloid solution are generally not used. Those who have dehydration and adequate circulatory volume typically free water deficit and hypo-tonic solutions.Lost blood volume with intravenous fluids called crystalliods. Consistency of liquid is thin and saline solution.
