Explanation:
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
The answer is muscle or the muscular system.
Muscular system is made up of muscle tissue that helps move the body and move materials through the body. In simpler explanation, muscle moves you. Muscles are bundles of cells and fibers that work in a simple way. They tighten up and relax. It consists of skeletal, smooth and cardiac muscles. <span />
There are various ways that geologists use for identification of minerals. These methods or tests are very simple to perform and can quickly help in the accurate identification of minerals. We will discuss here only three of them.
1) Hardness:
It is the property of a mineral that resists its scratching. It has something to do with the chemical bonding between atoms of a mineral. The stronger that bonding is, the difficult it is for you to scratch the mineral. Although presence of impurities can effect the right diagnosis of the mineral but still hardiness is a very good criteria to identify a mineral. For example, lead has very low hardness due to which we can write through it on paper, however a steal nib would never let us write because it has good hardness and it cannot be scratched easily. Please see the attached image, it shows hardness values of different minerals that give unique identification to them.
2)Streak:
It is the test in which mineral is scraped with a porcelain piece. This streaking can help in the diagnosis of the mineral in powdered form. For example, when chromite is streaked it gives choclate brown streaks and it is the color very different from all other minerals and it can be quickly identified.
3) Physical properties:
There are some ways of identifying a mineral by just looking at them, however some experts are better at it then some one who has zero experience. This is because minerals have some characteristics like color, luster (that can be metallic or non metallic) and taste or smell. For example, sulfur has a specific smell and it is quickly identified with it. Chalcanthite has a specific taste and it can be quickly identified with it.

There are choices for this question namely:
a) Release trapped air in the lungs
b) Strengthen the diaphragm
c) Prevent collapse of the airways
d) Condition the inspiratory muscles
<span>e) Control the rate and depth of respirations
</span>
There are multiple correct answers. The correct answers are:
(1) Release trapped air in the lungs
(2) Prevent collapse of the airways
(3) Control the rate and depth of respirations
The breathing technique that the nurse teaches the patient is called "pursed-lip breathing" wherein the patient inhales through the nose and exhales slowly through his puckered lips. This is done to release trapped air in the lungs (as COPD causes a ball valve like obstruction wherein there is difficulty exhaling rather than inhaling), prevent collapse of airways (therefore preventing an impending respiratory distress syndrome), and control the rate and depth of respirations (to prevent tachypnea or bradypnea that can result to respiratory alkalosis or acidosis respectively).
