Answer:
The correct answer is - to allow air and blood to escape.
Explanation:
An occlusive dressing is a dressing that involves water and airtight on the wound or the opening in first aid. It is used to protect the incision or wound to be contaminated.
In the case of the pneumothorax development, the occlusive dressing is sealed with the three-sided but the fourth side is left open so it will allow air to the escape from the pleural space and blood with the prevention of the backflow of air with inspiration.
Thus, the correct answer is - to allow air and blood to escape.
Answer:
Answer=2
Explanation:
Chi square test is a statistical test commonly used to compare observed data with data we would expect to obtain according to a specific hypothesis
Chi square formula
=∑(observed value-expected value)/(expected value)2
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:
Plant cells, in other words: <em><u>Plants</u></em>
Explanation:
In plant cells, the vacuoles are much larger than in animal cells.
Stay safe and Merry Christmas! :)
If ice did not float, the world would be a hot mess. Ice reflects lots of sunlight, so if it was at the bottom, our world would be significantly hotter. Additionally, plants grow at the bottom, so if they were trapped in ice, the water would run out of oxygen and everything would die. Bottom feeders would not exist, because they would be frozen. Also, the ice would just like on, because the water above prevents it from melting entirely, leading to all of our bodies of water eventually freezing.
