A single piece of coiled DNA is called a plasmid.
Answer:
Viruses and Bacteria
Explanation:
Bacteria are single-celled, prokaryotic microorganisms that exist in abundance in both living hosts and in all areas of the planet. By their nature, they can be either "good" or "bad" for the health of plants, humans, and other animals that come into contact with them. A virus is acellular (has no cell structure) and requires a living host to survive; it causes illness in its host, which causes an immune response. Bacteria are alive, while scientists are not yet sure if viruses are living or nonliving; in general, they are considered to be nonliving.
Infections caused by harmful bacteria can almost always be cured with antibiotics. While some viruses can be vaccinated against, most, such as HIV and the viruses which cause the common cold, are incurable, even if their symptoms can be treated, meaning the living host must have a strong enough immune system to survive the infection.
-Lung volume is the total volume the air occupies in lung during respiration. It is also known as lung capacity. -Air pressure is the pressure of the air in the lungs during inhalation and exhalation. During the process of inhalation, the lung volume expands because of the contraction of the diaphragm and intercostal muscles, thus expanding the thoracic cavity. Because of the increase in lung volume, the air pressure is decreased (Boyle’s law) compared to the atmosphere, thus the air enters the airways. During exhalation, the relaxation of the diaphragm and intercostal muscles causes a decrease in the lung volume, resulting in increased air pressure in the lungs compared to the atmosphere, thus the air moves out of the airways.
Answer:
Explanation:
There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.
