Alveoli are the part of the human respiratory system where actual oxygen exchange takes place.

 

Alveoli<span> are tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream. Learn more about how they function and quiz your knowledge at the end.</span>

 

The correct answer between all the choices given is the last choice or letter D. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

You have studied some microbes that cause disease. Understanding how microbes grow and multiply is important when identifying an
Mila [183]

Answer:

Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm

Function: metabolic functions are carried out in the bacterial cytoplasm

Replication: generally asexual (binary fission)

Explanation:

Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles . Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, <em>Salmonella</em> is a genus of infectious bacteria that may cause an outbreak. <em>Salmonella</em> infection may be prevented by eliminating conditions where they can multiply. Measures to prevent <em>Salmonella</em> outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.

BabaBlast [244]

Answer:

The statement that will show the best accurate criteria is patient's respiratory rate is 16 breaths/minute and blood pressure is 130/72 mm Hg.

Explanation:

Adrenergic drugs are drugs that cause the stimulation of the sympathetic nervous system, which is also known as adrenergic nervous system by performing or mimicking the activities of the epinephrine and norepinephrine, or interfering with their release.

It should be noted that, epinephrine and norepinephrine are also known as adrenaline and noradrenaline, this is because they are secreted by the adrenal gland, and this gives rise to the term adrenergic.

Examples of adrenergic drugs are phenylephrine, clonidine and oxymetazolin among others.
