Answer:
The answer is Pulmonary alveoli
Explanation:
Pulmonary alveoli are the primary gas exchange site. The alveoli are in intimate contact with the surrounding capillaries, removing the CO2 from the blood and passing the oxygen through a pressure gradient. This barrier between air and blood has a thickness of approximately one micron. To maintain this exchange gradient to the lungs, between 5 and 8 L of air per minute must enter.
Answer:
False
Explanation:
Meta-analysis does not have to be necessarily included in a systematic review.
The main characteristic of a systematic review is that it analyzes a question using explicit and systematic methods that will help to select and analyze data from studies. The use of statistical methods, which are also known, as meta-analysis is optional, but it can help during the analysis.

scientists doctors and dentists.
Answer:a. The concentration of salt in a person's urine increases after that person eats a large bag of salty chips.
Explanation:
Homeostasis is the quality of the body to maintain the normal state of the body with respect to changes occurring in the external environment.
The homeostasis is maintained by involving the negative feedback loops. These loops function in opposite to the stimulus, that triggers them. For example, if the body temperature is high, the negative feedback loop will function to bring the body temperature down towards the set point, or the target value.
The homeostasis can regulate the ion concentration. When the body acquires salt by eating chips, the urge to expel salt through urine also increases. Hence, the ionic concentration of salt is maintained through negative feedback loops altering homeostasis.
