Roots derive nutrition from the soil. When living things die and decay, minerals and nutrients are added to the soil from decomposition. These nutrients are absorbed from the soil through the root hairs. Hope that helps. Have a nice day.
Lysosomes and chloroplasts are unique to plant cells.
Answer:
The original water sample contains 830,000 cells per milliliter.
Explanation:
A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.
The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).
Answer:
The second code in this case is the procedure for perfusion
Explanation:
Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
