Sedaia [141]

The amount of water reabsorbed during the formation of urine can be changed by hormones, enabling the creation of either concentrated or diluted urine. The duct serves this purpose.

In heating, ventilation, and air conditioning (HVAC), air is delivered and removed by ducts, which are conduits or passageways. Examples of the necessary airflows include supply air, return air, and exhaust air.  As part of the supply air, ducts frequently deliver ventilation air as well. As a result, air ducts are one way to guarantee both thermal comfort and adequate interior air quality. The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated. The body makes less pee when its ADH level is high. A low

Zepler [3.9K]

Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.

<h3>What is meant by Pathogen?</h3>
  • A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
  • Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
  • The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
  • Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.

Therefore the correct option is D)  can activate cells of the adaptive immune system.

Give one example of how the testing of Platismatia glauca could benefit future ecological research of this forest.
storchak [24]

Answer:

Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

hope this helps:)
