Answer:

Option 2, Arousal

Explanation:

Reticular activating system (RAS) or the  ascending arousal system consists of nuclei and tracts and is involved in the regulation of wakefulness, sleep aspects and arousal.  

RAS is located in the mesopons and interacts with the basal forebrainand thalamocortical systems.  It activates the cerebral cortex and thereby maintain the consiusness. The neurons located at the pontomesencephalic junctionparticipates in this activity of arousal.  

Hence, option 2 is correct

the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
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.

What criteria would you use to assess the reproductive success of a plant?
alexira [117]
Reproductive success is defined as the passing of genes onto the next generation in a way that they too can pass on those genes. This is not solely the number of offspring produced by an individual, but also, as Ronald Fisher outlined in 1915, the probable reproductive success of those offspring, making mate choice (a form of sexual selection) an important factor in this success,[1] making biological fitness a key element in the theories of natural selection and evolution.
