Cytokines are those molecules that are used for cell signaling, or cell-to-cell communication
Cytokines can be used to communicate with neighboring or distant cells about initiating an immune response
Cytokines are also used to trigger cell trafficking, or movement, to a specific area of the body
The innate immune system is made of defenses against infection that can be activated immediately once a pathogen attacks
Mast cells are found in mucous membranes and connective tissues, and are important for wound healing and defense against pathogens via the inflammatory response
When mast cells are activated, they release cytokines and granules that contain chemical molecules to create an inflammatory cascade
The cytokines released during this process act as a messenger service, alerting other immune cells to make their way to the area of infection or to be on alert for circulating threats
<em>A team of astronomers discovers a new planet with water. They notice that the process of evaporation does not seem to be working on this planet. Which statement best explains the state of the water cycle on this newly discovered planet?</em>
<em></em>
<em>The water is trapped as water vapor in the atmosphere and clouds.</em>
Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.
