The cells directly responsible for cellular immunity are the cytotoxic T cells (lymphocytes).

    Cellular immunity is an immune response against infectious diseases caused by viruses and some bacteria. This mechanism does not involve antibodies, but rather cytotoxic T-lymphocytes, phagocytes and the release of cytokines in response to an antigen. <span>Cytotoxic T cells, perform their function by killing infected cells via apoptosis.</span>

sleet_krkn [62]

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway.

<h3>Further explanation </h3>

Examine the accompanying wind rose diagram. Based on the information shown, determine the correct answers to the following questions.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the color coding and think carefully about the best position for each label when multiple locations seem possible.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway. This relationship explains why planes circle above an airport so they can land in the correct orientation, and why they reorient themselves after taking off in a direction other than the direction they wish to fly. In our example, the longest spoke in the wind rose diagram indicates prevailing winds are coming from the NE and blowing toward the SW. Therefore, the correct orientation for the runway is along this path, with planes taking off in the SW to NE direction. This wind pattern can be found where NE trade winds are located.
