<span>b. t cells and memory cells
</span>
These immune cells produce a proper response chemical to combat the microbes. The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination.  However some cells of the immune system called lymphocytes remain with a memory of that pathogen.<span>As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it . </span>

Why does the Department of Homeland Security target foot-and-mouth disease?
Zinaida [17]

The bottom- and- mouth complaint contagion has been honored since at least the 16th century.

  • It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.

  • Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.

  • The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.

  • FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint. With one in nine Americans employed in the husbandry or confederated diligence, the goods of an FMD outbreak in the U.S. would be ruinous ­ – estimated at nearly$ 200 billion in lost profit over 10 times across affected diligence.

Therefore the Department of Homeland Security target foot-and-mouth disease.

What is a major difference between facilitated diffusion and active transport?
xenn [34]

Answer:

The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>

Explanation:

Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.

Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
