To test the effectiveness of an allergy drug, scientists begin with a pool of 12,000 allergy sufferers. one randomly selected group of 6,000 subjects is given the drug, and the other 6,000 are given a pill without the active ingredient. they are asked to report their allergy symptoms after 1 week, 1 month, and 3 months of treatment, and samples are also taken to measure the levels of histamines (allergy-related compounds) in the blood. what group is receiving the experimental treatment in this study?

6000 with the drug with the active ingredient being tested.

Explanation:

The group that was given the drug with the active ingredient is the group that is receiving the experimental treatment which  is 6 000 with the factor being tested.

all freedom fighters demanded for constitution. so british finally granted india it's freedom. then a constituent assembly was formed. it's chair man was rajendra prasad and its deputy chairman was dr. br ambedkar.

this assembly take the time of about one year than our constitution was finally formed.

explanation:

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
