Answer:

The correct answer is case-control study.

Explanation:

In a case-control study, two groups of the population are used, in which one group is kept as control, and the other is known as the experimental group that encounters with a specific disease or an outcome. With the help of this study, one can expose the groups to various or single outcomes.  

In the given case, a study is done in which an advertisement on a ban on smoking is encouraged by the non-smokers at the alcohol sale points but not by smokers, in the process a random digit dialing method was used. This random digit dialing method is an illustration of a case-control study, in which the survey of the individuals is done regarding the ban on smoking.

Why do astronauts eat freeze dried food I space
zmey [24]
Food was cooked, quickly frozen, and then dehydrated in a special vacuum chamber. Freeze-dried food didn't need to be refrigerated and would last a long time. To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water.

Vines climb using tendrils. Specialized plant structures respond when they "touch" something like a wall or trellis. The tendril
alexgriva [62]
This is called <span>thigmotropism

It comes from ancient Greek and basically means to touch in a certain direction. They don't, however, only react to touch; they react to things like wind too in order to latch and not be separated when there's wind blowing on them. </span>

What is the relationship between gaps and fossils?To find fossil evidence to fill the largest remaining gap in whale evolution,
Over [174]

Answer:

To find the fossil evidence to fill the largest remaining gap in whale evolution, you would search age sediment of 37MYA-46MYA.

Explanation:

Fossils are the dead remains of living organisms. The gaps between the fossils usually point out the uncertainties in the understanding of precisely how species are evolved. However, the gaps do not indicate the weakness in the theory of evolution itself. There are many gaps in the fossil records that continue to shrink with time as new fossils are discovered. The gaps are contingent features of fossil records.

Secondly, to discover the fossil evidence to fill the largest remaining gap in the evolution of whale, you would search the age sediment of 37MYA-46MYA.

What is the primary reason that a hot spring will kill a fishplaced
Leto [7]

Answer: E.) The high temperatures denature (destroy) most of the

fish's enzymes, but the bacteria have enzymes adapted to

these temperatures.

Answer:

Explanation:

Extreme temperature can damage the enzymes and they will no longer remain active. This can causes the denaturation of enzymes. Certain species of bacteria are thermophiles, that is bacterial species can live in the environment, which exhibit temperature higher than normal.

The fish enzymes may not be able to sustain in the high temperature and the fish will die but if the bacteria belong to the thermophile strain then the bacteria will hey adapted to the high temperatures of hot spring.
