Which came first elevators or skyscrapers?

The answer must include that before skyscrapers, men built what at the time were considered "very tall" buildings between 4 and 10 floors high. They put elevators into these smaller "very tall" buildings. When skyscrapers came later, the concept of elevators simply went along with the concept of extremely tall buildings that tried to reach the sky. So, technically, elevators came before skyscrapers, in numerous small and large towns with what was then "very tall" buildings that were only a fraction of the size of skyscrapers.


What is the probability of producing a tall pea plant from genetic cross between two hybrid tall pea plants?

Assuming the gene/allele for a tall plant is dominant and short is recessive this is an impossibility. As in order for both parent plants to be short both chromosomes must contain the t (allele for short) and so the T (allele for tall) cannot be present and will not be passed on to the offspring and it cannot be tall.


What are the advantages of induced draught cooling tower over forced draught cooling tower?

When a project is originally designed, the designer must decide whether a natural draft or mechanical draft tower offers the best economic result. Mechanical draft towers are substantially less costly to purchase, but have the disadvantage of having a continuous auxiliary power draw. They are also physically smaller and shorter. Natural draft towers consume no auxiliary power, but are very expensive to purchase and erect. They are very large and tall. Often times, plants do not have enough "real estate" to fit such a large structure. One must do an economic analysis to establish which option is the best choice, economically. They are also simpler, not having any moving parts


Why was the petrona's twin towers built?

Like all skyscrapers, a vanity project. In the good old days, a big pyramid was a symbol of your importance, and later on a cathedral filled the desire. With the arrival of technology, came bridges and hydro dams, and atomic power plants are a current equivalent. Tall towers are a modern phase.
