The correct answer is :The completion of the construction of the Panama Canal took place six months early because new machines and technologies were invented.

The preparations lasted three years and the construction of the canal began in 1907. It was a very large company. The workers began their journey at 7 in the morning and rested on Sundays. At dusk they were transported by trains to their homes. In the morning, crews of workers drilled the rock to introduce dynamite. At lunchtime, the workers rested and the dynamiters began their turn. In the afternoon, crews equipped with mechanical shovels loaded the debris into the wagons. At 5 o'clock in the afternoon most of the workers stopped working, but drilling and explosions continued.
The Americans decided to build two sets of gates: one to raise the boats up to the level of Gatun Lake - about 26 m above sea level, at the exit of the canal to the Caribbean - and another to lower them at the opposite end of the canal. These gigantic gates, built on the ground, required 3.4 million cubic meters of concrete. Its base had a thickness of 4 to 6 m and the walls, perforated like a hive to empty or fill the gates, measured almost 15 m thick at the base.
The Panama Canal cost the US government 352 million dollars - four times more than the Suez Canal - and claimed 5,609 lives, including accidents and illnesses. Even so, the cost was 23 million dollars less than budgeted and the channel was inaugurated six months earlier than expected, in August 1914.
Answer:
1. True
Proteins are frequently called the building blocks of life because they are found everywhere: in our cells, bones, muscles, blood, hormones, enzymes and more. It is thanks to proteins that our body has any sort of structure to it.
2.False
Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.
3. False
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
4. False
False, blood cells don't have a rigid cell wall. Plants and Bacteria have rigid cell walls, but not blood cells!
