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.
Osmoreceptors within the hypothalamus detect and increase in plasma osmolarity. This results in a decrease in ADH release from the posterior pituitary, and hence decrease in water permeability of the collecting duct.
<h3>What is osmoregulation?</h3>
Osmoregulation is that the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to take care of the homeostasis of the organism's water content; that is, it maintains the fluid balance and therefore the concentration of electrolytes to keep the body fluids from becoming too diluted or concentrated.
The tendency of water to move into one solution from another by osmosis is osmotic pressure. The upper the osmotic pressure of a solution, the more water tends to maneuver into it.
<h3>Osmoregulation through kidney :</h3>
Pressure must be exerted on the hypertonic side of a selectively permeable membrane to stop diffusion of water by osmosis from the side containing pure water. Although there could also be hourly and daily variations in osmotic balance, an animal is usually in an osmotic steady state over the long term.
Organisms in aquatic and terrestrial environments must maintain the proper concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic.

Answer:
<em><u>Boy </u></em>code
Explanation:
The Boy Code is <em>a collection of generally non-verbal rules and boundaries that tend to characterize boyhood and masculinity in America, according to William Pollack, PhD, author of Real Boys.</em>
The Boy Code's four foundational pillars are:
- <em>The Sturdy Oak </em>- Men and Boys must not be frail. No weeping, whimpering or hurt gestures allowed.
- <em>Give ‘Em Hell</em> - Boys are considered to be extremely active risk-takers who are physically violent. Boys often learn quickly that most of their poor behavior will be brushed off as "boys will be boys."
- <em>The Big Wheel</em> - Rank and superiority are vital; it's important to try to get to the top of the rankings, regardless of the cost. There's no embarrassment.
- <em>No Sissy Stuff</em> - Feelings are the women's domain, according to the Law. Especially feelings of tenderness.
Answer:
Interrupted time series
Explanation:
According to Wikipedia, Interrupted time series analysis, sometimes known as quasi-experimental time series analysis, is an approach for the analysis of a single time series of data known or conjectured to be affected by interventions (controlled external influences).It refer to the specific point at which the intervention was implemented and allow researchers to examine the effect of an intervention where multiple observations are obtained prior to the intervention to establish a baseline.
