1 answer:
Vanyuwa [196]3 years ago

Answer:

Urea is a <u>nitrogenous</u> substance​

Explanation:

Urea is a substance that is formed in the body during the processing of proteins and nitrogen compounds in the liver, and that we generally excrete through urine and sweat. If it is not eliminated properly, the levels of urea in the blood rise above normal (uremia) and this causes health problems that especially affect the liver - the organ responsible for processing proteins - and the kidneys (which must filter the final waste product), and that without treatment can become serious, and even cause the death of the patient.

List and explain four new methods or inventions in agriculture in this era.
ipn [44]

Answer:

1. Cotton Gin: In colonial times, cotton cloth was more expensive than linen or wool because of the extreme difficulty of separating seed from the clinging fibers. One man could pick the seeds from only about 1 pound of cotton fiber per day.

2. Reaper/Binder: Small grains had been harvested by hand for centuries, cut with sickles or scythes, hand-raked and tied into sheaves. Grain harvesting machines first appeared in Great Britain in about 1800, and in the U.S. a decade or two later, but most failed. Obed Hussey and Cyrus McCormick developed successful reapers during the 1830s. 

3. Thresher: When grain was being cut by hand, the method for separating the kernels from the straw was equally slow and labor intensive. Grain was hauled to a barn where it was spread on a threshing floor and either beaten with hand flails or trampled by animals. That knocked the kernels free of the straw, which was then raked away. The remaining mixture was winnowed by tossing it into the air where the wind was relied upon to blow the chaff and lighter debris away from the heavier grain, which fell back onto the threshing floor.

4. Combined Harvester-Thresher: By the 1920s the steam traction engine was on it's way out, but it paved the way for the gasoline tractors that followed.

Ronch [10]

Tammy interprets her fieldwork data after reading Susan Crawford Sullivan's research, which explains that low-income religious women often don't go to church both because of logistics and because of stigma. Because of this, their religion is still important as a source of resilience and meaning. Sullivan argues that both organized and personal religion can provide important resources to poor urban mothers facing difficult challenges.

In recent years there have been reports of restaurant employees spitting into food they serve to get even with customers they do
ludmilkaskok [199]

Answer:

Yes. Such an action constitutes a tort and a crime.

Explanation:

A tort is a wrong done to another person while a crime is the breaking of the law of the state or Federal  government. Put simply, a tort is a wrongdoing on a personal level while a crime is a wrongdoing on a societal level, while tort is privately morally wrong, crime is publicly legally wrong.

In the scenario above there is a 'tort' because the employees are spitting into the food of those they do not like. This is on a personal level as they are not spitting into the food of every customer but only the food of those they dislike. Also, a crime exists because this is happening at a public place. It can be said that those restaurants are intentionally serving unhealthy foods to members of the public and both the owners and employees of those restaurants could be charged.
