Claim-Evidence- Reasoning (CER) Question: Are humans made of stardust?

Biology
1 answer:
miss Akunina [59]3 years ago
5 0
For decades, science popularizers have said humans are made of stardust, and now, a new survey of 150,000 stars shows just how true the old cliché is: Humans and their galaxy have about 97 percent of the same kind of atoms, and the elements of life appear to be more prevalent toward the galaxy's center, the research found.

The crucial elements for life on Earth, often called the building blocks of life, can be abbreviated as CHNOPS: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. For the first time, astronomers have cataloged the abundance of these elements in a huge sample of stars.

Which of the following is not an essential role of the liver? Which of the following is not an essential role of the liver? prot
True [87]

Answer: urea disposal

Explanation:

<u>The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage. </u>

The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.

The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. <u>Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine. </u>

So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.
