Nitrogen released from the breakdown of proteins is used in the synthesis of urea, which is excreted by the kidneys in the urine.

  • The urea acid cycle transforms the nitrogen waste released during this process into urea, which is then excreted in the urine.
  • Amino acids can be converted into energy during famine and go via the Krebs cycle.
  • Muscle protein is broken down into amino acids while fasting, some of which are partially oxidized to provide energy.
  • These amino acids are split up into alanine and glutamine, which are released into the circulation together with other amino acids.
  • Several tissues, notably the stomach and kidney, oxidize glutamine, converting some of its carbons and nitrogen to alanine.
  • The liver is where alanine and other amino acids are processed into glucose and ketone bodies and nitrogen.

Multiply 5730 years by 2 since two half-lives have gone by for carbon.

<u>Explanation</u>:

The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years  

The half-life of carbon-14 is 5730 years.  

In this manner, after  

1 half-life there is 50 % = 1/2 of the first amount left.  

2 half-lives there is 25 % = 1/4 of the first amount left.  

25% is two half-lives.  

Every 50% of life requires 5730 years.  

So two half-lives require 2 × 5730

Transcription begins at a promoter. What is a promoter? a. A site in DNA that recruits the RNA Polymeraseb. Part of the RNA mole
arsen [322]

The correct answer is: a. A site in DNA that recruits the RNA Polymerase

Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.

N76 [4]
 that the chromatid pairs become visible
<span>
Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>

Which characteristics do mars and earth share? check all that apply.
Delvig [45]

Atmosphere, and active volcanoes, such characteristics is shared by mars and earth.

<h3>How do both mars and earth share characterstics?</h3>
  • Both the planets have the same area of dry land. This is because two-thirds of the area of Earth's surface is covered with oceans but water is absent on Mars.
  • Both Mars and Earth exhibit temperature and atmosphere.
  • The geological processes on Mars and Earth are common for example formation of volcanoes, canyons and impact basins.
  • Mars exhibits rings but the earth does not.
  • Earth exhibit distinct seasons but Mars do not due to reducing and hot atmospheric condition.

Thus, these are the similarity between mars and earth.
