Answer:
Option A. inducer.
Explanation:
The lac operon is an inducible operon. The presence of lactose allows the gene expression for the metabolism of lactose. The IPTG mimics the structure of allolactose. The allolactose is the direct inducer of the gene of lac operon. Lactose by converting to allolactose act as a inducer. The repressor in the lac operon binds with the operator region and thus inhibits the process of transcription.
The allolactose binds with repressor and thus inhibits its binding to operator thereby initiating the process of transcription. As the IPTG mimics allolactose so it binds with repressor and act as a inducer. Thus, option A is correct.
Yes a small cell has a larger surface area
Answer: Cancer can spread anywhere through the body, but it's most likely to spread to lymph nodes, bones, the brain, the liver or the lungs.
Explanation:
The American marten is a long, slender-bodied weasel about the size of a mink with relatively large rounded ears, short limbs, and a bushy tail. American marten have a roughly triangular head and sharp nose. Their long, silky fur ranges in color from pale yellowish buff to tawny brown to almost black.
Decreased pH would increase the amount of oxygen unloaded by hemoglobin into peripheral tissues.
<h3>What is hemoglobin?</h3>
- The iron-containing oxygen-transporting metalloprotein known as hemoglobin.
- The abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs.
- The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
- Iron deficiency anemia is characterized by low hemoglobin that is brought on by low iron levels.
- Low hemoglobin is most frequently caused by a diet that is inadequate in iron.
- Low hemoglobin levels can cause headaches, exhaustion, and pale complexion.
- Surgery, iron therapy, and iron supplementation are all options for treating low hemoglobin.
- Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.
- A low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia).
