Answer:

Inosine

Explanation:

  • Inosine the unusual nucleoside which is found in tRNA but not in mRNA.
  • Inosine is derived from the nucleoside adenosine, adenosine is present in mRNA, however in case of tRNA, there is deamination of adenosine and thus, inosine is formed.
  • The enzyme that is responsible for carrying out this reaction is called as tRNA A:34 deaminases, here the position 34 indicates that the deamination takes place at position 34 of the tRNA.
  • The formation of inosine is essential for the wobble base pairing to take place.
  • The formation of inosine takes place when the hypoxanthine attaches to a ribose ring with the help of the beta glycosidic bond.

Tides are caused by the suns and the moons gravity pulling water away from the planet. When the sun, moon and earth are at right
Sunny_sXe [5.5K]

Answer:

When the sun, moon and earth are at right angles, this is called a neap tide.

When the sun, moon, and earth are parrallel to each other, this is called a spring tide.

Explanation:

There are two types of tides spring tide and neap tide.

A spring tide occurs when the sun and moon are parallel to each other. This usually happens during periods of full and new moon, which are the moments that the moon can form a straight line with the sun, causing the gravitational force to interfere with the tide.

The neap tide, on the other hand, happens when the sun, moon and earth are at right angles. This moment occurs between the waxing and waning moons, where the sun and moon are at right angles and the earth is used as a vertex of that angle. In this type of tide the gravity of the sun becomes more influential than that of the moon.

the corrective actions made by the bionic pancreas on a regular basis in response to changing blood sugar levels are similar to
Art [367]

The correct answer is: a feedback mechanism.

The bionic pancreas is bio-engineered device used for the regulation of blood sugar levels in order to maintain body homeostasis. The bionic pancreas includes a sensor that monitors blood sugar levels and sends a signal to a separate device that will then release the appropriate hormone into the bloodstream to return blood sugar levels back to normal. This device is very functional because of its ability to dose insulin and glucagon based on continuous sugar blood measurements.
