Answer:

A) Calcitonin injection

Explanation:

Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones. In osteoporosis, when the patient is given the injection of hormone calcitonin, it produces and increase in bone mass because it negatively affects the rate of absorption of bone by the osteoclasts.

ANTONII [103]

Answer:

the flavor will neutralize

Explanation:

if you're plugging your nose, it blocks most of the taste out of a food item. so while biting into an onion while plugging your nose, it will neutralize the strong flavor and make it taste more like an apple or potato since they have very similar textures. hope this helps!

A part of an mRNA molecule with the following sequence is being read by a ribosome: 5'-UGC-GCA-3' (mRNA). The charged transfer R
iren [92.7K]

mRNA codons determine which amino acid will be added to the growing polypeptidic chain. tRNA anticodons pair these codons and add the correct amino acid. <em>The </em><em>dipeptide</em><em> formed will be </em><em>Cysteine-Alanine</em><em>.</em>

------------------------------------------

Let us review a few points,

  • In protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction.

  • According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain.

  • A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly.

  • Each codon represents one amino acid used to build the protein.

  • Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid.

  • The anticodon is a short sequence of bases that pairs with mRNA codons.

  • tRNA adds amino acids following the codons sequence in the mRNA molecule.

  • The protein grows from the amino terminus to the carboxy terminus.

  • Adenine forms pairs with Uracyl ⇒ A↔U
  • Guanine pairs with Cytosine ⇒ C↔G

In the exposed example,

→ mRNA     ⇒  codons   ⇒ 5'-UGC - GCA-3'

→ tRNA       ⇒ anticodons ⇒  ACG  CGU

→ proteins  ⇒ amino acids ⇒  Cys     Ala ⇒ Codon UGC codes for Cysteine

                                                                     ⇒Codon GCA codes for Alanine

So, for the given sequence of mRNA, tRNA anticodons are ACG and CGU. And the added amino acids are <em>Cysteine and Alanine</em>.

Why doesnt plants and bacteria expand when it reaches water
kap26 [50]

When the plants and bacteria reach water, they get into a hypotonic solution means, the concentration of solutes is greater inside the cell than outside of it. When the plant and bacteria are placed in water, they take up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell become turgid. Turgidity means the cells are swollen and hard. The increase in pressure makes the cell rigid. This is why they do not expand and burst.
