Correct answer: B). They can be transformed into any type of body cell.
The stem cell is the biological cell that has the ability to differentiate into other types of cell. These are always found in the multi-cellular organism. These cells are known to be the foundation of every tissue and organ in our body. Embryonic stem cell is pluripotent, it means they can give rise to every type of cell in the body.
Example: Hematopoietic stem cells that give rise to all type of blood cells like red blood cells, white blood cells etc.
Hence, the correct answer would be option B.
Nitrogen forms NUCLEOTIDES that are part of DNA, as well as amino acids, which help build proteins. Nucleotides are building blocks of DNA.
<h3>Nucleotides and DNA</h3>
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long strands of building blocks called nucleotides.
In DNA, there are four types of nucleotides that contain different nitrogenous bases: Adenine, Cytosine, Guanine and Thymine.
The nitrogenous bases are composed of nitrogen and they are fundamental to form nucleotides (nucleotides consist of one nitrogenous base, one sugar and one phosphate group).

Answer:
We call it
Double circulation bcoz their are 3 circulation exist between heart, lungs and body organs.
EXPLANATION :
Flow of blood is left to right
1. Pulmonary circulation
<em>Right</em><em> </em><em>ventricle</em><em> </em><em>-</em><em>pulmonary</em><em> </em><em>artry</em><em> </em><em>-</em><em> </em><em>lungs</em><em> </em><em>-</em><em> </em><em>pulmonary</em><em> </em><em>veins</em><em> </em><em>-</em><em> </em><em>left</em><em> </em><em>artria</em><em> </em>
2. Systemic circulation
Left ventricle - systemic artry - body organs - systemic veins- right artria
I think the correct answer from the choices listed above is option A. <span>When there is no lactose present in the body, the repressor protein blocks RNA polymerase from binding to the promoter, making transcription impossible. Hope this answers the question. Have a nice day.</span>
Yes it’s called ice wedging you’re correct
