Olá!!! Bom vamos lá!
O nucleotídeo é constituído de um açúcar,um grupo fosfato e uma base nitrogenada. Nesse caso estamos falando de subunidade então podemos dizer que estamos falando do RNA ou DNA, logo, teremos a desoxirribose como açúcar.
Depois teremos um grupo fosfato e assim as bases nitrogenadas ( Guanina, Timina/Uracila, Citosina, Adenina) Sendo que C combina com G e A combina com T/U , vamos usar a base T quando for DNA, e quando for RNA vamos usar U. Por isso a resposta correta é a letra B!
Espero ter ajudado em algo!

<h3>What are erector spinae muscles?</h3>
The <em>erector spinae</em> muscles are a group of different muscles and mainly consist of 3 muscles. i.e., the <em>spinalis </em>muscle, <em>longissimus </em>muscle, and <em>iliocostalis </em>muscle.
<em>The </em><em>erector spinae</em> muscles is a muscle group located at the back, bilaterally along the spine.
The <em>erector spinae</em> serves to extend the back at the hip, thereby producing the torso being pushed upward.

Answer:old earth:
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today.At its beginning, Earth was unrecognizable from its modern form. new earth:
"Today's Earth (TE)" is JAXA's land surface & river simulation system developed under the joint research with University of Tokyo. The system distributes & visualizes various hydrological products and their magnitudes for disaster monitoring and hydrological research.
The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
