<h2>A) option is correct </h2>
Explanation:
- RNA is a linear polymer of ribonucleotides
- Sugar in RNA is ribose instead of deoxyribose which is present in DNA
- The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
- RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
- Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix
I think the answers is B but I'm not 100% sure
La relevancia de la ciencia y su misión social se logra gracias a la posibilidad de un conocimiento teórico capaz de penetrar cada vez con mayor profundidad en el conocimiento de la realidad, lo que se expresa a través del proceso de investigación científica, cuando se revelan los nexos esenciales.
Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.
