ATP stands for Adenosine Triphosphate. The bond between the __________ (first, second, or third) phosphate group and the _______
polet [3.4K]

Answer:

The bond between the _second_________ phosphate group and the third__phosphate group is a high energy bond.

Explanation:

Adenosine triphosphate is a nucleotide with three phosphate groups.  The second and third phosphate groups are bonded by high energy covalent bonds to the rest of the ATP molecule, which consists of a sugar, which is ribose, the first phosphate group, and the nitrogenous base which is adenine. All of the phosphate groups are negatively charged and repel each other, so a high energy covalent bond is necessary to attach these phosphate groups together and keep the forces from pulling them apart.

Redacta un escrito dónde expliques como está formado(un ecosistema), menciona ejemplos y como sigue una estabilidad por el equil
IceJOKER [234]

Answer:

Un ecosistema esta formado por facotres abioticos y bioticos.

Los factores bioticos son aquellos que presentan signos vitales, es decir que cumplen con la vida, metabolismo, respiracion, entre otras funciones vivas.

Los factores abietos son aquellos que no tienen vida pero con los que los factores bioticos intercambian energia, un ejemplo de esto son las rocas, los vientos, los sedimentos, la tierra fertil.

Los factores bioticos serian los organismos vivos como los animales, que al funcionar como sistemas abiertos de intercambio de energia constante mantienen un equilibrio fisico biologico con los factores bioticos.

Explanation:

Los ecosistemas cumplen con una cadena que no debe romperse ni faltar ningun eslabon, si esta continuidad se interrumpe con la extincion de una especie como animal o vegetal el ecosistema variará, y cambiara toda su conformacion.

Es un conjunto de factores bioticos y abioticos en armonia que se complementan e intercambian energia entre si de manera ordenada en eslabones, si uno de estos eslabones se rompe, se extingue, o se modifica por intervencion del hombre u otros factores TODO el escosistema se verá modificado o afectado.
