They are both known to be heavy, hydrogen is one of the two stable isotopes of deuterium
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus. They have the same number of sets of chromosomes, one set in the case of haploid cells and two sets in the case of diploid cells. In most plants and all animal species, it is typically diploid cells that undergo mitosis to form new diploid cells. In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new haploid daughter cells. The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only. This is half the number of chromosome sets in the original cell, which is diploid.
<span>¡La opinión de un químico sobre el mundo no es tan estrecha como se podría pensar! Sí, empezamos con el átomo, y luego pasamos a las reglas que gobiernan los tipos de unidades estructurales que se pueden hacer con ellos. Se nos enseña tempranamente a predecir las propiedades de la materia en masa de estos arreglos geométricos.
Y luego llegamos a H2O, y estamos sorprendidos al descubrir que muchas de estas predicciones están muy lejos, y que el agua (y por implicación, la vida misma) ni siquiera debería existir en nuestro planeta. Pero pronto aprendemos que esta pequeña combinación de tres núcleos y ocho electrones posee propiedades especiales que lo hacen único entre los más de 15 millones de especies químicas que conocemos actualmente. Cuando nos detenemos a reflexionar sobre las consecuencias de esto, la química pasa de ser una ciencia arcana a un viaje de maravilla y placer mientras aprendemos a relacionar el mundo microscópico del átomo con el mundo mayor en el que todos vivimos.</span>
<span>The term used when a mother makes the decision to terminate a pregnancy is abortion. This term means that the pregnancy will come to an end via removing the embryo or fetus prior to any time that it is capable of surviving on its own outside of the uterus.</span>
Answer:
The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.
