A watt IS by definition a J/s so and so an 18000 W station will use 18000 J/s so it is C
Answer: D. Galaxies show a red shift, indicating they are moving away from each other.
Explanation:
Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.
This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.
Answer:
(c) their inclusiveness.
Explanation:
The taxonomic classification has eight levels, they go from the more inclusive to the more exclusive.
The eight categories are: <u>Domain</u> which is the most inclusive level, that is to say, that the largest number of individuals are included in this level. There are three domains according to the cells types, and where they live. They are the Eukarya, Bacteria and Archaea. Domains are divided into <u>kingdoms</u>, they are the Plantae, protista, Eubacteria, Archaebacteria, Animalia and Fungi. After kingdoms the <u>Phylum</u> category comes, following Phylum is <u>Class</u>, various classes that are related will form a Phylum. The next category is <u>Order</u>, order is divided into <u>Family,</u> families are broken into <u>Genus</u>, where species are closely related between each other and finally the last category is <u>Especies identifier,</u> in this group there are unique characteristics that will identify a specie. With this classification we can see that we go from global groups to more specifics ones as the classification avances.
Answer:
- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio
- Limitación metabólica: en principio no existen limitaciones metabólicas
Explanation:
La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.
When the bond between the second and third phosphate group is broken in ATP, ADP is formed and energy is released. This energy can power the cell's functions.
