Answer: the three objects are not always in exactly the same plane
Explanation: the diagram shows two dimensions. There is also variation in the third dimension. The Moon’s orbit is tilted relative to the sun earth plane
B. Mesozoic and Paleozoic
-Good luck!
Answer:
Si, esto es posible ya que para llegar a su forma madura el ARN mensajero sufre un procesamiento conocido como empalme alternativo donde su longitud se reduce drásticamente mediante la eliminación de regiones no codificantes (intrones) presentes en el trascripto primario
Explanation:
En células eucariotas, la transcripción refiere al proceso donde un gen es usado como templado para generar un ARN mensajero (ARNm) inmaduro conocido como pre-ARNm, el cual contiene regiones cortas codificantes (exones) y regiones largas no codificantes (intrones). Durante el proceso de empalme alternativo, también conocido como <em>splicing</em> alternativo, este pre-ARNm sufre un procesamiento mediante el cual los intrones son eliminados y los exones son retenidos y empalmados, con lo cual el ARNm maduro final reduce drásticamente su longitud original. En el caso arriba descripto, una proteína con 70 aminoácidos resultaría de la traducción de un ARNm maduro que posee 210 bases nucloetídicas, ya que cada triplete de nucleótidos o 'codón' corresponde a un sólo aminoácido agregado a la cadena polipeptídica durante la síntesis proteica en los ribosomas.
Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
Explanation:
- When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
- An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
- An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
- its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.
If an element has 1 valence electron, according to the Lewis dot diagram structure there would have 1 dot to represent that one valence electron.
