Elabora una hipótesis de: Los cometas habrían contribuido a la Tierra con moléculas orgánicas, como aminoácidos, hidrocarburos y
RUDIKE [14]

Answer:

Hipótesis: la vida está distribuida por todo el universo debido al trasporte de moléculas orgánicas a través de cometas interestelares 

Explanation:

En ciencia, una hipótesis es una explicación posible de una pregunta sobre algún fenómeno específico del mundo natural, la cual es corroborada (o refutada) a través de la aplicación del método científico. A través de técnicas de espectrometría, las cuales son capaces de medir con exactitud los espectros de absorción y de emisión de la luz de determinadas sustancias químicas, los científicos recientemente han determinado inequívocamente que los cometas pueden transportan concentraciones significativas de materia orgánica, es decir, aminoácidos y bases nitrogenadas como las que forman los bloques de construcción del ADN y ARN. En consecuencia, este tipo de observación puede llevar a plantear diferentes preguntas relacionadas al origen de la vida tales como, por ejemplo: ¿ la vida se originó en la Tierra a partir de la combinación de materia orgánica de origen extraterrestre?, o bien ¿la vida se encuentra distribuida en todo el universo gracias a cometas interestelares?. La 'panspermia' es una hipótesis que propone la existencia de vida esparcida por todo el Universo. Esta hipótesis está basada en la existencia de microrganismos extremófilos como aquellos que se encuentran en condiciones extremas de temperaturas, planteando que dichas formas de vida habrían quedado atrapadas en cometas los cuales habrían sido expulsados ​​al espacio como consecuencia de colisiones entre planetas que albergan vida.

Fungi are different from plants because _____
Lera25 [3.4K]

Here is your answer:

Fungi are different from plants because "they do not need sunlight to grow" most fungi could grow in harsh conditions and do not need sunlight to grow. Some grow deep in caves where there's no sunlight at all but still grow. Plant's need sunlight they cannot grow without it. Some fungi can even form and grow on humans, but plants can't.

Hope this helps!

A __________________ allows hydrogen ions to flow across the inner mitochondrial membrane.
yuradex [85]

The name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane is ATP synthase.

ATP synthase is a protein that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (Pi). It is classified under ligases as it changes ADP by the formation of P-O bond (phosphodiester bond). ATP synthase is a molecular machine.

The overall reaction catalyzed by ATP synthase is:

ADP + Pi + 2H+(out)    ⇌      ATP + H2O + 2H+(in)

The formation of ATP from ADP and Pi is energetically unfavorable and would normally proceed in the reverse direction. In order to drive this reaction forward, ATP synthase couples ATP synthesis during cellular respiration to an electrochemical gradient created by the difference in proton (H+) concentration across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria. During photosynthesis in plants, ATP is synthesized by ATP synthase using a proton gradient created in the thylakoid lumen through the thylakoid membrane and into the chloroplast stroma.
