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.

Climate does not effect the rate in which weathering can occur. true or false
Mashcka [7]
This statement is false. Climate does affect the rate which weathering will occur.  Weathering will occur when there is a physical or chemical process to the landscape. Freezing and thawing will turn minerals, like silicate, into clay. When the weather is hot it causes faster chemical weathering than it would in say colder locations. Rocks will also break down faster in a wet climate. So, climate can effect the rate of weathering.

Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
