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.

You observed light passing through lenses and through a set of prisms. Why does refraction occur? Include your lab observations
lara31 [8.8K]
I don't have your lab observations, but I can give you the reason why refraction occurs.

Refraction refers to the bending of light at the interface as it passes through mediums of different densities.

Refraction occurs because light travels at different speeds in mediums with different densities.

Hope this helps!

A body of fresh water is shown below.
Triss [41]

Answer:

Point D

Explanation:

Point D is the point that is most likely to not have any plants growing in it. The reason why this point of the body of water will not have any plants is because of the lack of light. This part of the body of water is dark, with no light penetrating to it. The plants need light to survive, as it is a vital element in the process of photosynthesis. If there isn't any light, the plants can not perform photosynthesis, thus they can not produce their own food, which in turn means that they will not exist in such a place.

What is the process of the cellular division that separates homologous chromosomes from one another?
nataly862011 [7]
For meiosis, this is in anaphase I. For the separation of sister CHROMATIDS in mitosis, this is anaphase. Either way, the separation of two whole chromosomes or two chromatids within one whole chromosome takes place during anaphase. This occurs after metaphase and before telophase and cytokinesis.
