In the early 20th Century, astronomers thought that the Milky Way Galaxy was the entire universe. In fact, they considered spira
qaws [65]

Answer:

Explanation:

Based on the scenario being described within the question it can be said that the most likely reason for this misconception would be that the spiral galaxies looked like clouds of gas and dust through telescopes because of their distance from Earth. During that time telescopes were still not as advanced and could only see so much, nowadays they are much more advanced and these galaxies are being analyzed and understood more clearly.

ArbitrLikvidat [17]

Answer:

1.Ratón: se ubica en el segundo nivel trófico, es un consumidor primario que se alimenta de semillas

semillas (productores)---->ratón (consumidor primario)-->serpiente(consumidor secundario) --->zorro(consumidor terciario)

2.

  • Hay 4 niveles tróficos.
  • En el primer nivel se encuentran los productores.
  • En el segundo nivel se encuentran los consumidores primarios, estos se alimentan de los productores.
  • En el tercer nivel se encuentran los consumidores secundarios, los cuales se alimentan de los consumidores primarios
  • En el cuarto nivel se encuentran los consumidores terciarios que se alimentan de los consumidores secundarios.
  • Al consumir lo que se encuentra en el nivel anterior obtienen energía para subsistir y mantener el equilibrio del ecosistema.
  • Los niveles tróficos son los lugares que ocupan un determinado grupo de seres vivos en relación a otros por la energía que tienen y que pasan al siguiente nivel. Se ve en la cadena alimentaria, donde la energía que se obtiene de los nutrientes del nivel anterior siempre es destinada a seres mas grandes en tamaño, es decir que están en el siguiente nivel trófico y necesitan mas energía.

Explanation:

El ratón es un animal herbívoro, es decir que se alimenta de plantas y hierbas, por ende se ubica en el segundo nivel trófico porque consume a los productores. Estos últimos reciben este nombre porque producen su propio alimento a diferencia del resto de los niveles en donde los seres vivos se alimentan de animales o insectos que estén en niveles inferiores.

La energía que obtiene el ratón al consumir a los productores se utiliza en el metabolismo y en las diferentes reacciones que hacen que se mantenga vivo hasta que este es consumido por otro animal transfiriendo la energía al siguiente nivel. Esta cadena sigue hasta llegar al consumidor terciario. En todos los niveles intervienen los descomponedores que degradan los restos de los seres vivos para obtener energía y nutrir la tierra, de esta forma comienzan nuevamente la cadena alimentaria.

Structure of Water and Hydrogen Bonding

  • living systems depend on water and its polarity as well as hydrogen bonds
  • hydrogen bonds result in the cohesion: ability for water molecules to stick together through hydrogen bonds, adhesion: ability for polar part of water to stick to other polar surfaces and surface tension: water's attraction to each other in bonds rather than air so have tension on surface
  • cohesion of water is the Attraction between molecules of the same substance.
  • Hydrogen bonds between the oxygen of one water molecule and a hydrogen of another water molecule.
  • Adhesion of water is the property of water to attract with other substance.
