Answer:

The all possible gametic haplotypes that can be made are described below.

Explanation:

According to the question, F1 progeny was produced by crossing a homozygous dominant parent with a homozygous recessive parent. As per the question, cross is to be made with a heterozygous parent, which will have solid unpatterned allele and blue colour with a homozygous recessive i.e lined, aqua lizard.

The possible haploid gametes for the heterozygous parent would be BL, bl, Bl, bL and for homozygous parent would be all bl.

As a student in an environmental science class, you have been asked to explain the greenhouse effect and the problem we face, in
ser-zykov [4K]

C) The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.

Explanation:

The increase in greenhouse gas emission cannot be likened to placing an extra log on the fire to produce more heat.

In essence, the earth is not receiving more heat than usual from the sun. It is not getting more heated.

  • Greenhouse gases prevents heat from being lost from the earth surface as long wave radiation.
  • This in turn will warm and heat the earth surface.
  • The more the greenhouse gases, the more heat that is trapped within the earth.
  • The greenhouse gases is the cover that prevents heat from being lost.
  • Global warming is what results.
  • An increase in heating might not cause warming of the house if the house is open.
  • So also, if the earth receives more energy from the sun, the temperature might not increase if no greenhouse cover is available.

Other analogies shows heating(global warming) and cover(greenhouse gases) except of C.

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.
