Answer:

The correct answer would be group D- 809 kg.

It can be explained with the help of pyramid of biomass.

Pyramid of biomass represents biomass or the amount of organic or living matter present at each trophic level in an ecosystem.

The amount of organic matter is usually expressed in grams per meter square (g/m²).

There are usually four trophic levels in the pyramid of biomass: primary producers, primary consumers, secondary consumers, and tertiary consumers.

Usually, the biomass decreases as we go up the trophical levels specially in terrestrial ecosystem. Inverted pyramid can be observed in case of aquatic ecosystem (biomass of phytoplanktons is less than that of herbivores).

Here, maximum biomass (809 kg) belongs to the group D and hence, it would belong to primary producers.

En un cruce entre peces naranjas y peces grises se obtiene una generación (f1) de 50% peces grises . Realice el cruce y explique

Ilya [14]

Answer:

Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).

Explanation:

Datos disponibles:

Cruce entre peces naranjas y peces grises
50% de la F1 son peces grises
Naranja dominante sobre gris

Podemos nombrar el alelo dominante para color naranja N, y al alelo recesivo para color gris n.

Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.

Supongamos que uno de los parentales lleva el genotipo Nn, y el otro parental es nn.

Cruce:

Parental) Nn x nn

Gametas) N n n n

Fenotipos) Naranja Gris

Cuadro de Punnett) N n

n Nn nn

F1) 2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn

2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,

50% de la progenie será color naranja (Nn)

50% de la progenie será color gris (nn)

Cholesterol is a ________, which ________. steroid; is a component of eukaryotic membranes steroid; is the basis for many animal

olasank [31]

Answer:

Steroid; is a component of eukaryotic membranes.

Explanation:

Cholesterol is one of the most important chemical synthesized by all the animals. The chemical formula of cholesterol is C27H46O. The cholesterol in solid state was first given by C27H46O.

Cholesterol is present in the plasma membrane and maintain its membrane fluidity. Cholesterol is an important structure of the plasma membrane and acts as a pre cursor for various hormone. The cholesterol is a type of sterol and a lipid.

Thus, the correct answer is option (1).
