These organisms obtain energy through chemosynthesis rather than photosynthesis

Biology
1 answer:
ASHA 777 [7]3 years ago
8 0

Answer:

Autotrophs

Explanation:

Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.

Al cruzar 2 moscas negras se obtiene una descendencia formada por 216 moscas negras y 72 oscuras blancas. A) Razone el cruzamien
Kipish [7]

Answer:

Fenotipo: Moscas negras y moscas blancas.

Genotipo: Nn y nn.

Explanation:

Sabemos que al cruzar dos moscas un pequeño porcentaje de su descendencia es blanca y la mayoría negra. Por ende, hay dos alelos distintos para el color, uno codifica para moscas de color negro y el otro para las de color blanco. Como la mayoría de la descendencia es negra, el gen domiante es el negro, a este lo denominaremos con la N y al recesivo con la letra n.

Para que haya moscas blancas, las dos moscas que se cruzan tienen que ser Nn, es decir, su genotipo tiene que ser heterocigoto. Podemos verificar esto con un cuadro de Punnett:

<u>   ║N  ║n</u>

<u>N║NN║Nn</u>

<u>n║Nn ║nn</u>

Con el cuadro de Punnet vemos que la descendencia tiene los genotipo, es decir, los genes que un ser tiene, Nn y nn. El fenotipo, es decir, lo que podemos ver de los genes, sera moscas de color negro y moscas de color blanco.

Como el gen dominante es el negro, cualquier mosca con este gen expresara este color y solo las moscas con genotipo h0m0cigoto (nn) expresaran el color blanco.

When grass is randomly distributed throughout an environment, a population of deer that eats grass is most likely to have a ____
Bas_tet [7]

Answer:

Random distribution.

Explanation:

The distribution of the population in space across an area is largely driven by the food and other resources in the environment. Uniform, random and clumped are the main distribution pattern.

The grass is distributed randomly in the environment, the population of deer is most likely to have random distribution pattern. Since, the distribution pattern depends upon the food resources so the deer have random distribution in space.

Thus, the correct answer is option (D).
