Why a entrophic body of water has high biological productivity

1 answer:

8 0

A body of water that has experience eutrophication has way to many nutrients and minerals in it. This is caused from factory, agriculture,and road run off. It causes an excessive growth of plants in the body of water basically. Some of the minerals and nutrients include Sodium triphosphate and Phosphorus

Which of the following statements concerning prokaryotic cells are true? Check all that apply.

Firdavs [7]

Answer:

They are typically smaller than eukaryotic cells.

The DNA of a prokaryotic cell is contained in the nucleoid.

Explanation:

There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.

does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in pork

Leona [35]

Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.

Explanation:

DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.

Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA. In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).

In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD,SINOQUE YANDIEN PUEDEN SER E________.AMENUDO SE DISFRASAN CON

Semenov [28]

La respuesta correcta para esta pregunta abierta es la siguiente.

Desafortunadamente, no anexaste opciones o incisos para responder la pregunta. Sin embargo, podemos comentar lo siguiente.

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD, SINO QUE TAMBIEN PUEDEN SER ENGAÑOSOS. A MENUDO SE DISFRAZAN CON NOMBRES QUE PUEDEN SER SABROSOS.

Es muy importante que seas cuidadoso con los alimentos que consumes como parte de tu alimentación. Muchas empresas, a través de sus marcas, comparten publicidad engañosa para atraer más clientes bajo la promesa de alimentos sabrosos y nutritivos. Y la verdad es que no. Te están engañando.

No hay nada como basar tu dieta diaria en frutas, verduras y un equilibrio entre proteínas, carbohidratos, azúcares naturales y grasas.

Si es necesario, consulta a tu médico o a un nutriólogo para que te expliquen qué tan malo pueden ser los alimentos con muchos químicos.

¿Son sabrosos? Sí, pero también están llenos de sal, grasas, azúcares en excesos que le hacen mucho daño a tu salud.

En México ya existe una ley que obliga a todos los productos colocar unas etiquetas de color negro con blanco en todos los productos con la leyenda: "exceso de sodio," "exceso en grasas," exceso en azúcar."

Esto, con el propósito de que la gente se entere antes de comprarlos.
