¿Qué áreas del conocimiento me pueden <br> aportar a la ejecución del proyecto? para un huerto
tensa zangetsu [6.8K]

Answer:

Conocimientos que pueden resultar muy útiles al momento de planificar un huerto:

- biología vegetal (características de las plantas que queremos producir)

- agronomía (características del terreno utilizado)

- condiciones ambientales (meteorología), como así también la disposición del lugar

Explanation:

Para iniciar un huerto en casa es necesario tener en cuenta una serie de factores que pueden influenciar en gran medida el éxito del proyecto:

-Tener en cuenta las características de las plantas que queremos producir es fundamental para lograr un óptimo crecimento. Por ejemplo, plantas que no resisten las heladas podrían morir en ciertas regiones, con lo cual las plantas deberían encontrarse en estos casos protegidas durante su desarrollo (por ejemplo, mediante un invernáculo).

- Buscar lugares bien iluminados. La presencia de luz es un factor fundamental para el crecimiento de las plantas.

- Riego y/o precipitaciones: tener en cuenta las necesidades hídricas de las plantas que queremos producir.

- Suelo: utilizar tierra abonada suele ser la mejor opción para brindarle a las plantas la mayor cantidad de nutrientes y así garantizar un óptimo crecimiento. En el caso de usar macetas, la presencia de huecos o el uso de vermiculita puede ser de gran ayuda para permitir la escorrentia del agua.

- Espacio: es necesario tener en cuenta el espaciado entre plantas para que puedan crecer normalmente.

-Tener en cuenta las plagas (insectos, nemátodos, etc) que podrían afectar el crecimiento de las plantas.

If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

Answer:

Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.

Explanation:

In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.

These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.

These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations

It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.
