¿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.

Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
ad-work [718]

True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.

A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.

The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is  MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

What conditions are necessary in order to use a t​-test to test the differences between two population​ means?.
Sliva [168]

The two samples must be independent and each must be drawn at random from any population. The two samples must be independent and each must be drawn at random from a healthy population.

At the very least, nominal scale data are required. There must be normal populations. There must be knowledge of the two population standard deviations. The samples depend on one another.

<u>What is nominal scale?</u>

A nominal scale is a measurement scale that is used to categorize events or things into distinct groups. This type of scale only needs one-of-a-kind identifiers to mark each separate category instead of requiring the usage of numerical values or categories ranked by class.

Which of the following are limiting nutrients ?
OleMash [197]

Answer:

Nitrogen and Phosphorus

Explanation:

When the function of a whole ecosystem is limited because of a nutrient , which is present in limited amount, it is called as a limiting nutrient. The organisms uptake water and carbon directly from the environment as it is abundant in nature. The nutrients like nitrogen and phosphorous are present in limited amount and moreover they are not present in the form that can be directly taken up by the organism.

Thus, Nitrogen and Phosphorous are limiting nutrients.
