Mamont248 [21]

Explanation:

Cultivar tus propios alimentos puede ser una tarea que da satisfacción y fomenta la alimentación sana, orgánica y libre de pesticidas.

Los recursos imprescindibles para el cultivo de alimentos son la elección de los alimentos que se quieren cultivar y a partir de ahí elegir el suelo ideal para el desarrollo de las plantas, utilizando compuestos que se pueden preparar en casa como compost orgánico a base de piel de vegetales.

También es necesario elegir la forma a plantar, ya sea mediante plántulas, semillas, tubérculos, etc. Es importante recordar que es fundamental que utilices agua de calidad para regar tu suelo para que no haya contaminación de los alimentos.

También es fundamental que el cultivo se realice en un ambiente con exposición a la luz solar, para que exista el eficaz desarrollo y producción de carbohidratos a través de la fotosíntesis.

Svetradugi [14.3K]

Answer:

Spinach leaves would be helpful to replace damaged heart tissue because they can replace the damaged blood vessels with the ones that the leaves have.

As a result, the tissue will grow from this. The goal is to replace damaged tissue using leaves, this has not been successfully done yet, but scientists have made improvements in this area.
