Q? Describe the concentration gradient of carbon dioxide across the cell membrane.

hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

$CO_{2}$ undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells

Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.

when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.

Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.

Las vitaminas y minerales son micronutrientes esenciales que deben ser consumidos a través de la dieta parra llevar a cabo funciones metabólicas y fisiológicas diarias. Es importante destacar que existe una excepción a esta regla: la vitamina D puede ser sintetizada por células de la piel mediante una adecuada exposición a la luz del sol. Todos los alimentos destacados en las opciones mencionadas son ricos en determinados grupos de vitaminas y minerales:

- Cereales: ricos en vitaminas del grupo B y minerales, principalmente fosforo y potasio

- Tubérculos (por ej., la papa y la batata): ricos en vitaminas A y C, y minerales, principalmente potasio, fósforo y magnesio

- Leguminosas: ricos en vitaminas del grupo B y vitamina C, y minerales tales como potasio, hierro y magnesio

- Frutas y Verduras: ricos en vitaminas de todos los grupos y minerales esenciales tales como potasio, hierro, magnesio, fósforo, calcio, zinc, etc.
