Which shows the correct order of steps involved when auxin affects plant growth?
elixir [45]

Answer:

3, 1, 4, 2

Explanation:

The effects described are called phototropism, where light affects the direction of growth of the plant.

Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.

Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.

This causes the plant to bend towards the light.

The specific method is to construct pH gradient inside and outside the liposome, and then use the solubility difference of ionizable drugs under different pH conditions to realize the drug loading. With this method, the drug encapsulation rate can reach more than 95% and the drug loading can reach about 10%.

¿Qué tipo de célula apareció primero en la Tierra?:___, y se presentan en seres vivos como las:___ y se caracterizan porque:___.
Levart [38]

Answer:

Célula procariota y procariotas.

Explicación:

La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
