The percentage of germination of lettuce seeds exposed to far-red light, then blue light, and then red light compared to lettuce
Romashka-Z-Leto [24]

Answer:

<u>50%</u>

Explanation:

<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.

Please help me
Vlada [557]

Answer:

Ecological succession happens when new life takes over an environment. ... Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment

Ecological restoration aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. Disturbances are environmental changes that alter ecosystem structure and function. Common disturbances include logging, damming rivers, intense grazing, hurricanes, floods, and fire

Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate
