Plants maintain higher levels of phytochrome at their growing tips where phytochrome plays important roles in growth responses to light. Phytochrome levels are also high in areas of the plant that are "greening". What does this suggest about the role of phytochrome in these "greening" zon?

Phytochrome is facilitating the transcription and translation of photosynthesis related proteins

Explanation:

Phytochromes are a type of photoreceptors usually seen in fungi, bacteria ad in plants generally. They hep these organisms for the detection of light. They have a high level of pytochrome and this plays a very vital role to ensuring that plants grow as they see light. Also, for areas of plants that already have "green zones", phytochrome also plays a criucial role in this greening.

i’m   sure probably just geuss and see which one you can get right, i’m pretty sure it is the combination of goods and services

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
