Answer: blue range
Explanation:The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
Multicellular organisms arise in various ways, for example by cell division or by aggregation of many single cells. Colonial organisms are the result of many identical individuals joining together to form a colony. However, it can often be hard to separate colonial protists from true multicellular organisms, because the two concepts are not distinct; colonial protists have been dubbed "pluricellular" rather than "multicellular".

Answer:
<u>Benzodiazepines</u> are considered effective in the short-term treatment of anxiety, regardless of the cause.
Explanation:
Benzodiazepines are the group of CNS drugs which are used extensively in the attacks of anxiety alongwith insomnia and seizures because they have extremely fast acting anti-anxietic effects.
Benzodiazepines cause dose dependant CNS depression that extends from sedation to anesthesia to respiratory depression and death.
These drugs act on the GABA receptors and potentiate the effect of GABA thus resulting in the increase in the frequency of CL- channel opening thus mediate antianxiety and impairment of cognitive functions.
Benzodiazepines include following drugs :
1) Alprazolam
2) Diazepam
3) Lorazepam
4) Oxazepam
All of the above if that’s not a choice the third one sounds best
