During photosynthesis, specific pigments absorb light energy, which is then used to fuel the building of sugar molecules. Which

Andreas93 [3]

Answer:

Chlorophyll a- violet blue

Chlorophyll b - orange red

Carotenoids- green yellow

Explanation:

The three major plant pigments are chlorophyll a, chlorophyll b and carotenoids.

Various pigments are identified by their specific pattern of wavelength absorption in the spectrum of visible light. Chlorophyll a absorbs light in the violet-blue region, while chlorophyll b absorbs orange-red light. Chlorophyll a and b reflects or transmits green light hence they appear green. Carotenoids absorb light in the green - yellow region hence they reflect longer yellow, red, and orange light.

lyudmila [28]

Answer:

Phase III

Explanation:

The given condition fall in the trial phase (Phase III) of cinical study which aims to:

- Determine drug's effectiveness (primary goal)

- Determine long-term drug safety

- Confirm findings

In Phase III, randomised, double-blind, placebo-controlled, parallel group study is majorly to evaluate the efficacy and safety of placebo in episodic migraine prevention in children (6 to < 12 years of age) and adolescents (12 to < 18 years of age).

The trial consists of four phases: screening; double-blind therapy period for 24 weeks in which placebo or Erenumab is given to subject as dose 1, dose 2 or dose 3 (based on the participant's body weight) once a month via subcutaneous injection; optional dose level blinded extension phase (40 weeks) which involves subjects recieve dose1, 2 and 3 of placebo, and at last it follows a safety follow-up phase for 12 weeks (after 16 weeks of the last dose of investigational drug).

Hence, the clinical phase is phase III.
