The correct answer is C. To block UV radiation. Ozone filters the majority of UV spectra, so it protects organisms from its effects.
Ummmmm....idk, can you let me know when you find the answer?
Answer:
cells connecting to each other in colonies and communicating.
Explanation:
Density is mass of object per unit volume
Answer:
blue is the most efficient while green is the least efficient
Explanation:
It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.
