Answer:
the mesopelagic, dysphotic, or twilight zone
Explanation:
Marine zones are the divisions of the ocean. The ocean is divided into two basic parts; the pelagic or open ocean, and the benthic or sea floor.
The pelagic zone is further divided into five broad zones according to how far down sunlight penetrates and they are:
1) the epipelagic, euphotic, or sunlit zone: the top layer of the ocean where enough sunlight penetrates for plants to carry on photosynthesis.
2) the mesopelagic, dysphotic, or twilight zone: a dim zone where some light penetrates, but not enough for plants to grow.
3) the bathypelagic, aphotic, or midnight zone: the deep ocean layer where no light penetrates.
4) the abyssal zone: the pitch-black bottom layer of the ocean; the water here is almost freezing and its pressure is immense.
5) the hadal zone: the waters found in the ocean's deepest trenches.
Answer:
5.00×10-19 J
Explanation:
E = hv
but v = c ÷ wavelength
E = (6.626×10-34) × ((3×10^8)÷(398×10-9))
= 4.9945×10-19
≈5.00×10-19
Hope this helps
Answer:
1. 0.05moles of H₂O₂ is consumed in the reaction
2. the number of unreactive H₂O₂ is 0.20 moles
3. the percentage of H₂O₂ is 0.18%
4. no, not similar to 3% H₂O₂
5. percentage error = 0.94 = 94%
Explanation:
Answer: B More biodiversity -> Better chance for an ecosystem to sustain itself
