Hi,
The answer should be ‘concentration’.
The answer is <span>D.regeneration</span>
The Calvin Cycle is characteristic for photosynthetic organisms. It consists of three phases - carbon fixation, reduction, and regeneration. In the second phase, reduction, 3-phosphoglyceric acid (PGA) is reduced to glyceraldechide-3-phosphate. Further, in the third phase, regeneration, some of G3P are removed from the Calvin Cycle to be converted to glucose and other carbohydrates.
Land plants are evolved from green algae.
Green algae called charophytes are coolest relatives of land plants.
It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans. Not only do both land plants and green algae produce chlorophyll a and b, but other evidence suggests that there is a relationship as well.
4 key traits that appear in nearly all land plants but are absent in the charophytes.
-Diploid embryos
- The ability to photosynthesize
-Apical meristem
-Walled spores produced in sporangia.
- Multicellular haploid and diploid generations
-Multicellular gametangia

Answer:
B. First 200 feet
Explanation:
The first 200 feet deep zone of the ocean is termed as Photic Zone of the ocean because this zone receives sufficient quantities of light so that the phytoplanktons that are found in this are become enable for Photosynthesis. This zone is critically important because we know that phytoplanktons are the primary producers in oceans and the food web of the ocean starts with these phytoplanktons. This zone is considered to be the area of highest net primary productivity.
