Phytoplankton are plantlike microorganisms that live on the water's surface in aquatic biomes. As photosynthesis organisms, phyt
oplanton produce much of Earth's oxygen as a byproduct. Explain the ecological impact of a decline in phytoplankton by providing examples from the organism through the ecosystem levels of organism.
Phytoplankton serves as food for virtually all the organisms living in an aquatic environment. It is a primary food producer and serves as the foundation of aquatic food web. If there is a decline in the amount of phytoplankton, the organisms which feed directly on the plant may reduce significantly as a result of dire competition for food, this in turn will affect the organisms which feed on the dying out organisms and the trend will move in a similar way until it affect all the organisms living in that particular aquatic habitat.
The origin of replication in E.coli is called the oriC
This region is rich in Adenine and Thymine bases because their base stacking interactions are weaker than those of Cytosine and Guanine.
Between A and T bases there are only 2 hydrogen bonds (not a very strong interaction so requires less energy to separate) while between C and G bases there are 3 hydrogen bonds (strong interaction thus requires more energy to separate)
The oriC is a region which needs to be separated when replication occurs. It is thus a region which requires easy separation with as little energy as possible so that proteins like DnaA can bind.
Greater than 95% of iron in plasma is bound to its circulating transport protein transferrin, which delivers most of its iron to erythrocyte precursors—i.e. erythroid progenitor cells of the bone marrow that differentiate into mature RBCs
