Concept explainers
To explain: The reason for which the growth of photosynthetic protists and prokaryotes decreases in tropical and mid-altitude oceans.
Introduction: The protists are essential and play a key role in the ecological community. Mostly, the protists are aquatic and are found in the places like leaf litter and damp soil. Thus, protists are the essential producers (photosynthetic protists).
To explain: The effect of decreasing growth of photosynthetic protists and prokaryotes in tropical and mid-altitude oceans on marine ecosystems and the global carbon cycle.
Introduction: Every organism depends upon these producers for their food, whether indirectly or directly. It is estimated by the scientists that 30% of the photosynthesis in the world is performed by the dinoflagellates, diatoms, various aquatic protists and the multicellular algae.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?
