Answer:
The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.
A.
contracts to move substances through the body
D.
breaks down food to acquire nutrients
It would be B.) ospreys; decomposers
Since ospreys eat nothing but fish, if all of the trout died from a disease, the ospreys wouldn't have anything to eat because all of the fish are dead. This results in a loss of energy for the ospreys.
However, decomposers would gain more energy because they gain their energy from dead creatures, in this case, it would be the trout.
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed
THE ASNWER IS Photosynthesis.
