Answer:
Nucleus
Explanation:
In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.
Once an RNA has been produced, by transcription and processing the information present in its nucleotide sequence is used to synthesize a protein.
Answer:
The alteration of a river's flow and sediment transport downstream of a dam often causes the greatest sustained environmental impacts. Life in and around a river evolves and is conditioned on the timing and quantities of river flow. A dam also holds back sediments that would naturally replenish downstream ecosystems.
