Answer:
transcription requires a specific combination of transcription factors
Explanation:
Combinatorial control refers to a regulatory mechanism in eukaryotic transcription that involves several transcriptional factors. Simply saying, in eukaryotes, expression of a gene is controlled by specific combinations of transcriptional factors. This also means that one factor can be involved in regulation of two distinct genes but in combination with different other factors.
Combinatorial control is one of the examples which shows the complexity of gene regulation in eukaryotes over the prokaryotes.

If natural selection changes then the phenotypes within a population changes over time because natural selection acts on phenotypes instead of genotypes .
Answer:
easy ......
This statement means that the flow of nutrients is not unidirectional in an ecosystem, i.e. the nutrients do not flow in one direction. ... Example: Nutrients that are passed on from the plants to herbivores and then to other organisms are recycled back into the atmosphere after that organism.
