According to the diagram below of eukaryotic gene expression, what can be correctly inferred?
A) transcription does not occur without the enhancer sequence
B) levels of transcription are unaffected by the presence of an enhancer
C) enhancer sequences only work in one configuration with the promoter to cause transcription
D) the levels of gene expression can be controlled by segments of DNA far away from the actual gene

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite
