I think it's D I'm not sure
Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.
The correct answer is D: The seeds develop inside a fruit.
A heterotroph is a animal who can't fix carbon and uses organic carbon for growth.
