Answer:
B. Many active genes are found in euchromatin, because proteins involved in transcription can easily access these regions of DNA.
Explanation:
Euchromatin is the loosely coiled chromatin and is capable of undergoing the process of transcription. On the other hand, heterochromatin is the highly coiled and compacted chromatin present in its inactive state. Active genes are associated with more loosely packed chromatin, which is the euchromatin. This is due to the fact that the DNA in euchromatin is not tightly packed which in turn allows its interaction with a transcription factor. The tightly packed DNA of heterochromatin cannot interact with proteins requires for gene expression.

Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
