Answer:

B. positive

Explanation:

Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.

How does conduction differ from convection?
Free_Kalibri [48]

Answer:

Explanation:

I think the first one is correct.

The second one is half right (conduction works mostly in solids). The second part is not correct. Convection works mostly in gases.

The third one is wrong about waves. Conduction usually has direct contact of particles.

The last one is not correct. There is no visible movement of matter in conduction. The definition for convection is also incorrect.

Answer:

The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
