Which is true of dna viruses?
they use the host cell’s machinery to produce new copies of their genome.
they all have envelopes.
they are the only kind of viruses that can cause cancer.
they are not important plant pathogens.

They use host cell machinery to produce new copies of their genome.

Explanation:

DNA viruses, which are similar to cells, directly employ cellular machinery to perform their process of replication, transcription of their genes, and DNA repair, that is, they use a host cell to make new copies of their genome. Because of this, some viruses have a large genome, such as herpesviruses, which make their own genes and become somewhat more independent of cell metabolism.  DNA molecules are found in two forms: linear and circular. Viruses of the polyomaviridae family have small genomes and circular DNA, while herpesviruses have linear dsDNA genomes. Viruses that have single strand genomes do not allow DNA repair.

i believe the answer would be b. hope it : )

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
