In driving a vehicle, the crash risk potential is approximately 4 times greater after dark than during the daylight hours according to the US Department of Transportation, Federal Highway Administration. This is due to the reduced visibility of the streets at night as well as direct bright light shining to drivers' eyes by the vehicles going the opposite way. This is also increased when there is heavy rain which further reduces the visibility.
Answer:
D
Explanation:
Diffusion and osmosis are both passive forms of transport because there is no energy need to transport something such as water from an area of high pressure, to an area of low pressure.
Answer:
d. error-prone repair
Explanation:
DNA polymerases are the enzymes responsible for synthesizing DNA, not only making faithful replicas of our chromosomes, but also carrying out the necessary repairs for the proper maintenance of your genetic information. Either due to the intensity of the genotoxic damage or due to defects in the repair machinery, the ideal situation of having a pristine, original mold of DNA for copying is not always possible, which explains the existence of a special type of DNA polymerases, specialized in tolerating various DNA lesions through a copy process called "translesion synthesis" which is an "error-prone" or error-guaranteeing.
There is also a new human translesion DNA polymerase, perhaps the oldest of all, and that is capable of initiating the synthesis of new DNA chains acting as a primase. This enzyme, called PrimPol, is present in both cellular compartments that contain DNA (the nucleus and mitochondria). Through gene silencing experiments it was shown that PrimPol is necessary for mitochondrial DNA replication, probably tolerating the high oxidative damage associated with the respiratory activity of these organelles.
