I am sure for all , so go for that !! If you got any problem, you can tell !!
Explanation:
For question no 19
Force (F) = 20N
distance (d) = 5m
Work = F * d
= 20 * 5
= 100 J
Now
For question no 20
D. No matter how much force is applied the object must have motion for work to be done.
The skeletal system since the brain is apart of the skeletal system.
Answer:
The correct answer is: translesion.
Explanation:
Also called DNA polymerase V, the translesion polymerase is responsible for the repair of the DNA in prokaryotes like Escherichia coli.
These special enzymes repair DNA lesion during DNA replication. If the enzyme fails, the damage in the DNA can lead to the death of the cell.
Replication in prokaryotes is much more prone to errors than replication in eukaryotes, one of the reasons being this polymerase not being as effective as the polymerase in charge of repairing eukaryotic DNA, the DNA polymerase beta.
