Answer:
Explanation:
1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..
2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.
3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.
4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.
5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.
6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Answer:
it is determined by their environment
Explanation:
Remember homeostatsis is when an organism's body tries to maintain adequate body temperature.This is done through the method of cooling.Furthermore ,in humans we sweat in order to achieve this cooling effect .that being said the only one here that would make sense is C)A dog panting after a long walk on a hot July day.The reason this answer would be correct is becausethis is a dog's method of cooling ,as they don't have sweat glands .Therefore they pant to maintain homeostasis.
Answer: You can consult:
One solution is to limit the scope of the study. Another possibility
is do several smaller studies over a longer period of time.
Explanation:
I'm not sure but hope it helps.
