If u know the water cycle please answer this question
Ksju [112]

Answer:

Gravity

Explanation:

Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.

Evaporation-the process of turning from liquid into vapor.

Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.

and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two
liberstina [14]

Answer:

A. Helicases

B. Single strand binding proteins

C. Single strand binding protein

D. Topoisomerases

Explanation:

The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
