Answer: Helicase
Explanation: Replication is a process of making two identical copies of DNA from a double-stranded DNA. This process is catalyzed by an enzyme called DNA polymerase. Before DNA polymerase begins the synthesis of the new strands, helicase will unwind or unzip the double-stranded DNA. Helicase is the enzyme that unzips or unwinds the double-stranded DNA helix during replication. Helicase separates the two strands by moving along the DNA using chemical energy from ATP. The separated strands serve as templates for the synthesis of new DNA strand.
The answer would be water. If this isn’t it I’m sorry , I’ve tried!
1 Viruses are not alive, bacteria are.
<span>2 Viruses must replicate in a host cell; bacteria can replicate on their own </span>
<span>3 Viruses are much smaller </span>
<span>4 Viruses have a protein layer called caspid </span>
<span>5 Viruses cannot be killed with antibiotics; bacteria can be. (If you have a virus that makes you sick, you can only treat the symptoms, not the actual bug itself)</span>
Primary succession takes place when barren land is exposed and made available for plant growth.
The first step is the retreat of the glacier. Next, pioneer species begin to inhabit the exposed land. These species include lichens and they break down rocks and create soil. Some years later, more complex plants start growing in the soil and insects also begin to inhabit it. The remains of all of these organisms add nutritional value to the soil. As soil thickens, more complex plants and animals inhabit the region, until finally, the soil is thick enough for entire forests to grow.
