<span>All natural disasters affect the ecosystem. They affect lands, forests, and coasts and cause death to people, plants and animal species, the spread of invasive species, and loss of habitat. In the short term, they cause climate change but over time, there are some types of natural disasters that increase biodiversity in the long run. Examples of these are earthquakes, landslides, volcanic eruptions, and wildfires. They play an important role in rejuvenating the ecosystem that they once destroyed.</span>
In this question, let us cite one specific example:
<span>1. </span><span>Volcanic eruption. The eruption has an immediate negative effect on surrounding, but through primary succession, the forest begins re-colonization almost immediately. Many plants, insects, and animal species arrive from adjacent places to take up residence. These life forms are adapted to survive in the severe conditions following volcanic eruption causing a new and more diverse forest ecosystem that will last a 150 year period.</span>
Answer:
DNA Helicase
Explanation:
The process of DNA replication is very complex and requires a variety of proteins in the form of Enzymes.
The DNA replication starts at the site which is about 245 base pairs long and is rich in AT sequences called Origin of replication. The origin of replication recognised by an enzyme called DNA helicase which breaks the hydrogen bonds present between the bases and unwinds the DNA. The RNA primase enzymes then synthesizes an RNA primer which gets attached and to which DNA polymerase binds and add nucleotides.
Thus, the first enzyme that binds to the DNA is DNA helicase.
<span>This person is experiencing common physical symptoms of what is called "withdrawals". Opiates, when used illegally, can be highly addictive. This drug targets the central nervous system (the brain, cardiovascular and respiratory systems) and contains opioid receptors that receive opiate drugs. Abusing this drug can disrupt a person's brain chemistry, leading to severe physical withdrawal symptoms as listed in the question.</span>
