Answer: a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.
Explanation: The purpose of DNA replication is to produce genetically identical DNA molecules.
Replication is the process of copying a double-stranded DNA molecule into two identical daughter DNA. The enzyme known as helicase unwinds the DNA so that each strand will serve as a template for the synthesis of a complementary DNA strand. The. Two identical daughter DNA produced each contains one parent DNA strand and one new complementary strand.

Answer:
An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.
Explanation:
They make up an ecosystem that resides in an environment. For example, a rainforest is an environment that contains ecosystem like the trees, plants, animals and insects, the temperature, humidity and kind of soil.
