2 points
question 2
which statement about energy generated from wind is true?
wind is free "fuel," and government taxes on its use are lower than those on fossil fuel use.
wind power gives off no greenhouse gases, but some people feel it spoils the view of the landscape.
wind power uses more water than coal power plants, but it is a far safer power source for wildlife.
wind power is abundant everywhere, and battery storage of excess power is very inexpensive.

1- Option (A)

2- Option (B)

3- Option (A)

4- Option (C)

5- Option (A)

Explanation:

The wind energy is one of the most efficient uses of energy as it does not create any kind of pollution. There occurs no emission of greenhouse gases that are responsible for the rise in global temperature. Whereas it is helpful in the conversion of wind energy into electrical energy. It is inexpensive and renewable and very favorable at the site where there is constant wind.

Geothermal energy is defined as the energy that is obtained from the interior of the earth. It is very widely used and it is clean as well as cost-effective. There are abundant geothermal energy.

Tidal energy is a type of renewable energy which is very useful in the production of electricity as it converts kinetic energy into electrical energy. The tidal energy is more favorable in the region where there is constant fluctuation of tides, in which the blades (turbines) are used for the production of electricity.  It emits no green house gases.

Thus, the correct answers are mentioned above.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
