Tapping of geothermal energy
to produce electricity is done on a larger scale compared to the tapping of
the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area
of convection boundaries while geothermal
gradient can be harnessed virtually
anywhere on the earth surface.

Explanation:
<em>Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer</em>
<em>The answer is </em><em>no</em><em>. My friend's explanation is not a scientific theory.</em>
A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.
Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".

Sexual reproduction... and what is your question again
if your looking for the definition then here it is
the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete that travels to fuse with a larger stationary gamete produced by the other (female).
Answer:
A. Water molecules have strong intermolecular attractions.
Explanation:
Water molecules have strong intermolecular attractions due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating.
