Gas density creating our atmosphere
The most significant advantage of using renewable energy sources is that is sustainable (as a result of the fact that is renewable) and the low Greenhouse Gas Emissions.Renewable energy sources do not pollute the environment it with Co2 and other toxic gases that are produced by fossil fuels.
Correct answer is B.
Explanation:
In their nucleus cells contain DNA. The DNA has information about size, shape and function of each cell. When the cell reaches it's full size it stops growing and starts doing whatever it's function is. If more cells are needed then the cell replicates. This explanation excludes answers A and C.
Male and female sexual cells are used to conceive a baby. These cells combine to form a new type of cells. In the first few weeks all types of cells are created. Then the creation of new types of cells stops and existing cells multiply in order to achieve needed number of cells. This explanation excludes answer D.
When we compare an adult person and a baby we can see that, for example, an adult has bigger bones than a baby. This was result of increasing number of existing types of cells without creating any new type.
Answer:
When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens
Explanation:
Answer:
The amount of tectonic activity along the margin
.
Explanation:
<u>Margins are categorized as passive when the tectonic activity along it is poor.</u> This is manifested through rare to non-existent <em>earthquakes</em> and <em>volcano eruptions</em> in the area.
On the other hand, <u>active margins are characterized by frequent tectonic activity.</u> This means <em>mountain formation, earthquakes, and volcano activity</em> are not strange here.
