Answer:
Meteoric impact
Explanation:
An impact crater is usually defined as a circular depression or large scale pit that forms when any meteorite hits the surface of planet or moon or any other astronomical object. This causes immense destruction, wiping out a large number of area. The size of the crater depends upon the size of the meteorite or asteroid. For example, the Barringer crater, which is formed due to the meteoric impact on the earth. This crater is located in Arizona and is primarily comprised of a mineral, known as stishovite, which forms under the condition of extremely high pressure, that is generally caused by a high-speed impact.
Complementary pairing goes like this:
A pairs with T and
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)
So if you have a strand that goes TCG GA then your pairing will look like this:
T A
C G
G C
G C
A T
Hope this helps!! :)
The answer is C, because of the propellant gas released when the contaminated soil is mixed and released of pressures.
Explanation:
C- both of these terms are interchangeable.
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
