The answer is; A
This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.
Answer:
This landform may have formed by the magma of the volcano making a new landform from over flowing and erupting so many times is formed a new landform
Explanation:
The answer is a. mesosphere
Earth’s atmosphere is divided into 5 layer, from the outer layer it will be: Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere. The coldest area of the atmosphere would be the middle layer called mesosphere. The average temperature of this atmosphere is −85 °C , a bit lower than stratosphere temperature −60 °C.
Nitrogen-fixing bacteria convert atmospheric nitrogen gas, which is almost inert, into solid nitrogen compounds that can then be absorbed by plants. These bacteria help fertilize the plants
