Answer:
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
The red line on the figure below shows how temperature varies with height (the temperature scale is given along the bottom of the diagram). The scale on the right shows the pressure. For example, at a height of 50 km, the pressure is only about one thousandth of the pressure at the ground.
Well first off, Mendel’s law of segregation states that individuals possess two alleles and a parent passes only one allele to his/her offspring. Mendel’s law of independent assortment states the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair. Now Mendel discovered this through his little experiment with the pea plants that showed certain traits through a particular pattern, subsequently becoming the foundation of modern genetics and heredity.
I think you forgot to give the options related to the question. So it becomes a bit hard to answer the question perfectly, still i would do my best and hope that it comes to your help. Prior to the ideas presented by Charles Darwin concerning evolution, several alternating theories had been developed and they included all but the DNA differences within a species lead to some individuals being better able to survive. This theory was developed after Darwin came up with his theory..
