Answer:

The chemical basis of Chargaff"s rule is the bonding properties of  the DNA bases.

According to the Chargaff"s rule in a DNA molecule the total number of purine bases are equal with the total number of pyrimidine bases  that means

   Adenine +Guanine=Thymine +Cytosine

In simple words the rule is based on the 1:1 ratio of both purine and pyrimidine bases.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.
