Answer: One way of creating a variation in a population is through genetic replication errors. This will make a new type of alleles. Environmental factors cause variation such as affecting enzyme activity and function. The changes would show in the phenotype of an organism.
Explanation: thus is one way ik for sure another way idk srry
Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.

A cell carries out all the processes of the body which includes producing energy and storing it, making proteins which are molecules which have roles in metabolism, transportation of other molecules and DNA replication.
The sum of and interaction between all living beings.<span>The biosphere is the global ecological system integrating all living organisms and their relationships. The interaction with the elements of the lithosphere, hydrosphere, and atmosphere is also included. The biosphere, we know today, has evolved for 3.5 billion years.</span>The biosphere covers most of the planet and stretches from the deep ocean to the highest mountain tops. Microorganisms also live deep beneath the surface of the Earth.The biosphere is divided into different biomes. Each of these consist of species that are related in their ability to cope with a specific climate. Biomes are separated by latitude. Arctic and Antacrtic biomes are vastly different from tropical biomes, for example.<span>Climate change influences the distribution of these biomes and to some extent displaces them.</span><span>The biosphere is an important reservoir in the carbon cycle and has a very significant impact on climate through release and removal of CO2 from the atmosphere.</span>
