The classification of organisms is achieved in the branch of science called taxonomy. Classification is important in order for future references and understanding of the common properties and characteristics of organisms for research and easy skimming of characteristics. This is for organization and convenience purposes
~over hunting has killed a lot of species
~we genetically modify plants and animals to our liking
~we have introduced a lot of invasive species to different places effecting local wildlife
The answer is true.
<span>Antigens are molecules capable to induce an immune response, "targeted" by antibodies. Antigens are usually proteins, peptides, or polysaccharides but they can combine with lipids and nucleic acids and form more complex antigens (lipopolysaccharide). Usually, antigens are exogenous (foreign substances), but sometimes are part of the host itself (in an autoimmune disease). All of them contain an epitope which is a part of an antigen that can be recognized and bound by an antibody.</span>
Answer: We can tell how life existed on earth and how different plants and animals are related to each other. Often we can work out how and how and where they lived, and use this information to find out about ancient environments. Fossils can tell us about the past.
Explanation
It is important to prevent soil erosion, because when soil is eroded is can lead to the <em>pollution of water</em> around it/ water that passes through it. Since water is one of the basic necessities of all life, polluted water and cause illness or death among humans, plants, or animals. As soil is eroding, the <em>quality of it is reduced</em>. This disturbs plant life and agriculture.
Ways to prevent soil erosion:
- crop rotation
- increased vegetation
- terracing
- strip cropping
