Answer and Explanation:
Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.
The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.
In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).
The intensive system of keeping livestock is performed to cater the need of growing population, as people are declining day by day, who can afford to opt for their personal cattle. Thus also known as factory farming, where large amount of cattle are treated with full hygiene and facilities to produce more products like milk and milk products, egg, meat, etc. and with less cost. The basic features of intensive system are as follows:
- The area required for such farming is small as compared to general, thus less land can fulfill the need of large population.
- The method and technology used give employment to skilled workers and follow more rules and regulations to protect livestock from diseases.
- Help in maintaining economical aspects in national level, by increasing production in bulk with comparatively less input.
Through a cut or an injury where any skin has been broken.
An infection through an animal's bite or sting.(Like the West Nile Virus which spreads though mosquito bite, or Rabies though an infected mammal's bite).
Can be inhaled or consumed and go from the lungs into the other organs causing harm internally.
Carbon forms the key component for all known life on Earth. Carbon is the basis of all molecules. Its is easily able to bond because of the 4 valence electrons.
Answer:
physical, or biological anthropology.
Explanation:
When there is a need to study human kind through the X-ray of relationships between human biology, its cultural diversity, and evolution ,the aspect anthropology for this is Biological anthropology.
Therefore biological anthropology is concerned about how the interaction between the cultural diversity and biological process results in the adaptations of mankind to different environments.The influence of these on growth, behaviours, existence.
The primary focus of biological anthropologists is to study in details the concept of ,mechanism of variation, adaptation.and how these lead to evolution and origin of mankind.
Sequel to this ,most evidences for this concept are obtained from the study of fossil materials,study of other related primates to man, and components of functional biology and genetics.
