Radiation is responsible for the greatest loss of energy.
Answer:
Georgia is the world's leading producer of Kaolin (china clay).
Explanation:
Kaolin or china clay contains the mineral kaolinite mainly. It also contains varying amounts of other minerals like muscovite, feldspar, quartz, etc. In order to prepare it for commercial use, the clay in its natural form is then chemically treated and washed with water to remove the other minerals.
Kaolin is extensively used in the ceramic industry and the paper-coating industry. The high fusion temperature and white burning characteristics are used in the ceramic industry for the manufacture of chinaware, porcelain, and refractories. In the paper-coating industry, the kaolin is mixed with the cellulose fiber in the paper sheet. This gives the paper its color, opacity, and printability. It is also used as a pigment additive in paints, as a filler in plastic and rubber compounds, and in pharmaceuticals.
Answer: In an ionic bond the valence electrons are transferred from the metal only to the neighboring nonmetal, but in metallic bonding the valence electrons of each atom/ion are free to move or float around within the entire metal solid.
Explanation:
Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.
Answer:
A Single amino acid must be polar to attract, just like water.
Explanation:
Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.
