Answer:
Explanation:
The higher temperature is the factor which is responsible for the process of denaturation of proteins in which the breaking down of hydrogen, disulphide bonds and destabilization occurs. This process breaks up the bond between the polypeptides. 
The bovine pancreatic trypsin inhibitor comprises of 58 amino acids this consists of the disulphide bonds which are destroyed on heating as a result of this the inhibitor becomes inactive. But on cooling it comes to the original form as the internal structure starts making hydrogen and disulphide bonds again. Thus the activity of the BPTI again gets restored.  
 
        
             
        
        
        
Answer:
Plants extract energy from food molecules the same way animals do — by cellular respiration. When plants do cellular respiration, they produce carbon dioxide and use oxygen just like animals do
 
        
             
        
        
        
<span>Answer B, skin, is an example of epithelial tissue. All other answer are examples of different types of tissue; Bone being osseous tissue, fat being connective tissue and muscle being muscle tissue. Nervous tissue is one of the types that has cells that expand across the entire human body. Nerves can be both long and reach every corner of the body. The other type of tissue that can cross the entire body is epithelial. This type of tissue does not produce large cells that span great distances on/in the body. But, these cells do provide the lining throughout the body and are the tissue that makes up the protective layer called skin. Both connective tissue and muscle tissue form large amounts of tissue in the body but they do not expand to all reaches of it.</span>
