Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect.
        
             
        
        
        
Answer
            As we know that gluten is a family of protein found in grains like wheat, rice,barley etc. when it is taken by body the digestion of protein start in stomach and finish in small intestine. Here an enzyme belong to hydrolases enzymes called protease, pepsin and trypsin start digestion of protein molecules. these enzymes actually beak down the peptide bonds present amongst amino acids of protein  and release them. 
metabolism in liver
                        protein molecules along with free amino acids move towards liver in blood stream , here amino groups are removed from amino acids in the form of ammonia which are very toxic and removed from the body in the form of waste products, while the remaining compounds is converted to some other form which is then store or use in body for energy purposes,

Answer with Explanation:
The Miocene epoch was deeply characterized by<em> seasonal conditions</em>, such as having more colder winters in the northern areas.
 In the <em>late Miocene</em>,<u> open vegetation system expanded. </u>These included<em> grasslands, woodlands and shrublands.</em> As a result, more primates inhabited the area. Several habitats became diverse from each other, thus allowing the species to adapt, including their locomotion. For example, the species who used to live on trees, turn towards living on land (terrestrial life). Certain animals also came about such as <em>pigs, giraffes, monkeys, etc.</em> Scavenging hominins also scattered. When it comes to hominins, a major type of locomotion evolved called "bipedalism." <u>This allowed the hominins to walk using the lower limbs (two feet).</u>
