Answer:
They are produced or originated from an epithelial sheet(like the endocrine glands) but will never lose the duct connecting them to the free surface of the epithelial sheet (surface of the skin or lumen of the open body cavities. They transport their product through a duct on the epithelial surface.
They transport their product through a duct on the epithelial surface.
I believe that if kinetic energy were to decrease, then the speed would decrease because the more kinetic energy an object has, the more speed an object has.
1. Our results showed that test tube B contained end products of protein digestion, meaning that the isolated enzyme has the ability to break down protein. The end products of protein digestion include small polypeptides, dipeptides, and amino acids. In general, test tube B will contain the building blocks of proteins, which are the amino acids.
2. The two test tubes were placed in a hot water bath at 37oC. This is because the enzyme studied is a human enzyme and it works best at the human body temperature, which is approximately 37oC.
Enzymes are biological catalysts, which means that they accelerate chemical reactions. As a result, an enzyme's activity is greatly affected by temperature. Every enzyme, depending on each function and origin, has a specific range of ideal temperature conditions. If the temperature rises above the maximum accepted, then the enzyme denatures and loses its structure.
3. If the enzyme studied was added in a tube containing starch instead of proteins, then nothing would happen. This is because the enzymes are highly specialized and have very specific actions. It has been proved that this enzyme's activity involves the digestion of proteins.
Starch is a polysaccharide produced by plants, this means that starch is a carbohydrate. Given that starch is not a protein, it will not be digested by the enzyme. An enzyme digesting proteins, will not have any effect on carbohydrates.
4. The smaller molecules which are the result of the digestion happening in the digestive system are absorbed by the human body. More specifically, the products of protein digestion are absorbed by the intestine and then transported into the bloodstream. From the blood, they are then absorbed by other tissues.
After they are absorbed, they are used to build muscles or other compounds which can produce energy.
You did not include the diagram, but the answer is very easy to figure out. The mRNA base that will go in location 1 depends on the DNA base in location 1:
If the DNA base is Adenine (A), the mRNA base will be Uracil (U)
If the DNA base is Thymine (T), the mRNA base will be Adenine (A)
If the DNA base is Cytosine (C), the mRNA base will be Guanine (G)
If the DNA base is Guanine in (G), the mRNA base will be Cytosine (C)
