The option are not given and the options are:
Proteins are denatured by breaking covalent bonds.
Linear molecules like DNA are inherently stable.
Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.
Answer:
The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
Explanation:
Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.
DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
The production of ATP energy. In cellular respiration, glucose is converted into ATP using oxygen and enzymes.

Answer:</h2>
Option C) An enzyme in her mouth broke down the polysaccharides in the cracker into monosaccharides.
<h2>
Explanation:</h2>
- This happened because of saliva present in the mouth.
- Saliva is a watery substance which is present in our mouth and secreted by salivary glands. Saliva is composed of 98% water and it contains important substances like electrolytes, mucus, antibacterial compounds and various enzymes.
- The enzyme present in saliva is amylase which helps in breakdown of some starches(polysaccharide) into maltose(diasaccharide) and dextrin. Which means, digestion of food occurs within the mouth, before the food reaches the stomach.
Result: The result come positive due to the action of saliva on cracker.
The correct answer would be A, C and D. The C4 pathway produces large amounts of carbohydrates, involves the activity of Rubisco and is the mechanism of photorespiration. This is also known as the Hatch-Slack pathway and is a photosynthesis process that occurs in some plants.
Answer:
c. the winter
The North Pole is dark for 24 hours a day in <em><u>the winter</u></em>
