DNA is bound together by covalent bonds between different molecules. It also contains proteins, which again are held together in their specific structures by covalent bonds. 

Covalent bonds may be broken when high temperatures are applied. The temperatures that a food encounters during the cooking cause the DNA to be denatured, meaning it cannot be extracted. The same occurs with other proteins such as enzymes and antibodies.

Answer:

(c) 16-24 calories

Explanation:

In the  question it is provided that 4 - 6g of  highly concentrated glucose product helps to get on the feet within 20 to 30 minutes.

Also we know that 1 gram of glucose contains 4 calories.

Therefore,

4g of glucose = 4 × 4 calorie

                       = 16 calories

6g of glucose = 6 × 4 calorie

                       = 24 calories

Thus, we can say that the minimum number of calories needed to bounce back after the workout is 16 - 24 calories

Hence, the correct answer is option (c) 16-24 calories

What is true of carbon atoms? (2 points)
Rudiy27
By process of elimination you can find the right answer. We know for a fact that carbon is found in all living organisms. That is why we talk about carbon based life forms. So the first statement cannot be true. You can figure out how many Valence electrons an element has by looking at the group number. The group number of carbon is 4 so the 2nd statement cannot be true. We know that carbon does bond with other elements because it is not a noble gas and therefore must be able to form compounds.
This means the answer must be they can form up to four covalent bonds

Sublimation is the opposite of deposition just as evaporation is the opposite of fusion transpiration freezing condensation
Lena [83]
<span>A condensation is a process where liquid changes into a gaseous form also known as water vapour. It occurs in the atmosphere when the temperature rises.
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.</span><span>
