The chemical bonds that hold the two strands of DNA together are hydrogen bonds.
- Deoxyribonucleic acid (DNA) is a double helix composed of two long chains of nucleotides linked together via hydrogen bonds.
- In DNA, there are four different classes of nucleotides, each one containing one different nitrogenous base (i.e., Adenine, Thymine, Guanine and Cytosine).
- According to the base pair rules, Adenine always pairs with Thymine via two hydrogen bonds, whereas Cytosine always pairs with Guanine via three hydrogen bonds.
In conclusion, the chemical bonds that hold the two strands of DNA together are hydrogen bonds.

The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
The scientific methodology is also referred to as scientific method, it is the problem solving approach that is used in science. The scientific method ls made up of the following steps: observation, formation of research question, formation of hypothesis, making prediction and conduction of experiment {testing out the prediction}.
The answer is:
<em><u>Carbohydrates give our bodies energy like sugars, glucose, fructose, sucrose and lactose. When you eat carbs, your body breaks them down into simple sugars then are absorbed into your bloodstream</u></em>
Hopefully this helped :)
